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.
Q. (a) A giant refracting telescope at an observatory has an objective lens of focal length 15m. If an eyepiece of focal length 1.0 cm is used, what is the angular magnification o
a) A positive point test charge q 0 is placed at the midpoint p among the two equal positive charges q. What forces acts on it at or near this point p? b) Two charges 1X10 -
average or mean value of AC

what is zener diode?
Coulomb: Coulomb is the fundamental unit of charge. It is explained as the charge required to obtain 9?109 newton of force among two equal charges separated at a distance of one m
Why because it is not a source as Li-ion battery. If we want to measure the voltage(build in voltage) with in the diode we have to use the external source. We can''t directly measu
