Explanation:
Let N be the number of turns in a circular loop having a radius of r₀ and a resistance R. The magnetic field is given by :

The induced emf in the circular coil is given by :

Where




Power dissipated is given by :



Energy dissipated in the circuit is given by :




Hence, this is the required solution.
Answer:
0 N/C
Explanation:
Parameters given:




The distance between
and
is

Electric field is given as

r = 15/2 = 7.5cm = 0.075m
The electric field at their midpoint due to
is:

= 
The electric field at the midpoint due to
is:

= 
The net electric field will be:
E =
+ 
E =
+ 
E = 0 N/C
BIg, big questions in Thermodynamics. ...
Not without "help" it can't. There are two versions of this. One is that it is impossible to take heat from something and convert it completely into work - there has to be some waste at a lower temperature. The other is that heat will not "spontaneously" go from a colder place to a warmer place. So, a domestic fridge needs a device to transfer the heat, that's that buzzing sound of a motor driving a refrigerant round in a cycle, taking heat out the fridge and making the surrounding warmer. It's also called a heat pump. The area near where the pump puts its heat can be felt to be warm.
