Explanation:

Power is the product of current and voltage:

P = IV

And from Ohm's law, voltage is the product of current and resistance:

V = IR

So substituting this expression for V into the power equation:

P = I (IR)

P = I² R

Answer:

P = IV

Ohms law gives voltage as the product of current and resistance i.e.  

V =IR

Replacing this in the previous equation gives

P= I(IR) = I^2R  

Explanation:

applying ohms law V=IR

The force of Earth's gravity pulls down on a stone after someone tosses it off a cliff. What is the "equal and opposite force" d
Lapatulllka [165]

The equal and opposite force is the force of the stone's gravity pulling up on thy Earth.

<u>Explanation</u>:

                                      F_{AB} = - F_{BA}

  • 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.
