Answer:

D) Spinning a coil of wire near a large magnet.

Explanation:

From Faraday's law of induction, when a conducting coil of wire is placed in changing magnetic flux, an emf is induced which produces current in the coil.

Induced emf is given by:

e = -\frac{d\phi}{dt}

A generator is based on the same principle.

The mechanical energy of rotating coil is converted to electrical energy when current is induced. Thus, the correct option is D) Spinning a coil of wire near a large magnet.

A person is standing on a spring bathroom scale on the floor of an elevator which is moving up and slowing down at the rate of 2
Alinara [238K]

Answer:

923.44N

Explanation:

Obviously Fn cannot equal Fg since the elevator is moving up  

Where Fn is the force read on the scale

Fg is gravitational force=mg=77.6 x 9.8=760.48N

So we use this equation:  

Fnet = Fn - Fg  

ma = Fn - mg

77.6 x 2.1 = Fn – 760.48

162.96N = Fn – 760.48N  

923.44 N = Fn

The answer is 923.44 N

daser333 [38]
Firstly, we must find the equation the speed, it can be obtained by the derivative of x =<span>x = 4.0t2 - 32t + 36, it means v= 8.0t-32. the particule stops means v= 0, and 0= 8.0t-32, which implies 8t=32, so t=4s, and then x(t=4) = 4.0(4)^2 - 32(4) + 36= - 28m
so x = - 28 m</span>
