Metamorphic
Metamorphic rocks are formed under the surface of the earth from the metamorphosis (change) that occurs due to intense heat and pressure (squeezing).
Answer:
Explanation:
Given
Mass of first object 
Mass of second object 
Distance between them 
object is placed between them
So force exerted by
on 



Force exerted by 



So net force on
is



i.e. net force is towards 
(b)For net force to be zero on
, suppose
So force exerted by
and
must be equal








V=s/t. All you need to do is
s=v×t=330×1.8
Answer:
Option (D)
Explanation:
According to the nebula hypothesis that explains the formation of solar system, there occurs changes in terms of its shape as well as the rate of rotation. It is because of the conservation of angular momentum.
The total angular momentum comprising a system remains same or constant, throughout its period of rotation in the absence of net torque. Due to the increasing density, the nebula eventually collapses, and these clouds of gases collides with one another and forms a large cloud. These clouds attains an average velocity and results in an orderly motion, which eventually take the shape of a disk. This is how with time, the sun and the planets have formed, comprising the solar system.
Thus, the correct answer is option (D).
Actually moving and not. It is the sum of potential and kinetic energy.
