Answer:
The molecules in hot air are moving faster than the molecules in cold air.
Answer:
6 m/s
Explanation:
Well we can find acceleration a=v/t = (21-0)/7=3 m/s^2
vf=at+v0, use this equation to solve for the vf
vf=3(2)+0=6 m/s was its speed at 2s
Answer:
Explanation:
speed of sound in 24 degrees celsius
345.48m/s
hence 345.48m/s x 3s = 1036.44m
Uhh it is used to detirmine heat
