When a satellite going round the eath in a circular orbit of radius r and speed V, loses some of its energy, then r and V change as
Detailed Solution for JIPMER Full Mock Test - 1 - Question 11

The total energy of a satellite in an orbit is giv... moreen by E=GMm/2R in magnitude. So when energy is lost R will decrease as it is obvious from the eqn. Moreover the kinetic energy of the satellite is given by K=GMm/2R. So when R decreases. the kinetic energy must increase and so does the velocity.The other way to look into the problem is that. when satellite is going round the planet. It's angular momentum i.e mvr must be constant about the centre of the orbit. so keep the same to a constant value. v must increase in order to compensate with the decrease in R.

If temperature of the sun were to increase from T to 2T and its radius from R to 2R, then how many times the radiant energy will be received on the earth?
Detailed Solution for JIPMER Full Mock Test - 1 - Question 14

From Stefan's law, the energy radiated by the sun is given by P=σeAT4,

Assuming e=1 for the sun.

In 1 st case, P1=σe × 4πR2 × T4

In 2nd case, P2 = σe × 4π(2R)2 × (2T)4

= σe × 4πR2 × T4 × 64 = 64P1

The rate at which energy received at the earth is,

where, AE = area of the earth, 

RSE = distance between the sun and the earth.

A U-tube contains water and methylated spirit seperated by mercury. The mercury columns in the two arms are in level with 18 cm of water in one arm and 20 cm spirit in the other arm. The density of spirit is (Density of water=1 g-cm-3)
Detailed Solution for JIPMER Full Mock Test - 1 - Question 27


For water column in one arm of U - tube
h1 = 18 cm, ρ1 = 1 gm cm-3
For spint column in other arm of U - tube
h2 18 cm, ρ2 = ?
If P1 and P2 be the pressures exerted by water column and spirit column respectively
Then P1 = h1 ρ1 g
and P2 = h2 ρ2 g
The mercury columns in the two arms of U-tube are at the same level, thus in equilibrium
P1 = P2
