In longitudinal waves, the particles of the medium or a system displaces back and forth(parallel) in the direction of the propagation of waves. In transverse waves, the particles of the medium or a system displaces perpendicular to the direction of the propagation of waves. Therefore, C is correct.
The earth is made up of 3 layers,the crust,mantle,and core,but the largest is the mantle
Answer:
754.8 m
Explanation:
The centripetal acceleration is given by

where v is the speed of the airplane and r is the radius of the loop.
We can rewrite the speed of the airplane as the ratio between the length of the circumference (
) and the time taken:

Substituting in the formula of the acceleration, we have

Re-arranging the formula and putting the numbers of the problem into it, we can find the radius of the loop, r:

High pressure, because the more pressure, the less volume, so the atoms have to get closer together.
