The moons volume is that of 2 percent of the earth.
Answer:
The initial velocity is 50 m/s.
(C) is correct option.
Explanation:
Given that,
Time = 10 sec
For first half,
We need to calculate the height
Using equation of motion
....(I)
For second half,
We need to calculate the time
Using equation of motion
Put the value of h from equation (I)
According to question,
Put the value of t₁ and t₂
Here, g = 10
The initial velocity is
Hence, The initial velocity is 50 m/s.
Explanation:
Below is an attachment containing the solution.
It is c convection because convection is when something is hot therefore less dense material to rise and cooler material to sink under the influence of gravity
