<u><em>Randomly disturbed is your answer.</em></u>
Answer:

Explanation:
= Mass of clay = m
= Mass of block = 3m
= Velocity of clay
= Velocity of block = -3 m/s
= Velocity of combined mass = -1 m/s
As mometum in the system is conserved we get

The original velocity of the clay mass was
.
Answer:
<h3>Questioned what might happen if CFCs rose into higher altitudes and stayed there for a longer period of time.</h3>
Explanation:
- Mario Molina noticed that Chlorofluorocarbons (CFCs) did not breakdown in lower atmospheric conditions unlike other chemicals released into the air. He observed that CHCs rose to higher altitudes where solar radiation were stronger.
- Through this observation, he questioned what might happen if CFCs rose into higher altitudes and stayed there for a longer period of time. This question led to the finding that the chlorine present in CFCs depleted the ozone layer which protects the earth from direct solar radiation.
- It helped in understanding the affects of CFCs to the environment and ozone layer which subsequently led to the ban and limitation on the use of CFCs altogether.
Answer:
migrant diffusion.
Explanation:
Migrant diffusion was the main mechanism by which folk customs spread to popular culture. Folk customs such as sports and music originated in small, limited regions that shared common cultural traits. Its global spread was limited by geographical and environmental barriers, as well as limited technology. Therefore, the main way in which these spread was through migrant diffusion. As people moved away from their places of origin, they took these traditions with them, spreading them to other areas of the world.
