Two satellites of equal masses, which can be considered as particles, are orbiting the earth at different heights. Will their moments of inertia be same or different?

Write down the difference between mass and moment of inertia.

Two solid spheres of the same mass are made of metals of different densities. Which of them has a larger moment of inertia about a diameter?

Should the speed of two artificial satellites of the earth having different masses but the same orbital radius, be the same?

Two liquids of equal mass and different densities p_1 and p_2 are mixed, what is the density of the mixture?

Two artificial satellites, one close to the surface and other away are revolving around the earth. Which of them has larger speed?

Two masses one n times heavier than the other are dropped from same height. How do their momentum compare just before they hit the ground.

Name the different forms of energy which can be obtained from seas and oceans.

Two solid sphere of the same mass and same radius, one solid and other hollow. Which one have greater moment of inertia about a diameter?

Two particles-one of mass m1, and the other of mass m2, carry equal charges. After being accelerated through the same potential difference they enter a region of uniform magnetic field and describe circular paths of radius (r_1) , and (r_2) , respectively. Find the ratio of their masses.
