Answer:

when the earth quakes...

Explanation:

or An earthquake is caused by a sudden slip on a fault,  When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.

The _____ of a wave is the number of wave cycles per second. this quantity is given the symbol ν and has units of s–1 or _____.
Fynjy0 [20]

The frequency of a wave is the number of wave cycles per second. this quantity is given the symbol ν and has units of s^–1 or hertz.

What is a wave ?

A wave is a dynamic disturbance of one or more quantities that propagates through time. When waves oscillate frequently around an equilibrium value at a certain frequency, they are said to be periodic.

What is a wave cycle ?

The wavelength is the measured distance in meters between two waves' peaks or troughs, which is referred to as a wave cycle. It's crucial to remember that the distance from peak to peak equals the distance from trough to trough. The length of time it takes a wave to complete one cycle is known as the wave's period.

State how the centripetal force is provided in the following
konstantin123 [22]

Answer:

a) a planet orbiting the Sun,

Explanation:

  • As the word centripetal force means the movement of the body towards the centers around to which it's moving. The force of gravity of the sun, moon, and sun all celestial objects enable them to attract other celestial bodies.
  • The bigger is the mass the bigger will force of attraction. Like the other planets in the solar system, the earth is also attracted to the sun and revolves around in its defined orbit in an elliptical path.

A car was traveling at a constant speed of 20m/s overcomes a constant frictional resistant of 300newton.. What is the horse powe
nadezda [96]

Answer:

8 hp

Explanation:

Power = work / time

P = W/t

Work = force × distance

W = Fd

Substituting:

P = Fd/t

P = Fv

Given that F = 300 N and v = 20 m/s:

P = (300 N) (20 m/s)

P = 6000 W

P = 6 kW

Converting to horse power:

6 kW × (1 hp / ¾ kW) = 8 hp
