SPEED VELOCITY The distance travelled the body from its initial position to final position in one second is called speed. The displacement travelled by the body in one second is called velocity It...
A capacitor of unknown capacitance is connected across a battery of V volts. The charge stored in it is 360 pC. When potential across the capacitor is reduced by 120 V the charge stored in it becomes 120...
Dot or Scalar Product of Vectors Dot Product of two vectors A and B is defines as product of magnitude of the vectors and cosine of the angle between them. A•B = |A||B|CosT, Where T is the angle...
