Starting from rest, a disk rotates about its central axis with constant angular acceleration. in 5.0 it rotates 25 during that time, what are the magnitudes of a) the angular acceleration and b) the angular velocity after 5.0 c) without changing the angular acceleration, what additional angle will the disk turn during the next 5.0

a).

b).

c).

Explanation:

Using the equations for angular motion

a).

The initial position is zero as well as the initial speed so to know the angular accelerations replacing numeric

b).

The angular velocity can find knowing the distance it rotates for the time so far so:

c).

The additional angle will the disk turn during the next 5.0s is

Total time 10s however we want to know the additional so the difference os the distance in the total and the distance already have is the additional angle so:

So:

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

probably not if net force is zero
