Answer:
The shanghai maglev train is capable of reaching speeds of up to 217.48 in mph
217.48 mph
Explanation:
Answer:
The answer is
.
Explanation:
You are asking only for the total volume, so the important data here is the surface area of the earth's crust,

and the average thickness of the earth's crust,
.
Imagine that you can stretch the surface area as if it were a blanket, now if you want to calculate its volume, you just need to multiply its area by its thickness,
.

<u>Answer;</u></h3>
= 5.102 m
<h3><u>Explanation;</u></h3>
The total energy, i.e. sum of kinetic and potential energy, is constant.
That is; E = KE + PE
Initially, PE = 0 and KE = 1/2 mv^2
At maximum height, velocity=0, thus, KE = 0 and PE = mgh
Since, total energy is constant (KE converts to PE when the ball is rising).
Therefore, KE = PE
or, 1/2 mv^2 = mgh
or, h = v^2 /2g
= 10^2 / (2x9.8)
=<u> 5.102 m</u>
