Answer:
0.057 joules is needed to create the total rotational energy each second.
Explanation:
The energy rate is the ratio of total energy to time, which coincides with the definition of power at constant rate:




0.057 joules is needed to create the total rotational energy each second.
Answer:

34.46 V/m
Explanation:
= Vacuum permeability = 
c = Speed of light = 
I = Intensity = 1.575 W/m²
The maximum magnetic field intensity is given by

The magnetic field intensity is 
The maximum electric field intensity is given by

The electric field intensity is 34.46 V/m
Explanation:
Mass of the crate, m = 68 kg
We need to find the resulting acceleration if :
(a) Force, P = 0
P = m a
⇒ a = 0
(b) P = 181 N



(c) P = 352 N



Hence, this is the required solution.
Explanation:
We'll call the radius r and the diameter d:
We also assume that the riders are at a distance r = d/2 = 7m from the center of the wheel.
The period of the wheel is 24s. The tangent velocity of the wheel (and the riders) will be: (2pi/T)*r = 0.8 m/s (circa).
It means that in 3 minutes (180 seconds) they'll run 0.8 m/s * 180s = 144m.
Hopefully I understood the question. If yes, that's the answer.
