<h2>
Angular acceleration is 80 rad/s²
</h2><h2>
Number of revolutions undergone is 1.02</h2>
Explanation:
We have equation of motion v = u + at
Initial angular velocity, u = 0 rad/s
Final angular velocity, v = 32 rad/s
Time, t = 0.40 s
Substituting
v = u + at
32 = 0 + a x 0.40
a = 80 rad/s²
Angular acceleration is 80 rad/s²
We have equation of motion s = ut + 0.5 at²
Initial angular velocity, u = 0 rad/s
Angular acceleration, a = 80 rad/s²
Time, t = 0.4 s
Substituting
s = ut + 0.5 at²
s = 0 x 0.4 + 0.5 x 80 x 0.4²
s = 6.4 rad
Angular displacement = 6.4 rad
Number of revolutions undergone is 1.02
Balanced Forces are different from Unbalanced Forces because Balanced Forces are two forces acting in opposite directions of an object, and equal in size.On the other hand unbalanced forces are forces that cause a change in the motion of an object.
This impacts motion because when balance forces enter,... the object either stops (Stays at rest or moves at the same speed and direction) Unbalanced Forces causes an object to move faster/slower (might change the direction),.. due to one side having more force than the other.

Answer:
Taking water and oxygen from Earth is rather expensive and hard to do.
Explanation:
Without water and oxygen, travel to other planets is basically impossible
The voltage transformation is in direct proportion to the ratio of the turns in each winding. To transform 240 volts to 120, the secondary needs 25 turns.
