Rocks within Earth both expand and contract as P waves pass
Explanation:
Rocks within the earth both expands and contracts as P-waves passes through them. P-waves are elastic waves.
- Elastic waves behaves in such a way that they do not cause permanent deformation of rocks.
- They can be said to cause elastic deformation when they travel through rocks.
- They simply temporarily expand and contract the rock within a short period by causing the vibration of particles of the medium.
- After a short while, the rock returns back to its original position as if nothing has happened to it.
- These elastic waves are better called seismic waves.
- P-waves are primary waves that can travel through any medium.

1250 J in 5 sec= 250 Joule(s) per second (1250/5 0
250 Joules per second = 250 Watts ( 1J/s = 1 Watt per definition)
250 Watts output = 250/0.65 efficiency = 384 Watts input
1 Horsepower = 732 Watts
Motors 1 Horsepower and under are made in certain step sizes like
3/4 , 1/2 , 1/3, 1/4, 1/16 1/20 of a Horsepower.
3/4 Horsepower is 549 Watts
1/2 Horsepower is 366 Watts
so you need to 3/4 horsepower motor to achieve 1250 J of work in 5 seconds.
False. because the object cannot freefall due to resistance, so it cannot develop full acceleration.
Together, normal and reverse faults are called dip-slip faults, because the movement on them occurs along the dip direction -- either down or up, respectively. Reverse faults create some of the world's highest mountain chains, including the Himalaya Mountains and the Rocky Mountains .
