The disk's average angular speed during those 5 seconds was
(1/2) (100 + 300) rad/s = 200 rad/sec
Spinning for 5 sec at an average angular speed of 200 rad/s, the disk turned
(200 rad/s) x (5 s) = <em>1,000 radians</em>
(That's 500/pi revolutions = roughly 159.2 revolutions.)
Answer:
As a boy, Sir Isaac Newton was fascinated by a Windmill.
A drawing of a Windmill, which many believe to have been sketched by the young Newton over three an half centuries ago was discovered in his childhood home on a wall.

A :-) A.a.) Given - u = 0.00 m/s
v = 10.0 m/s
t = 1.5 sec
m = 75 kg
Solution -
a = v - u by t
a = 10 - 0 by 1.5
a = 10 by 1.5
a = 6.6 m/s^2
A.b.) sorry ! I don’t no how to do this question
Answer:
The electrical field in the region between the plates is 10,000 V/m.
Explanation:
Given;
potential difference between the two parallel plates, V = 100 V
distance between the two parallel plates, d = 1 cm = 0.01 m
The electrical field in the region between the plates is given as;
E = V / d
where;
E is the electrical field in the region between the plates
E = (100) / (0.01)
E = 10,000 V/m
Therefore, the electrical field in the region between the plates is 10,000 V/m.
