A single fixed pulley
Set up a one fixed pulley as shown in the diagram below. By means of weights see how much force is needed to lift weights of 25, 50, 75, 100 and 200 g. Calculate the distance moved by the effort force when the resistance force (the weight) is moved by 20 cm

At 200.0 K, silicon has 1.89 x 10 5 thermally liberated charge carriers/cm 3 . If it is doped with 1 As atom to 3.75 million Si atoms, what is the ratio of doped carriers to t
The idea that everything is made up of very small particles has been developed over many years supported by several experiments: (i) Brownian motion :
Define: Electric potential. The electric potential in an electric field at a point is define as the amount of work done in moving a unit positive charge from infinity to that
Capacitance: If we increase the voltage between the plates, the charge increases, but the ratio of charge to voltage remains the same. This ratio gives the capacitance (C) of
