attashe74 [19]

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."

A ball rolls off a level table with a speed of 2.2 m/s. The table is 1.2 meters high. How far away from the base of the table do
r-ruslan [8.4K]

The base of table is "1.08856 m" far away from the ball land.

Given:

Distance travelled by ball,

  • S = 1.2 m

Initial velocity,

  • u = 0 m/s

Acceleration,

  • a = 9.8 m/s²

Constant speed,

  • 2.2 m/s

As we know the formula,

→ S = ut+\frac{1}{2}at^2

By substituting the values, we get

→ 1.2=\frac{1}{2}\times 9.8t^2

→ 1.2 = 4.9 t^2

→    t = \sqrt{\frac{1.2}{4.9} }

→      = 0.4948 \ seconds

Let,

  • Horizontal distance will be "x".
  • Time = t

→ x = 2.2\times t

     = 2.2\times 0.4948

     = 1.08856 \ m

Thus the solution above is right.
