The work you put into something is the energy it has afterward (neglecting friction and other so-called non-conservative forces).  This is called the work-energy theorem.  Think of objects in a gravitational field as "energy piggy banks".  If you put X joules of energy into it, that energy will be there as potential energy, stored for later.  So if you do 144J of work to elevate the bucket from an initial position, what ever it is initially, the final gravitational energy is 144J greater than before.

A coil is wrapped with 332 turns of wire on the perimeter of a circular frame (of radius 30 cm). Each turn has the same area, eq
almond37 [142]

Answer:

E=84.5V

Explanation:

From the question we are told that:

Number of Turns N=332turns

Radius r= 30cm

Field Change B=56mt-29mt=27mt

Time t=63ms

Generally the equation for Magnetic Field is mathematically given by

 \frac{dB}{dt}=\frac{27*10^{-3}}{29*10^{-3}}

 \frac{dB}{dt}=0.9T/s

Generally the Flux at 332 turns is  mathematically given by

 \phi=N*A*B

Generally the equation for Area of coil is mathematically given by

 A=\pi*r^2

 A=\pi*(r*10^{-2})^2

Since

 \phi=332*\pi*(\theta*10^{-2})^2*B

Therefore

 \frac{d \phi}{dt}=332*\pi*(900*10^{-4}*\frac{dB}{dt}

Generally the equation for emf Magnitude is mathematically given by

 E=\frac{d\phi}{dt}

 E=332*\pi*(900*10^{-4}*0.9

 E=84.5V
