If force [F], acceleration [A] and time [T] are chosen as the fundamental physical quantities. Find the dimensions of energy.

If E and G respectively denote energy and gravitational constant, then E/G has the dimensions of

Taking into account of the significant figures, what is the value of 9.99m − 0.0099m?

The unit of thermal conductivity is.

The main scale of a vernier callipers has n divisions/cm. n divisions of the vernier scale coincide with (n-1) divisions of main scale. The least count of the vernier callipers is,

A physical quantity of the dimensions of length that can be formed out of c, G and  is [c is velocity of light, G is the universal constant of gravitation and e is charge].

If dimensions of critical velocity v_c of a liquid flowing through a tube are expressed as [η^xρ^yγ^z] where η, ρ and γ are the coefficient of viscosity of liquid, density of liquid and radius of the tube respectively, then the values of x, y and z are given by.

In an experiment four quantities a, b, c and d are measured with percentage error 1%, 2%, 3% and 4% respectively. Quantity P is calculated as follows
