Answer:

Explanation:
As we know that rms speed of ideal gas is given by the formula

here we know that

molecular mass of gas is given as

now from above formula we have

now we have

More force needs to be applied
Answer:
I need an image, but if you're talking about Potential and Kinetic energy, I will determine for you:
Explanation:
Potential Energy: stored energy that depends upon the relative position of various parts of a system.
Kinetic Energy: the form of energy that an object or a particle has by reason of its motion.
Therefore, if the skier is on top of the mountain, they would have potential energy since their energy from the ground to the top of the surface is stored. But, if the skier is in motion/mid-air from the top of a mountain, their energy is kinetic (in motion) because their stored energy (potential) is released as they step off of the surface.
answer: derived physical quantities are those quantities that are obtained from the basic physical quantities by multiplication or division and area is one of them
