At the top of the arc in a swinging pendulum the value of the kinetic energy is zero.
<h3>
What is Kinetic energy?</h3>
This is defined as the energy possessed by a body virtue of its motion or movement.
When a pendulum swings, it possesses kinetic energy which is usually zero at the top of the arc after which it possesses potential energy as a result of the resting position.

Answer:
4A
Explanation:
Current is charge per time. So if the second wire delivers twice as much charge in the same amount of time, it must have twice the current.
2 × 2A = 4A
Arrhenius' equation relates the dependence of rate constant of a chemical reaction to the temperature. The equation below is the Arrhenius equation
where k is the rate constant, T is the absolute temperature. As the temperature of the system increases, the rate constant also increases and vice versa.
Gamma radiation. Alpha and beta can be stopped relatively easily
