Answer:In a generator, current is produced in the armature winding. Ceiling fans, cars, etc. are all examples of motor. In power stations, generator is used to generate electricity.
Answer:
12.5 m/s North/east
Explanation:
I thought of it as a graph. I basically just found the distance between the points (0,0) and (10, 7.5)!
The formula for the time period oscillation of a spring is:
T = 2π√(m/k) where m is the mass of the object attached to the spring and k is the spring constant of the spring.
Multiplying m by 4 we have:
2π√(4m/k)
= 2π x 2√(m/k)
or 2 x (2π√(m/k)) or 2T.
Therefore, when object is four times as massive, then period will double.
Answer:
1.98 rad/s
Explanation:
Given that a spring stretches at a distance 
0.1 m when a mass of 0.5 kg is attached to it.
The angular velocity 
If it is stretched 0.2 m from the equilibrium length; we have:
The maximum velocity v = 0.2 × 9.9
v = 1.98 rad/s
Therefore; the maximum velocity of the mass = 1.98 rad/s
