1. For a gas if p and v denote the co-efficient of volume expansion at a constant pressure and coefficient of pressure at a constant volume respectively, then(adsbygoogle = window.adsbygoogle || []).push({});

1)p>v 2)p<v 3)p=v 4)p=0 and v=0

2. The horizontal component(H), vertical component (V) and total intensity (I) of the earth's magnetic field are related as ______________.

3. A current of 50 mA flows for 0.5 hours through an electric circuit, the number of electrons which will dift in the circuit will be? (Charge on one electron= 1.6*10^-19 C)

4.Work done in moving a charge of 2 coulomb from a point at 118 volt to a point at 128 volts will be _____________

My answers

1. p=v

2. I^2=V^2+H^2

3. whatdoes "mA" mean?

4. W=F*d; how can we find it out in this case?

I am not aware about these questions. Please tell me the solutions and some tutorials of relevant opics. Thanks a lot!!!!!!
