The volume of the lung 0.0024m^3 following exhalation and the pressure is 101.70KPa. Calculate the volume of the lungs during inhalation if the pressure falls to 84.16KPa

Given that:

kinetic energy of an object (K.E) = ?

mass of the object (m) = 30 Kg ,

velocity of object (v) = 20 m/s,

We know that,

Kinetic energy is a form of energy, that an object as by reason of its motion.

mathematically,

      The kinetic energy of the object (K.E) = 1/2 . (m. v²)

                                                                         = 1/2.(30 × 20²)

                                                                         = 6000 Joules

                                                                K.E = 6000 J or 6 KJ

The kinetic energy of the object is 6000 Joules

Units ;    N.m = J  (energy measured in Joules)

           KN.m = KJ

Answer:

Kinetic energy of the given object is 6000 J or 6 KJ.

Explanation:

We are given:

mass of the object = 30 kg; and

velocity with which the object moves = 20 m/s.

We know the formula of the kinetic energy:

Kinetic energy = 1/2 × mv[tex]^2[/tex]

Substituting the given values in the above formula to get:

Kinetic energy of object = 1/2 × 30 × 20[tex]^2[/tex] = 6000 J or 6 KJ

Let the initial velocity be u = 23 m/s

Let the final velocity be v.

Vehicle stops finally, therefore v = 0 m/s

Here during the braking, vehicle decelerates with constant acceleration,  thus the change in velocity is linear from initial velocity to final velocity.

for the Given condition:

Write the expression for the average speed [tex]V_{avg}[/tex]

[tex]V_{avg} =  \frac{u+v}{2}\\[/tex]

Substitute the values in the above expression.

[tex]V_{avg} = \frac{23+0}{2}\\              = 11.5 m/s[/tex]

Hence, the average speed during braking is 11.5 m/s

To calculate the distance to a star, astronomers observe it from different places along Earth's orbit around the Sun. If they measure the object's position several months apart, their "two eyes" will have a separation of well over 100 million miles!

B) The forces pointing in and down are balanced 

300n on the top and 300n on the bottom results in it being balanced

In the given diagram, the forces pointing up and down are balanced since they are equal in magnitudes and will cancel each other in magnitude.

Force acting on an object is able to deform it or to change its state of motion or rest. Force is a vector quantity and is characterised by its magnitude and direction.

When two same or different forces are acting in the same direction on an object, the resultant force will be the sum of magnitude of the two forces. If two forces are acting in the opposite directions, they will cancel each other in magnitudes.

In the given diagram, the force acting up and down are equal thus, they will cancel each other and is said to be balanced. The net force to the right direction is 200 N since 200 from 400 N is cancelled by the force with 200 N leftwards. Hence, option b is correct.

Ohms law: This law relates voltage difference between two points. Mathematically, the law states that V=IR;

                Where

                          V = voltage difference ; in volts

                          I = Current ; in Amperes

                          R = Resistance ; in ohms

1. Answer : given that R = 10 ; V= 12 V ;  I = ?

From ohms law,    I = V/R

                                = 12/10

                                = 1.2 Amp.

2. Answer:  given that R = 10 ; V= ? ;  I = 5

From ohms law,    V = IR

                                 = 10×5 = 50 V

3 . Answer:  given that R = ? ; V= 120 ;  I = 5

From ohms law,    R =  V/I

                                 = 120/5

                                 = 24 Ω

4 . Answer:  given that R = ? ; V= 10 ;  I = 20

From ohms law,    R =  V/I

                                 = 10/20

                                 = 0.5 Ω

5 . Answer:  given that R = 480 ; V= 24 ;  I = ?

From ohms law,  I =  V/R

                              = 24/480

                              = 0.05 A

6. Answer:  given that R = 150 ; V= ? ;  I = 1

From ohms law,  V = IR

                               = 1 × 150

                               = 150 V

Acceleration = (change in speed) / (time for the change)

Change in speed = (speed at the end) - (speed at the beginning).

Change in speed = (10 m/s) - (zero) = 10 m/s

Time for the change = 3 sec

Acceleration = (10 m/s) / (3 sec)

Acceleration = (3 and 1/3) m/s²  or 3.333 m/s²

To calculate the acceleration, use the change in velocity divided by the time. For an object going from rest to 10 m/s in 3 seconds, the acceleration is 3.33 m/s².

The question addresses the calculation of acceleration of an object in motion. To find the acceleration, we can use the formula:

Acceleration (a) = Change in velocity (omenclature) / Time (t)

In this scenario, the object goes from rest (initial velocity, u = 0 m/s) to a final velocity (v) of 10 m/s in a time (t) of 3 seconds.

Thus, acceleration (a) is calculated as:

a = (v - u) / t

a = (10 m/s - 0 m/s) / 3 s

a = 10 m/s / 3 s

a = 3.33 m/s²

The acceleration of the object is therefore 3.33 m/s².

The only correct statement on that list is choice-C:  If a positively charged rod is brought close to a positively charged object, the two objects will repel.

Answer:

C. If a positively charged rod is brought close to a positively charged object, the two objects will repel.

Explanation:

According to coulomb's law, the magnitude of the electric force between two point charges at rest is directly proportional to the product of the magnitude of both charges and inversely proportional to the square of the distance that separates them. This force is repulsive for like charges and attractive for opposite charges.

Correct answer: Warm air from the south rises.

The de Broglie wavelength of rubidium atoms at 0.20 µK can be found using the de Broglie equation after determining the atoms' momentum, which involves calculating their velocities at the given temperature. Since the temperature is extremely low, the de Broglie wavelength will be relatively large.

The student is seeking the de Broglie wavelength of rubidium atoms cooled to 0.20 µK in an atom trap. To find the de Broglie wavelength, we must first calculate the momentum of the atoms, which can be done using the temperature and kinetic theory to find the velocity and then the momentum, assuming nonrelativistic speeds. The de Broglie wavelength (λ) is given by the equation λ = h/p, where h is Planck's constant and p is the momentum of the particle.

Without knowing the exact mass of rubidium or its velocity at this temperature, we cannot calculate the specific wavelength. However, since the temperature is very low, we can expect the wavelength to be relatively large compared to what it would be at higher temperatures due to the inversely proportional relationship between momentum and wavelength.

Answer:

Its state is in uniformly accelerated motion

Explanation:

When an object is acted upon the force of gravity only, we said that the object is in free fall.

According to Newton's second law of motion:

[tex]F=ma[/tex]

where F is the net force on an object, m is its mass, a its acceleration, when the net force on an object (F) is non-zero, than the object accelerates (because a is non-zero), so the object is in accelerated motion.

In case of free fall, the rate of acceleration of the object is equal to [tex]g=9.8 m/s^2[/tex], the acceleration due to gravity, and it is constant. So, the object is moving by uniformly accelerated motion.

Answer:

B. Become a white dwarf star.

Explanation:

As the Sun is a medium size star in mid of its life of around 10 Billion years. When it will exhaust all the Hydrogen in the core, it will go through a long process of death: Converting into a red giant to Planetary Nebula to a white dwarf. It will spend trilliion of years in white dwarf phase before fading and converting to a Black dwarf.

If it had been a massive star it would have made a Supernova and then ultimately a black hole or a neutron star.

Our sun, a medium-sized star, will eventually turn into a white dwarf once its hydrogen fuel is exhausted. This is following the standard stellar evolution process. However, larger stars may explode as a supernova or form a black hole.

Our Sun is a star of average mass and will follow the stellar evolution process of stars in its mass range. It is predicted that once it exhausts its hydrogen fuel, it will eventually expand into a red giant and subsequently shed its outer layers, leaving behind a star core. This star core will shrink under its own gravity and become a white dwarf star.

In contrast, stars significantly larger than the Sun can explode in a spectacular event known as a supernova. Very massive stars have the potential to collapse under their own gravity and form a black hole.
