Answer:

Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour. For air and marine travel the knot is commonly used.

Gas A has molecules with small mass. Gas B has molecules with larger mass. They are at the same temperature.

Julli [10]

Answer:

c)The gases have the same average kinetic energy.

Explanation:

As we know that the kinetic energy of gas is given as

$K = \frac{1}{2}mv^2$

here we know that

$v = \sqrt{\frac{3RT}{M}}$

so we have

$K = \frac{1}{2}m (\frac{3RT}{M})$

now we have

$K = \frac{3}{2}n RT$

now mean kinetic energy per molecule is given as

$K_{avg} = \frac{3}{2}KT$

so this is independent of the mass of the gas

so average kinetic energy will remain same for both the gas molecules

What happens to energy and matter when a wave moves through space?

vivado [14]

Answer:

energy can move from one location to another, the particles of matter in the medium return to their fixed position. A wave transports its energy without transporting matter.

The bending of light as it passes from one medium to the next is

S_A_V [24]

This is called refraction. Some common examples of refraction are a straw appearing bent or cut once it enters water in a glass.
