1) Find the dimension formula of,
Density / Pressure / Work / Energy / Power / Gravitational Constant / Momentum ?
2) To find the time period of a simple pendulum, its time period (t) may depend upon (i) mass (m) of the pendulum (ii) the length (l) and (iii) acceleration due to gravity (g).
3) Convert 1 dyne into Newton.
4) Convert 500 erg into Joule.
