Answer:
It was generally believed that mountains were produced by vertical forces
Explanation:
The main view of the world worked geologically prior to the 1960s was that the mountains were formed by the vertical forces of nature.
The early people prior to 1960s believed in many different natural phenomenons and they give their own reasons for their occurrence. But later many researchers and geophysicists studied the formation of the earth and came with possible answers to these questions.
Thus the answer is
" It was generally believed that mountains were produced by vertical forces."
Answer:Racquet force is twice of Player force
Explanation:
Given
ball arrives at a speed of 
ball returned with speed of 
average Force imparted by racquet on the ball is given by

where 
time of contact of ball with racquet


When it land on the player hand its final velocity becomes zero and time of contact is same as of racquet


From 1 and 2 we get

Hence the magnitude of Force by racquet is twice the Force by player
