If you want to know how energy will move between two objects, what do you
need to know about the objects?

A. Their densities
B. Their heats

c. Their temperatures
D. Their states

Answer:

0.5 kg

Explanation:

The momentum of an object is defined as

p = mv

where

m is the mass

v is the velocity

In this problem we have,

v = 15 m/s is the velocity of the stone

p = 7.5 kg m/s is the momentum

Solving for m, we can find the mass of the stone:

[tex]m=\frac{p}{v}=\frac{7.5 kg m/s}{15 m/s}=0.5 kg[/tex]

Data:

p = 7.5kg-m/s

v = 15m/s

m = ?

Explanation:

P = m×v

m = P/v

m = 7.5/15

m = 0.5kgs

Answer:

Photosynthesis

Light energy from the sun  stimulates photosynthesis by green plants. One major component of the carbon cycle is the reduction of the carbon (IV) oxide content in the atmosphere by plants. Plants take in Carbon (IV) oxide to use during the process of making their own food. During this process light energy is absorbed by chlorophyll and is used to convert carbon (IV) oxide and water to glucose.

This glucose is used during respiration by living organisms that give out carbon (IV) oxide. The cycle continues.

Answer:

v = 1630 m/s

T = 5.78 x 10^5 s

Explanation:

The tangential speed of the satellite can be found by requiring that the gravitational force on the satellite is equal to the centripetal force:

[tex]G\frac{Mm}{(R+h)^2}=m\frac{v^2}{R+h}[/tex]

where

G is the gravitational constant

M=5.97 x 1024kg is the Earth's mass

m is the satellite's mass

[tex]R=6.38 \cdot 10^6 m[/tex] is the Earth's radius

[tex]h=1.44\cdot 10^8 m[/tex] is the altitude of the satellite

v is the speed of the satellite

Solving for v,

[tex]v=\sqrt{\frac{GM}{R+h}}=\sqrt{\frac{(6.67\cdot 10^{-11})(5.97\cdot 10^{24}kg)}{6.38\cdot 10^6 m+1.44\cdot 10^8 m}}=1627 m/s \sim 1630 m/s[/tex]

And the period of the orbit is equal to the ratio between the distance covered during one revolution (the circumference of the orbit) and the speed:

[tex]T=\frac{2 \pi (R+h)}{v}=\frac{2\pi (6.38\cdot 10^6 m+1.44\cdot 10^8 m)}{1630 m/s}=5.79\cdot 10^5 s[/tex]

So the correct answer is

v = 1630 m/s

T = 5.78 x 10^5 s

Explanation:

A typical refrigerator door is made of steel or aluminum and not by iron. Similarly, the exterior cabinet also made of aluminum metal.

The outer cabinet and door, the inner cabinet or liner, the insulation placed between the two, the cooling system, the refrigerant, and the fittings make up the majority of modern refrigerators. Aluminum or steel sheet metal that has occasionally been preprinted is used to make the cabinet and door.

Typically, the metal is bought in a coil and supplied either straight into the production process or chopped to size and fed in sheets. Like the outside cabinet, the inside cabinet is built of sheet metal or plastic.

Fiberglass or polyfoam insulation is used to fill the space between the inner and exterior cabinets. Aluminum, copper, or an alloy is used to make the compressor, condenser, coils, and fins of the cooling system.

B. During reflection, rays stay in the original medium, and during refraction, rays pass into a new medium.

Explanation:

Trust me bro.

B. During reflection, rays stay in the original medium, and during refraction, rays pass into a new medium describes how rays behave when they travel through media during reflection and refraction.

Rays change direction as they reflect off the surface, move from one transparent medium to another, or pass through a medium whose composition is constantly changing.

Reflection involves changing the direction of the wave as it bounces off the barrier. Refraction of a wave involves changing the direction of the wave as it transitions from one medium to another. The refraction or curvature of a wave path involves changes in wave velocity and wavelength.

Just confirming

Q = 3.973x10⁻⁷C.

The key to solve this problem is using the equation of a parallel plate capacitor.

C = Q/Vᵃᵇ = ε₀ A/d Where C is the capacitance, Q is the charge placed on the plates, Vᵃᵇ is the potential difference between the plates, ε₀ is the constant of the permittivity of vacuum, A is the area of the plates, and d is the separation of the plates.

Clear Q from the equation Q/Vᵃᵇ = ε₀ A/d:

Q = ε₀AVᵃᵇ/d

With ε₀ = 8.85x10⁻¹²F/m, A = 5.10x10⁻³m², Vᵃᵇ = 125.00V, and d = 1.42x10⁻⁵m

Q = (8.85x10⁻¹²F/m)(5.10x10⁻³m²)(125.00V)/1.42x10⁻⁵m = 3.973x10⁻⁷C

Answer: A. Object A will have a positive charge.

Explanation: If the number of protons and electrons are the same, their net charges cancel each other out, and you have a neutral charge. If electrons are transferred to another object, the amount of positive charge will outweigh the amount of negative charge. As a result, you are left with an overall positive charge in object A. Meanwhile, object B is now negative.

Final answer:

When electrons are transferred from object A to object B, object A will become positively charged (option A) due to the loss of negatively charged electrons. This makes the answer A. Object A will have a positive charge.

Explanation:

If some electrons are transferred from object A to object B, the correct answer is A. Object A will have a positive charge. This is because electrons have a negative charge, and removing them from an object leaves that object with an excess of positive charge in the form of protons (which are positively charged and present in every atom). Object B, receiving the electrons, will become negatively charged since it gains additional negative charges.

Answer:D.International Space Station

Explanation:

The only one still in space

Answer: D. International Space Station

Explanation: The International Space Station is currently orbiting Earth.

Answer:

8.57 m

Explanation:

To solve the problem, we have to decompose the two vectors along the two directions first:

Vector A:

- x component: Ax = +9.66 m

- y compoment: Ay = 0 (the vector lies along the x-axis)

Vector B:

- x component: [tex]B_x = -(12.0 m) cos 45^{\circ}=-8.49 m[/tex]

- y component: [tex]B_y = (12.0 m) sin 45^{\circ}=8.49 m[/tex]

So now we can find the sum of the two vectors by adding the components along each axis:

[tex]R_x = A_x + B_x = 9.66 m - 8.49 m = 1.17 m[/tex]

[tex]R_y = A_y + B_y = 0 + 8.49 m = 8.49 m[/tex]

And the magnitude of the sum is given by Pythagorean theorem:

[tex]R=\sqrt{R_x^2+R_y^2}=\sqrt{(1.17 m)^2+(8.49 m)^2}=8.57 m[/tex]

To find the magnitude of the sum of two vectors, you add their magnitudes if they're in the same direction. Given the vectors are 12.0 m at 45.0° and 9.66 m (undirected), assuming the same direction, the magnitude of the sum is 21.66 m.

In this problem, we're dealing with vector addition in Physics, specifically calculating the magnitude of the sum of two given vectors. Given that the first vector has a magnitude of 12.0 m at an angle of 45.0°, and the second vector has a magnitude of 9.66 m (with no specific direction provided), we can use the principle of vector addition to find the resultant vector.

In the absence of the direction of the second vector, let's presume it's following the same direction for simplicity. The sum of these vectors (or the resultant vector) can be obtained by adding the magnitudes of the two vectors since they are in the same direction. So, the magnitude of the resultant vector is 12.0 m + 9.66 m = 21.66 m.

If the second vector was in a different direction, we would have to decompose the vectors into their horizontal and vertical components, add these components separately, and then calculate the magnitude and direction of the resultant vector using trigonometric principles.

Answer:

218.5 N

Explanation:

In order for the sled to be in equilibrium along the vertical direction, the forces acting along this direction must be balanced. So the equilibrium equation is:

[tex]N+F sin \theta - mg =0[/tex]

where

N is the normal force

F = 50 N is the force that pulls the sled

[tex]\theta[/tex] is the angle between the force and the horizontal, so

[tex]F sin \theta[/tex] is the component of F acting along the vertical direction

(mg) is the weight of the sled, with

m = 25 kg being the mass of the sled

g = 9.8 m/s^2 is the acceleration due to gravity

Solving the formula for N, we find

[tex]N=mg-F sin \theta = (25 kg)(9.8 m/s^2)-(50 N)sin 32^{\circ}=218.5 N[/tex]

By resolving into y - component, the normal force acting on the sled is 218.5 N.

Force is the product of mass and acceleration. Where a frictional force is negligible, the resultant force will be equal to the force applied.

Given that Jake drags a sled of mass 25 kg across the snow. The sled is attached to a rope that pulls with a force of 50 N at an angle of 32 degrees.

If g is taken to be 9.8 m/s^2, the forces acting on the mass are:

The weight mg = 25 x 10 = 245 N

The normal reaction N = ?

The applied force F which can be resolved into x and y components

x - component = 50 x cos 32 = 42.4N

y - component = 50 x sin 32 = 26.5 N

If there is no friction, the normal force acting on the sled can be calculated by resolving all the forces into x and y component.

By resolving into y - component,

N + 26.5 = 245

N = 245 - 26.5

N = 218.5 N

Therefore, the normal force acting on the sled is 218.5 N.

"Wave 3 resulted from constructive interference and Wave 4 resulted from destructive interference."

Explanation:

Constructive Interference:

When two waves meet in such a way that their crests line up together, then it's called constructive interference. The resulting wave has a higher amplitude.

Destructive Interference:

In destructive interference, the crest of one wave meets the trough of another, and the result is a lower total amplitude.

The amplitude of Wave 3 is higher than both the Waves, 1 & 2, so it must be a result of constructive interference.

The amplitude of Wave 4 is less than both the Waves, 1 & 2, so it must be a result of destructive interference.

In the absence of air resistance, projectiles exhibit accelerated vertical motion due to gravity and constant horizontal motion, as there is no horizontal force acting upon it.

Assuming no air resistance, all projectiles exhibit C) accelerated vertical motion and constant horizontal motion.

In physics, the motion of a projectile under gravity is divided into two components: vertical and horizontal. The vertical motion of a projectile is influenced by the force of gravity, which causes a constant acceleration downwards. This is why when a projectile is launched, it moves upwards slowing down until it reaches a peak, and then accelerates downwards as it falls. The force of gravity does not affect the horizontal motion, which remains constant assuming no air resistance.

https://brainly.com/question/20627626

#SPJ11

Final answer:

The answer is C) accelerated vertical motion and constant horizontal motion, due to gravity's constant acceleration acting vertically and no horizontal forces acting after launch.

Explanation:

The correct answer to the student's question is C) accelerated vertical motion and constant horizontal motion. In projectile motion, assuming no air resistance, the horizontal component of the motion has a constant velocity because there is no force acting in the horizontal direction once the object is in flight. However, the vertical component is influenced by the constant acceleration due to gravity (9.80 m/s2 downward). Thus, the vertical motion of a projectile is always accelerating downward at a constant rate, while the horizontal motion proceeds at a constant velocity.

One way to think about this is to imagine throwing a ball forward; the ball will move horizontally at the speed you threw it (ignoring air resistance) but will also begin to fall vertically due to gravity. This results in a characteristic parabolic motion, which is a path that the projectile follows under the influence of only constant gravitational acceleration.

Where’s the old gang?

Newton's first law of motion states that an object in motion will continue to move at a constant speed in a straight line unless acted upon by an external force. So, not all objects in motion require a force to keep them in motion.

According to Newton's first law of motion, an object in motion will continue to move at a constant speed in a straight line unless acted upon by an external force. So, it is not true that any object in motion must experience a force to keep it in motion. The force is only necessary to change the object's state of motion, such as slowing it down or altering its direction.

For example, imagine a hockey puck sliding on a frictionless ice rink. Once given an initial push, the puck will continue moving at a constant speed in a straight line until it encounters an external force, such as contact with the boards or another player.

Therefore, I disagree with the student's claim. An object in motion does not necessarily need a force to keep it in motion, but rather a force is required to change its state of motion.

Answer:

1,350 J

Explanation:

According to the work-energy theorem, the work done equals the change in kinetic energy.  So W = 1,350 J.

A 60.0 kg runner is moving at 6.00 m/s and speeds up to 9.00 m/s. Hence, The work done on the runner is 810 J.

Given:

ΔKE = 1,350 J

The change in kinetic energy (ΔKE) is equal to the work done on the runner (W).

ΔKE = W

Given:

ΔKE = 1,350 J

ΔKE = KE(final) - KE(initial)

KE(initial) = (1/2) × m × (initial velocity)² =  (1/2) × 60.0 × (6.00)² =  540 J

KE(final) = (1/2) × m × (final velocity)² = (1/2) × 60.0 × (9.00)² =  1,080 J

Now, we can find the work done is:

ΔKE = KE(final) - KE(initial)

1,350 = 1,080 - 540 + W

1,350= 540 + W

W = 810 J

Therefore, the work done on the runner is 810 J.
