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.



5) Find the dimensions of the constants a and b in the Vander Waal's equation of state of a real gas 
        (P+aV2)(Vb)=RT.

Where, P = Pressure, V = Volume, R = Universal gas constant, T = Absolute Temperature.


6) Is dimensionally correct equation necessarily physically correct? What about the dimensionally wrong equation?



7) A student writes (R2GM) for escape velocity. Check the correctness of the formula by using dimensional analysis.


8) Find the dimensions of Planck’s constant (h) from the given equation: λ=hp; where λ is wavelength and p is the momentum of photon. 


9) Convert density of water 1 g/cm3 (CGS-system) into kg/m3 (MKS – system).


10) Check the correctness of the relation h=2TCosθrρg, Where symbols have usual meaning.
