Answer: Option (B) is the correct answer.

Explanation:

As we know that the temperature when the vapor pressure of liquid becomes equal to the atmospheric pressure surrounding the liquid. And, during this temperature liquid state of substance changes into vapor state.

But during this process of change in state of substance the temperature will cease to change for some time because unless and until all the liquid molecules do not convert into vapor state the temperature will not rise or change.

As the boiling point of water is [tex]100^{o}C[/tex] so the temperature ceases to change from [tex]98^{o}C[/tex] to [tex]102^{o}C[/tex].

Therefore, we can conclude that when heating water, during [tex]98^{o}C[/tex] to [tex]102^{o}C[/tex] temperature range the temperature will cease to change for some time.

Explanation:

Poiseuille's law can be used to solve for the radius of the pipe

Volume per seconds flowing through the pipe = 7.3 / (51 × 60 s) = 0.0239 m³ / s

volume per seconds = π R^4 ( Pi - Po) / ( 8 ηL) where R is the radius of the pipe in mm, (Pi - Po) is the pressure difference in Pa, L is the length of the pipe in meters, and η is the viscosity in Pa.s

Pi - Po = ( 7.4 - 1.01) × 10^5 since 1 atm represent atmospheric pressure and it is equal to 1.01 × 10^5

Pi -Po = 6.39 × 10^5

substitute the values into the equation

0.00239 = 3.142 × (R^4) × 6.39 × 10^5 / ( 8 × 11 × 0.934)

cross multiply

0.00239 × 8 × 11 × 0.934 = (R^4) × ( 2.01 × 10^6)

make R subject of the formula

R^4 = (0.00239 × 8 × 11 × 0.934) / ( 2.01 × 10^6)

R = [tex]\fourthroot{9.77 * 10^-8}[/tex]

a) The coin reaches a maximum height of approximately 1.28 meters above the release point.

b) The coin remains in the air for approximately 1.02 seconds before returning to the release point.

We calculate the maximum height and total air time of a football coin tossed with an initial speed of 5 m/s, neglecting air resistance.

a) Maximum Height:

Use the vertical motion equation: [tex]v^2 = u^2[/tex] + 2gh, where v = 0 at the peak (no upward velocity), u = 5 m/s (initial speed), g = 9.81 m/[tex]s^2[/tex] (gravity), and h is the unknown maximum height.

Rearrange and solve for h: h = ([tex]v^2 - u^2[/tex]) / 2g ≈ 1.28 meters.

Therefore, the coin reaches a maximum height of approximately 1.28 meters above the release point.

b) Total Air Time:

Since the initial and final velocities at the release point are equal but in opposite directions, the total air time can be calculated twice the time to reach the peak.

Use the same vertical motion equation: t = u/g ≈ 0.51 seconds.

Total air time: 2t ≈ 1.02 seconds.

Therefore, the coin remains in the air for approximately 1.02 seconds before returning to the release point.

Answer:

a) I = 270.18 Kg*m/s

b) F = -3216.42N

Explanation:

a) We know that:

I = [tex]P_f -P_i[/tex]

Where I is the impulse, [tex]P_f[/tex] is the final momentum and [tex]P_i[/tex] the initial momentum.

so:

I = [tex]MV_f -MV_i[/tex]

where M is the mass, [tex]V_f[/tex] is the final velocity and [tex]V_i[/tex] is the initial velocity.

First we have to find the [tex]V_i[/tex]. So, using the conservation of energy.

[tex]Mgh = \frac{1}{2}MV_i^2[/tex]

where g the gravity and h the altitude. Replacing values, we get:

[tex](79kg)(9.8m/s)(0.6m) = \frac{1}{2}(79kg)V_i^2[/tex]

solving for [tex]V_i[/tex]:

[tex]V_i[/tex]= 3.42 m/s

Now, replacing in the previus equation:

I = [tex]MV_f -MV_i[/tex]

I = [tex](79kg)(0)-(79kg)(3.42m/s)[/tex]

I = -270.18 Kg*m/s

The impulse is negative becuase it is upward.

b) We know that:

Ft = I

where F is the force, t the time and I the impulse.

so, replacing values and solving for F, we get:

F(0.084s) = -270.18 Kg*m/s

F = -3216.42N

The force is negative becuase it is upward.

Answer:

113.7

Explanation:

maximum distance (s) = 8.9 km

reference intensity (I0) = 1 x 10^{-12} W/m^{2}

power of a juvenile howler monkey (p) = 63 x 10^{-6} W

distance (r) = 210 m

intensity (I) = power/area

where we assume the area of a sphere due to the uniformity of the output in all directions

area = 4π[tex]r^{2}[/tex] =  4π x [tex]210^{2}[/tex] = 554,176.9 m^{2}

intensity (I) = [tex]\frac{63 x 10^{-6} }{554,176.9} = 113.7 x 10^{-12}[/tex]

therefore the desired ratio I/I0 = [tex]\frac{113.7 x 10^{-12}}{1 x 10^{-12}}[/tex] = 113.7

To find the ratio of the acoustic intensity produced by the juvenile howler to the reference intensity I0, you need to calculate the acoustic intensity at a distance of 210 m. By using the formula I = P / A, you can find the acoustic intensity by calculating the power emitted by the source and the area through which the sound is passing. Then, find the ratio of the acoustic intensity produced by the juvenile howler to the reference intensity I0 by dividing the calculated acoustic intensity by I0.

To find the ratio of the acoustic intensity produced by the juvenile howler to the reference intensity I0, we need to calculate the acoustic intensity at a distance of 210 m.

Acoustic intensity is given by the formula:

I = P / A

where I is the acoustic intensity, P is the power emitted by the source, and A is the area through which the sound is passing.

First, convert the power of the juvenile howler monkey from 63 μW to watts:

P = 63 x 10^-6 W

Next, calculate the area through which the sound is passing:

A = 4πr^2

where r is the distance of 210 m.

Finally, calculate the acoustic intensity:

I = P / A

Now, find the ratio of the acoustic intensity produced by the juvenile howler to the reference intensity I0 by dividing the calculated acoustic intensity by I0:

Ratio = I / I0

The amount of light a telescope collects is proportional to the square of its diameter. A 2-m telescope would need four times as long to collect the same amount of light as a 4-m telescope. Therefore, it would take 40 minutes for a 2-m telescope to collect the same amount of light that a 4-m telescope can in 10 minutes.

The amount of light collected by a telescope is proportional to the square of its diameter. In other words, a telescope with twice the diameter will collect four times as much light. Hence, a 4-m telescope will collect light four times as fast as a 2-m telescope, given that everything else (including observational conditions) remains constant.

This means that to collect the same amount of light, a 2-m telescope would need four times longer than a 4-m one. So, if a 4-m telescope collects a certain amount of light in 10 minutes, a 2-m telescope would need 40 minutes to collect the same amount of light.

Answer:

212.12 J

Explanation:

As the child starts from rest and rolls down on the incline, the potential energy of the child decreases due to decrease in the height. This drops in potential energy appears as an increase in kinetic energy of the child as it gains speed. hence kinetic energy gained by the child at the bottom is same as the potential energy of the child at the top.

[tex]m[/tex] = mass of the child = 37 kg

[tex]L[/tex] = length of the incline surface = 2.0 m

[tex]\theta[/tex] = angle of the incline from the horizontal = 17 deg

[tex]K[/tex] = kinetic energy of the child at the bottom

height of the incline surface is given as

[tex]h = L Sin\theta\\h = (2.0) Sin17.0\\h = 0.585 m[/tex]

[tex]PE[/tex] = Potential energy of the child at the top

Potential energy of the child at the top of incline is given as

[tex]PE = mgh \\PE = (37) (9.8) (0.585)\\PE = 212.12 J[/tex]

Using conservation of energy

Kinetic energy at the bottom = Potential energy at the top

[tex]K = PE\\K = 212.12 J[/tex]

To find the kinetic energy of the child at the bottom of the incline, calculate the potential energy at the top and equate it to the kinetic energy at the bottom due to energy conservation, as there is no friction.

The subject of this question is Physics, specifically focusing on the topics of energy and motion on inclines. To find the kinetic energy of the child at the bottom of the incline, you would need to calculate the potential energy at the top of the incline and assume it transforms into kinetic energy at the bottom due to conservation of energy, as there is no friction to dissipate it.

To calculate the potential energy (PE) at the top of the incline, you can use the formula: PE = mgh, where m is the mass of the child, g is the acceleration due to gravity (9.8 m/s2), and h is the height of the incline.

The height can be found using trigonometry, since h = s sin(θ), where s is the length of the incline and θ is the angle of the incline with respect to the horizontal. Once you find the PE, this will equal the kinetic energy (KE) at the bottom of the slope, so KE = PE. Plug in the values (mass of 37 kg, length of the slope 2.0 m, angle 17 degrees) to solve for the kinetic energy.

Answer:

If the canoe heads upstream the speed is zero. And directly across the river is  8.48 [km/h] towards southeast

Explanation:

When the canoe moves upstream, it is moving in the opposite direction of the normal river current. Since the velocities are vector (magnitude and direction) we can sum each vector:

Vr = velocity of the river = 6[km/h}

Vc = velocity of the canoe = -6 [km/h]

We take the direction of the river as positive, therefore other velocity in the opposite direction will be negative.

Vt = Vr + Vc = 6 - 6 = 0 [km/h]

For the second question, we need to make a sketch of the canoe and we are watching this movement at a high elevation. So let's say that the canoe is located in point 0 where it is located one of the river's borders.

So we are having one movement to the right (x-direction). And the movement of the river to the south ( - y-direction).

Since the velocities are vector we can sum each vector, so using the Pythagoras theorem we have:

[tex]Vt = \sqrt{(6)^{2} +(-6)^{2} } \\Vt=8.48[km/h][/tex]

When paddling upstream against a current of equal speed, the canoe remains stationary (0km/hr), as the man's paddling counteracts the downstream current. If the man were to paddle the canoe directly across the river, the speed of the canoe would be 6 km/hr, since the river's current doesn't directly impact the speed he can move perpendicular to the current.

This question deals with the concept of relative motion in Physics. When the man paddles the canoe upstream, he is going against the river current. Therefore, the effective speed of the canoe is the difference between his paddling speed and the river current speed, i.e., 6 km per hour (canoe speed) - 6 km per hour (current speed) = 0 km per hour.

When the man paddles the canoe directly across the river, the river's current doesn't directly affect his progress across the river. Thus, the speed of the canoe remains the speed with which the man paddles it, i.e., 6 km per hour. However, the path will not be straight because of the river's current. It is essential to understand these principles to solve similar problems involving relative motion.

Answer:

the ratio F1/F2 = 1/2

the ratio a1/a2 = 1

Explanation:

The force that both satellites experience is:

F1 = G M_e m1 / r²       and

F2 = G M_e m2 / r²

where

Therefore,

F1/F2 = [G M_e m1 / r²] / [G M_e m2 / r²]

F1/F2 = [G M_e m1 / r²] × [r² / G M_e m2]

F1/F2 = m1/m2

F1/F2 = 1000/2000

F1/F2 = 1/2

The other force that the two satellites experience is the centripetal force. Therefore,

F1c = m1 v² / r    and

F2c = m2 v² / r

where

Thus,

a1 = v² / r ⇒ v² = r a1    and

a2 = v² / r ⇒ v² = r a2

Therefore,

F1c = m1 a1 r / r = m1 a1

F2c = m2 a2 r / r = m2 a2

In order for the satellites to stay in orbit, the gravitational force must equal the centripetal force. Thus,

F1 = F1c

G M_e m1 / r² = m1 a1

a1 = G M_e / r²

also

a2 = G M_e / r²

Thus,

a1/a2 = [G M_e / r²] / [G M_e / r²]

a1/a2 = 1

1. The ratio of the gravitational force on the first 1000 kg satellite to that on the second 2000 kg satellite is 1/2.

2. The ratio of the acceleration of the first 1000 kg satellite to that of the second 2000 kg satellite is also 1/2.

The gravitational force (F) between two objects is given by the equation:

F = G * (m1 * m2) / r²

Where:

- F is the gravitational force.

- G is the universal gravitational constant.

- m1 and m2 are the masses of the two objects.

- r is the distance between the centers of the two objects.

In this case, both satellites are in the same orbit around the Earth, so their distances from the center of the Earth (r) are the same.

Let's calculate the ratio F1/F2 for the first satellite (mass m1) and the second satellite (mass m2):

F1/F2 = (G * m1 * m_Earth) / r² / (G * m2 * m_Earth) / r²

F1/F2 = (m1 * m_Earth) / (m2 * m_Earth)

Now, we have m_Earth in both the numerator and denominator, so it cancels out:

F1/F2 = m1 / m2

So, the ratio of the gravitational force on the first satellite (F1) to that on the second satellite (F2) is simply the ratio of their masses, which is:

F1/F2 = 1000 kg / 2000 kg = 1/2

Now, let's calculate the ratio a1/a2 for the accelerations of the first satellite and the second satellite. The acceleration due to gravity is given by:

a = G * (m_Earth) / r²

Since both satellites are at the same distance (r) from the center of the Earth, the ratio a1/a2 is the same as the ratio of their masses:

a1/a2 = m1 / m2 = 1000 kg / 2000 kg = 1/2

So, the ratio of the acceleration of the first satellite (a1) to that of the second satellite (a2) is also 1/2.

To convert between the two forms, we use the cosine of a sum identity, which states that:

cos(a + b) = cos(a)cos(b) - sin(a)sin(b).

For part (A), expressing Acos(ωt+φ) in the form of Ccos(ωt) + Ssin(ωt), we get:
C = A cos(φ),
S = -A sin(φ).

For part (B), deriving A and φ in terms of C and S from the second equation, we use the Pythagorean identity and the definitions of cosine and sine to get:
A = √(C²+S²),
φ = atan2(S, C).

The constants C and S can be expressed in terms of A and ϕ as C = A cos(ϕ) and S = -A sin(ϕ). Conversely, A and ϕ can be expressed in terms of C and S as A = √(C² + S²) and ϕ = tan⁻¹(-S/C).

Explanation:

Part A: Expressing C and S in terms of A and ϕ

The given forms are:

We can use the trigonometric identity for the sum of angles to rewrite A cos(ωt + ϕ):

Comparing this with x(t) = C cos(ωt) + S sin(ωt), we identify:

Part B: Expressing A and ϕ in terms of C and S

From the relationships above:

Explanation:

As the distance between a planet and the sun increase, the following quantities will decrease.

1. The gravitational force is given by :

[tex]F=G\dfrac{m_1m_2}{r^2}[/tex]

As the distance between a planet and the sun increase, the gravitational force decrease.

2. As the distance between a planet and the sun increase, it result in the decrease in its speed. Due to decrease in gravitational force, centripetal force acting on the planet should decrease. Since,

[tex]F_c=\dfrac{mv^2}{r}[/tex]

v is the tangential speed

So, the tangential speed must decrease.

3. The distance traveled in a day should decrease.

Hence, this is the required solution.

Answer:

Speed of Tarzan at the bottom of the swing is 12.5 m/s.

Explanation:

Given that,

Length of the vine, L = 31 m

The swing is inclined at an angle of 42 degrees with the vertical. We need to find the speed at the bottom of the swing if he pushes off with a speed of 6.00 m/s. using the conservation of mechanical energy as :

[tex]mgh=\dfrac{1}{2}mv^2[/tex]

[tex]gh=\dfrac{1}{2}v^2[/tex]

h is the height of the height.

[tex]h=L-L\ cos\theta[/tex]

[tex]v=\sqrt{2gh}[/tex]

[tex]v=\sqrt{2gL(1-\ cos\theta)}[/tex]

[tex]v=\sqrt{2\times 9.8\times 31(1-\ cos(42))}[/tex]

v = 12.492 m/s

or

v = 12.5 m/s

So, his speed at the bottom of the swing if he pushes off with a speed of 6.00 m/s is 12.5 m/s. Hence, this is the required solution.

Option b.

By making use of the conservation of mechanical energy principle and using trigonometric relations, we find that Tarzan's final speed as he reaches the bottom of his swing is approximately 12.55 m/s, hence answer choice (B) 12.5 m/s is the closest.

To solve this problem, we need to recognize that this is a problem about the conservation of mechanical energy. Initially, Tarzan has both kinetic energy (because he pushes off with a speed of 6.00 m/s) and potential energy (because he is at a height above the lowest point of the swing). At the bottom of the swing, all of this energy will have been transformed into kinetic energy, as he is now at the lowest point of the swing, and hence has no potential energy.

The kinetic energy at the top of the swing is (1/2)*m*(6.00 m/s)^2 and the potential energy at the top of the swing is m*g*h. We can write the height 'h' in terms of the length of the vine (31.0 m) and the angle it makes with the vertical, theta (42.0°), as h = L*(1 - cos(theta)) = 31.0 m*(1 - cos(42.0°)).

As mechanical energy is conserved, the sum of kinetic and potential energy at the top of the swing will equal the kinetic energy at the bottom of the swing, which we can write as (1/2)*m*v_f^2. Equating and simplifying gives us a value of v_f = sqrt(2*g*L*(1 - cos(theta))(2*9.8 m/s^2*31.0 m*(1 - cos(42.0°)))).

Popping these numbers into a calculator gives an answer of approximately 12.55 m/s. Hence, the closest answer, and the one we should choose, is (B) 12.5 m/s.

Answer

given,

time of travel = 2 hours

distance between the two car = 208 miles

one car traveled 8 miles per hour faster than other.

speed of both the car =?

Let speed of one car = x

speed of the second car = x + 8

distance = speed x time

distance = 2 x..............(1)

distance = 2(x+8)...........(2)

total distance = 208 miles

2 x + 2(x + 8) = 208 miles

2 x + 8 = 104

2x = 96

x = 48 mile/h (1st car)

x + 8  = 56 mile/hr(2nd car)

hence, speed of both the vehicle is given above.
