Because the earth revolves around the sun and the whole earth isn’t always facing the sun it changes that’s why we have night and day and summer and winter etc
Hello!
Δv = 0.1 m/s
Use the equation F = m · a to solve for the acceleration:
5 = 15 · a
a = 1/3
The equation to solve for acceleration can be rewritten to solve for the change in velocity:
Δv / t = a
Δv = at
We are given the acceleration and time, therefore:
Δv = (1/3)(0.3)
Δv = 0.1 m/s
Answer:
The elevator must be moving upward.
Explanation:
During the motion of an elevator, the weight of the person deviates from his or her actual weight. This temporary weight during the motion is referred to as "Apparent Weight". So, when the elevator is moving downward, the apparent weight of the person becomes less than his or her actual weight.
On the other hand, for the upward motion of the elevator, the apparent weight of the person becomes more than the actual weight of that person.
Since the apparent weight (645 N) of the student, in this case, is greater than the actual weight (615 N) of the student.
<u>Therefore, the elevator must be moving upward.</u>
I believe it’s because of the air from the lower part of the mountain adjusting to the climate at the top. Mountains cause air to rise, and when that air rises it cools down creating the clouds.
Hope I helped!
