Answer: The electromagnetic waves reach Earth, while the mechanical waves do not.
Explanation:
Answer:
0.405 seconds
Explanation:
Consider the amount of time it takes the block to fall from 53 m up to 14 m above the ground; then consider the amount of time it takes the block to fall from 53 m up to 2 m above the ground.
First, d = (1/2) gt^2 or t= ( 2 d / g)^1/2
= ( 2 × 39 / 9.8)^1/2 = 2.8212 seconds
Then, to fall from 53 down to 2 meters...
d = (1/2) gt^2 or t= ( 2 d / g)^1/2
= ( 2 * 51/ 9.8 )^1/2 = 3.2262 seconds
So the amount of time it takes for the block to fall from 14 m upto 2 m above the ground
3.2262 - 2.8212 = 0.405 seconds
this is how much time there is from when the man sees the block until it hits him. Not much time...

Answer:
The amounts will stay the same.
Explanation:
We have a case here. O°C ice into O°C water in an insulated container. The poser here is that what would be the net effect.
It must be highlighted that the insulated container is parody of a constant room temperature and pressure. Meaning all factors are held constant.
Also, a O°C ice is simply the same as a O°C water. Hence, viewing the question under this context, and also acknowledging the constant environment, tells us that the two - Ice and Water at such temperature, will remain unchanged. The effect will be neural.
The underlying factor is that both substances are subjected to same conditions. Hence, the latent kinetic energy and other molecular movements that could occasion will be doing so at same level and frequency. Thus, producing a neutral or almost non different result.
