Answer:
Explanation:
Given
Temperature of the gas is increased from 100 to 200
Also we know that average kinetic energy of the molecules is

Where
R=Gas constant
=Avogadro's number
T=Temperature in kelvin

So kinetic energy increases by


It is B because the other ones are good.
I believe it is the first one
The speed is constant since there is no opposite force facing the car
That’s my best guest hope it helps !! :)
Because gravity is constant
<span>the only force acting in free-fall is gravity which points downward at 9.8 m/s</span>
