The diagram above illustrates three forces T\(_1\), T\(_2\) and 100N in equilibrium. Determine the magnitude of T\(_1\).

An iron rod is moved from the earth to the moon. Which of the following properties of the rod would remain unchanged? i. mass ii. weight iii. relative density

A uniform cylindrical hydrometer of mass 20g and cross sectional area 0.54cm2 floats upright in a liquid. If 25cm of its length is submerged, calculate the relative density of the liquid. (Density of water = 1 gcm-3)

The apparent weight of a body wholly immersed in water is 32N and its weight in air is 96N. Calculate the volume of the body. (Density of water = 1000kgm-3, g = 10ms\(^{-2}\))

A wooden block of mass 1.6kg rests on a rough horizontal surface if the limiting friction force between the block and the surface is 8N. Calculate the coefficient of friction. (g = 10ms-2)
