The sound waves would not exsist in space because they is no sound in space
Explanation:
velocity of a freely falling body is given as
h= height and g= acc. due to gravity = 32ft/sec^2.
now, t secs the object at height of s feet its velocity
here u= initial velocity =0,
therefore,
Answer:
1. Hot air is less dense and has moved upward allowing cool air to move downward which is less dens
(Convection current)
2. The ceiling has transferred heat to him by radiation.
Explanation:
During the day when air is heated as a result of the ceiling transferring heat to it, it becomes less dens and it gains energy, which make it lighter in weight than cooler air, this hot air moves upward allowing cooler air to move downward.
If he keeps that pace he will be at the 34 yard line
