A ball bearing falls through a viscous liquid(a) Using a labelled diagram of a tall vessel, show all the forces acting on it(b) When will it attain terminal velocity?

The horizontal component of the initial speed of a particle projected at 30° to the horizontal is 50 m\(^{-1}\). If the acceleration of free fall due to gravity is 10 ms\(^{-2}\), determine its;(a) initial speed;(b) speed at the maximum height reached.

In an electrolysis experiment, the ammeter records a steady current of 1 A. The mass of copper deposited in 30 minutes is 0.66 g. Calculate the error in the ammeter reading. [ Electrochemical equivalent of copper = 0.00033 g C\(^{-1}\)]

A wire gradually stretched by loading it until it snaps.(a) Sketch a load-extension graph for the wire(b) Indicate on the graph the(i) elastic limit (E);(ii) yield point (Y);(iii) breaking point (B).
