What is Centrifugal Force?
Centrifugal force is the force that is equivalent in magnitude but opposite in direction to the centripetal force, which is the force directed toward the center of a rotating or revolving mass.
Think of it this way. Let's say you have a yo-yo and let it unwind. Then you begin swinging it around your head in a circle parallel to the ground. The force that keeps the yo-yo in its circular path is the centripetal force. Without it, the yo-yo would not continue in its circular path but would fly off in a straight line, which it is inclined to do. The tension in the string, the force that makes the string taut, is the centrifugal force.
Define Eddy Currents ? If you try to pull a solid piece of some metals (good electrical conductors) quickly between the poles of a strong magnet, you will feel a force pushing
The effects of back emf on circuit current: In proving the time constant, it was stated that, at the instant the switch is closed, the current (I) is zero. This is because, at

A 2350-kg granite tombstone absorbs 2.8 x 10 7 J of energy from the Sun to change its temperature from 5.0°C at night to 20.0°C during an autumn day. Verify the specific heat
Two wires on a piano are the same length and are pulled by the same tension. wire 1 vibrates at a frequency 1.5 times the frequency of wire 2. Calculate the ratio of their masses (
What are synthetic rubbers? Give the preparation and structure of any two synthetic rubbers.
In nuclear fusion two or more than two lighter nuclei join to form a single heavy nucleus. The volume of one molecule so formed is less than the sum of the masses of parent nuclei.
