The equal and opposite force is the force of the stone's gravity pulling up on thy Earth.
<u>Explanation</u>:

- When someone tosses a stone off a cliff, the force of gravity of Earth pulls down and the force of the stone's gravity pulls up on the Earth due to the equal and opposite reaction exerted between the Earth and the stone.
- In Newton's third law, two important features are present. One is the force exerted on two bodies will have the same magnitude but opposite direction. The other feature is force is acting on two different objects.
- This exerted force is equal in magnitude but opposite in direction whereas the gravity exerts a downward force on a stone and upward force on an Earth which is opposite in direction.
Considering the answers.
1. Halve the voltage across it
2. Quarter the voltage across it
3. Double the voltage across it
4. Quadruple the voltage across
The appropriate answer would be 3. Double the voltage. According to ohms law the current through a conductor between two points is directly proportional to the voltage across the two points at a constant resistance. Therefore a increase in voltage causes a corresponding increase in the current.
Answer:
true
Explanation:
when a ray of light travels from a less denser medium to a denser medium it tends to bend towards the normal.
2.5 joules according to the formula k=1/2MVsquare we would get 2.5 joules as the answer
The option that defines the opposition to the flow of electrical current is D. resistance.
