Answer:
The angle through which the wheel turned is 947.7 rad.
Explanation:
initial angular velocity, 
= 33.3 rad/s
angular acceleration, α = 2.15 rad/s²
final angular velocity, 
= 72 rad/s
angle the wheel turned, θ = ?
The angle through which the wheel turned can be calculated by applying the following kinematic equation;
Therefore, the angle through which the wheel turned is 947.7 rad.
There are three states of matter.
Ok, I think this is right but I am not sure:
Q = ϵ
0AE
A= π π
r^2
=(8.85x10^-12 C^2/Nm^2)
( π π (0.02m)^2)
(3x10^6 N/C) =3.3x10^-8 C = 33nC N = Q/e = (3.3x10^-8 C)/(1.60x10^-19 C/electron) = 2.1x10^11 electrons
<span>We can use a simple equation to calculate the increase in gravitational potential energy.
PE = mgh
m is the mass of the object
g is the acceleration due to gravity
h is the change in height
PE = mgh
PE = (3.75 kg) (9.80 m/s^2) (1.5 m)
PE = 55.1 Joules
The increase in gravitational potential energy is 55.1 Joules.</span>
