Which has more kinetic energy, a feather floating through the air or a rock on the ground? Explain.

Answers

Answer 1

Answer: Well, it would be the feather floating through the air, as the feather is moving and because of it it possess kinetic energy because of its motion. A rock on the ground has no kinetic energy as it is not moving.

Answer 2

Answer:

Final answer:

The rock on the ground has more kinetic energy compared to the feather floating through the air, due to the force of gravity.

Explanation:

Kinetic energy is the energy of motion, and a moving object has kinetic energy. Potential energy, on the other hand, comes in several forms, such as gravitational potential energy. When comparing a feather floating through the air and a rock on the ground, we can say that the rock has more kinetic energy.

This is because the rock, when dropped, falls to the ground due to the force of gravity, gaining kinetic energy in the process. The feather, on the other hand, is floating through the air and not experiencing the same gravitational pull, thus having less kinetic energy than the rock.

What circuit that has only one path for the
current to follow?

Answers

Answer:

Series circuit

Explanation:

By definition series circuit is a closed circuit in which the flow of electric current follows only one path.

In a simple electrical circuit (which is a series circuit) where electric cell is the source of power, each component is connected in such a way that there is only one pathway current flows from the positive terminal(+) round to the negative terminal(-) via the external circuit.

Current having only one pathway to flow means that when one of the components is removed, there will be no current flow.

B.crust, mantle, outer core, inner core
C.inner core, outer core, mantle, crust
D.mantle, crust, inner core, outer core

Answers

The answer is C, Inner core, outer core, mantle, crust.

Well,

Logically, the deeper we go, the hotter it will get.

It turns out that the innermost part of the lithosphere is the hottest, while the outermost part of the lithosphere is the hottest (suprise!).

Option C is correct.
