A particle of mass m moves subject to a central force whose potential is V (r) = Kr3, K > 0. 1. For what kinetic energy and angular momentum will the orbit be a circle of radius a about the origin? 2. What is the period T of this circular motion? 3. If the motion is slightly disturbed from this circular orbit, what will be the period of small radial oscillations about r = a? Express through T. 1 {

d) physical means can be used to separate the components of air.

answer a fan shaped mass of sediment deposited at the base of a mountain front do to an abrupt change in stream gradient;

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
