When a hard element is suspended from an axis and made to oscillate about that, then it is known as compound pendulum.
C = Initial position of center of mass
C' = Position of origin of mass after time t
S = Point of suspension
l = Displacement among point of suspension and center of mass (it remains same during motion)
A block goes on a wedge which in turns goes on a horizontal table, as given in figure. The wedge angle is Φ. As long as the wedge is in met with table, we have the trivial const

A 400kVA transformer has a primary winding resistance of 0.5Ω and a secondary winding resistance of 0.001Ω . The iron loss is 2.5kW and the primary and secondary voltages are
The atmospheric pressure at any position is numerically similar to the weight of a column of air of unit cross-sectional area extending from that position to the top of the atmosph
a ball is dropped from a bridge 122.5m high. after the ball has been falling for2 sec another is thrown straight downwards after it. the initial velocity of the ball is such that
According to de-Broglie theory, the wavelength of de-Broglie wave is given by Where h = Plank's constant, m = Mass of the particle, v = Speed of the particle, E = Energy of
Is this wavelength in vacuum? Answer; as per mass of CPH is constant, and Vc is for an alone CPH, so wavelength should be in vacuum, that there is not any gravity effect. But i
