Answer:0
Explanation:
Given
two particles of mass m and 3m
They move towards each other with velocity v
As the collision is Elastic therefore value of coefficient of restitution is 1
if and
are velocity of approach of m and 3 m
and and
are velocity after collision respectively
therefore
conserving momentum
Therefore velocity of heavier mass is zero
Explanation: Michelson-Morley experiment, an attempt to detect the velocity of Earth with respect to the hypothetical luminiferous ether, a medium in space proposed to carry light waves. First performed in Germany in 1880–81 by the physicist A.A. Michelson, the test was later refined in 1887 by Michelson and Edward W.
