Explanation:
Using kinematics,
t = 4s
u = 0m/s
a = 9.8m/s^2
Therefore v = u + at = 0 + (4)(9.8) = 39.2m/s.
False The atmosphere's general circulation actually depicts the air flow around the world, not just an average.
<h3>What is global circulation in general?</h3>
The necessary transportation of heat from tropical to polar latitudes is performed by a system of winds that is known as the global circulation. Hadley cell, Ferrel cell, and Polar cell are the three cells in each hemisphere where air flows across the whole depth of the troposphere.
<h3>What type of nighttime air circulation pattern is typically linked with coastlines?</h3>
The wind turns around and blows out over the ocean at night because the land cools more quickly than the water. This is known as a land breeze. Additionally, the sun's rays have an impact on large-scale atmospheric circulation.

When we jump from the truck and accelerate towards the earth surface, the earth also accelerates towards us but it's acceleration is very negligible.
To find the answer, we need to know about the acceleration of earth due to the gravitational attraction.
<h3>What's the gravitational force between the earth and a person?</h3>
- Gravitational attraction force is GMm/r² between the earth and a person.
- M= mass of the earth
m= mass of the person
r= separation between them.
<h3>What's the acceleration of the earth towards the person when he jumps from a truck?</h3>
- According to Newton's second law, Force = M×acceleration
- Acceleration= Force / M
- Here, Force = GMm/r²,
so acceleration of earth= Gm/r²
- As this acceleration is very small, so we can't notice it.
Thus, we can conclude that the earth also accelerates towards us.
