O rotation of the Moon on its axis
O revolution of the Moon around Earth
O revolution of the planets around the Sun
Answer:
revolution of the planets around the Sun.
Explanation:
The revolution of the planets around the Sun is a result of the gravitational force exerted by the Sun. The Sun's gravitational pull attracts the planets, causing them to move in an elliptical orbit around it. This motion is known as the revolution of the planets around the Sun. The other options listed (rotation of the planets on their axes, rotation of the Moon on its axis, and revolution of the Moon around Earth) are also related to motion and gravity, but they are different phenomena.
The force applied to pull an object is 200 N and the distance it sleds through the snow is 500 meters, so the amount of work done over here is 1,00,000 Nm.
When an external force moves an object over a distance, at least a fraction of that force must be exerted in the displacement's direction. This is known as work in physics. By multiplying the length of the path by the component of the force acting along the path, work can be calculated if the force is constant. The work W is equal to the force f times the distance d, or W = f.d, to mathematically describe this idea.
According to the question, the given values are :
Distance, d = 500 meters
Force, f = 200 Newton
So the formula for work done= force× displacement
W = 200 × 500
W = 1,00,000 Nm
Hence, the work done over here is 1,00,000 Nm.

It is a true fact that the loss of an organism at the bottom of a food chain negatively impacts all organisms in the chain.
Explanation:
This is because if the below organism which is constantly interchanged with plants, no herbivores would eat those plants, thus, will also die, which will also determine that the next consumers will have trifle to eat which will also happen to their deaths. So, yes. It concerns it negatively. And very negatively.
a. True
b. False
