How do scientist know that seismic waves can be either compressional or transverse

Answers

Answer 1
Answer: Hey there! 

Scientists know that seismic waves can be either compressional or transverse because there are horizontal and vertical movements during an earthquake. Horizontal movements are compressional while vertical movements are transverse. 

Thank you!

In the Bohr model of the hydrogen atom, an electron moves in a circular path around a proton. The speed of the electron is approximately 2.20 3 106 m/s. Find (a) the force acting on the electron as it revolves in a circular orbit of radius 0.529 3 10210 m and (b) the centripetal acceleration of the electron

Answers

The force of a particle moving in a circular motion is:
F=ma
where m is the mass and a is the centripetal acceleration, which is expressed as:
a=v²/r

where v is the speed and r the distance between the particles. You use these equations, by substituting the values given in order to solve  the problem.

A road with a positive cross slope is highest __________.

Answers

A road with a positive cross slope is highest in the center of the road.

The roads with Cross slopes are formed to provide the drainage system so that water will run off from the surface. Due to this no water stands on the roads, especially when there is heavy rain it is very useful. It is a very important safety factor.

Which explains how the Coriolis effect causes air circulation? A.
Air from the equator moves toward the poles faster than the ground below it, so friction causes the air to veer west. In contrast, air from the poles moves toward the equator slower than the ground below it, so friction causes it to veer to the east.
B.
Air from the equator moves toward the poles faster than the ground below it, so friction causes the air to veer east. In contrast, air from the poles moves toward the equator slower than the ground below it, so friction causes it to veer to the west.

Air from the poles moves toward the equator faster than the ground below it, so friction causes the air to veer east. In contrast, air from the equator moves toward the poles slower than the ground below it, so friction causes it to veer to the west.
D.
Air from the equator moves toward the poles slower than the ground below it, so friction causes the air to veer east. In contrast, air from the poles moves toward the equator faster than the ground below it, so friction causes it to veer to the west.

Answers

The right answer for the question that is being asked and shown above is that: "Air from the equator moves toward the poles faster than the ground below it, so friction causes the air to veer west. In contrast, air from the poles moves toward the equator slower than the ground below it, so friction causes it to veer to the east. "
