An elevator ascends at a constant speed of 4 m/s, how much time is required for the elevator in order to travel 120 m upwards

We simply use the formula,

Given, velocity = 4 m per s and distance = 120 m.

Substituting these values, we get

.

Thus, required time for the elevator in order to travel 120 m upwards is 30 s.

Explanation:

e/c, where e is its total energy

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
