Explain Centripetal force??
Sir Isaac Newton suggested that motion in a straight line is most natural, and that deviations from this type of motion are caused by a force pulling the body absent of line. When the force acts on the body from a fixed point, like a body moves in a circle, and the force towards the centre is known as a centripetal force.
An object that is 24 cm from a convex lens produces a real image that is 13 cm from the lens. What is the focal length of the lens?
How is that circuit wont be broken even there is an air gap in between the parallel plates? Ans) In AC circuit capacitor offers resistance to current as aresistor would do in DC.
Q. An aircraft having awing span of 10 m flies at a speed of 720 kmph. If the vertical component of the earth's magnetic field is 3 X 10 -5 T, calculate the emf induced between th
In a non-uniform magnetic material, these substances move from stronger parts of the field to the weaker parts.why?
