how does the electric force between two charged particles change if the distance between them is increased by a factor of 3? a.
Anna007 [38]
D. it is decreased by a factor of 9.

Force = kqq ÷ r^2

The distance is squared so if it is increased or decreased by any factor, then it must be squared too. Because the distance is on the bottom of the equation, you divide the force by the increasing or decreasing factor.

Ted lifts a 10N weight at a height of 1.5 m in 1 second. Johnny lifts a 10N weight at a height of 1.5 m in 2 second. Which state
fenix001 [56]

Answer:

he affirmations the correct ones are: A and D

Explanation:

To find out which expressions are correct, let's calculate the work and power done by each person

the expression for work is W = F and

the expression for power is P = W / t

In this case the work is positive because the beast is in the same direction of displacement.

Ted

        W₁ = 10 1.5

        W₁ = 15 J

        P₁ = 15/1

        P₁ = 15 w

Johnny

the job

         W₂ = 10 1.5

         W₂ = 15 J

the potential

          P₂ = 15/2

          P₂ = 7.5 w

therefore we see that the work of both is the same, but Ted developed twice as much power as Johnny

when resisting the affirmations the correct ones are: A and D
