Answer:

Explanation:
Initial angular speed of the ferris wheel is given as



final angular speed after friction is given as



now angular acceleration is given as



now torque due to friction on the wheel is given as



Now the power required to rotate it with initial given speed is


A = (Vf-Vi) / t,
a = (6-0)/3 = 2m/s^2,
F = ma = 2 * 2 = 4N
Answer:
I believe the correct answer is B..<u>" 1 "</u>
Explanation:
hope it helps! ;)
CONDENSATION is the process by which water vapor (gas) in the atmosphere turns into water (liquid state). It is the opposite of EVAPORATION.Cool temperatures are essential for condensation to happen, because as long as the temperature in the atmosphere is high, it can hold the water vapor and delay condensation. So the temperature in condensation rises.
Answer:
Faraday invented the electromagnetic rotation.
Explanation:
Faraday invented a device called electromagnetic rotation, Faraday got a rotation with magnetic force, he used a cable, mercury, and a magnet.
The cable would rotate around the magnet, this would be a beginning for the electromagnetic technology.
For example:
The Homopolar motor or called electric motor was created for Faraday's invention.
We can find electric motor in Washing machines, fans, turbines, even in motorcycles and electric cars.
