Out of the choices given, the best choice to explain the direction of the moving force of air is from area o high pressure to areas of low pressure. The correct answer is B.
UV Radiation since it has a higher frequency than the others. The higher the frequency the shorter the wavelength.
The answer is true.
All object at any temperature emit radiant energy.
Answer:
6 N
Explanation:
= Mass flow rate = 1 kg/s
v = Final velocity = 6 m/s
u = Initial velocity = 0 m/s
Force is obtained when we divide change in momentum by time

The force the person exert on the extinguisher in order to prevent it from accelerating is 6 N
