<h3>What is the Earth system?</h3>
- The interactions between Earth's five systems—the geosphere, biosphere, cryosphere, hydrosphere, and atmosphere—create the conditions we are accustomed to.
- The rock cycle, the food chain, the carbon cycle, the nitrogen cycle, the water cycle, and the energy cycle are a few examples found in the Earth system.
- The major Earth circulation processes that move water, carbon, and nutrients renew essential elements for life and contribute to climate control. The continents, atmosphere, oceans, ice, and life on Earth are dynamic elements that constantly change and interact in a wide variety of ways.
- A system is made up of four independent spheres. A change in one sphere may result in another change because the spheres interact. Fields are plowed by humans (biosphere) using farm equipment made of geosphere materials, while plants are watered by precipitation (hydrosphere) brought by the atmosphere.

Answer:
The angular displacement would be 6 Pi radians or 1080 degrees.
Explanation:
Every individual rotation is 2 Pi (this applies to anything regardless of radius).
Since there are three rotations you are going to multiply 2 Pi by 3.
This will give you 6 Pi which you can convert to equal 1080 degrees (1 Pi = 180 degrees).
Answer:
Emf induced in the coli will be equal to 26 volt
Explanation:
We have given number of turns N = 13
It is given that magnetic flux changes from 2.1 Weber to 2.7 Weber in 0.3 sec
Change in flux 
Change in time dt = 0.3 sec
We have to find the induced emf
Induced emf is equal to 
So emf induced in the coil will be equal to 6 volt
Newton's Third Law of Motion states that for every action there must exist an equal but opposite reaction.
This ultimately implies that, Newton's Third Law of Motion is a law based on action-reaction force pairs.
In this exercise, you're required to identify the action-reaction forces in the attached picture.
Under condition A, a boy is leaning against a wall;
- The force being exerted by the boy on the wall is a force of action.
- The force being exerted by the wall on the boy is a force of reaction.
Under condition B, a boy is jumping off a diving board.
- The force being exerted by the feet of the boy on the diving board is a force of action.
- The force being exerted by the diving board on the feet of the boy is a force of reaction.
Under condition C, a nail is being hammered into the wall.
- The force being exerted by the hammer on the nail is a force of action.
- The force being exerted by the nail on the hammer is a force of reaction.
Under condition D, a man is walking on a ground (floor).
- The force being exerted by the foot of the man on the ground (floor) is a force of action.
- The force being exerted by the ground (floor) on the foot of the man is a force of reaction.
Under condition E, a boy is holding a ball;
- The force being exerted by the hand of the boy on the ball is a force of action.
- The force being exerted by the ball on the hand of the boy is a force of reaction.
