Explanation:
An electrical circuit needs:
a source of electrical power (this could be a power plant or a battery)
a material along which the electricity can flow (this may be a copper wire)
something to power (this could be a bulb)
The circuit is connected in a loop. Then, the source of power pushes electrons around the wire. It lights the bulb and continues in the circuit until it is broken.
A simple circuit lights one bulb. More difficult circuits might have several switches and loops. This would allow different groups of lights to be turned on or off at the same time.

Answer:
The induced emf is 
Explanation:
From the question we are told that
The number of turn is 
The diameter of the coil is 
The uniform magnetic at initial is 
The uniform magnetic at initial is 
The time taken is
The angle the magnetic field makes with vertical is 
Generally induced emf is mathematically represented as

where
is the change magnetic flux
Magnetic flux is mathematically represented as


Substituting this above


Where B is the magnetic field and A is the area which is mathematically evaluated as

Substituting values


From the equation of emf

dB = 
So

substituting values


An inclined plane makes work easier by breaking an upward or downward movement into smaller increments.
A screw is like an inclined plane wrapped around a cylinder. It turns a small rotational force into a larger forward driving force
Answer:1 trip around the earth is an angular displacement of 2*pi
3.6525*10^2 days
I
Explanation:24 h/1 day * 3.600*10^3 s/1h = 3.156*10^7 s
Angular speed = angular displacement / time
Angular speed = 2*pi rads / 3.156*10^7 s = 1.9910*10^-7 rad/s
