Answer:
b. K = U
Explanation:
In this case you have that there are no non-conservative forces over the pendulum. Hence, the total mechanical energy if the pendulum must conserve. You take into account that the potential and kinetic energy of a pendulum are given by:

m: mass of the pendulum
h: height of the pendulum
v: speed
In each moment of the trajectory of the pendulum ET does not change.
You have that, at the lowest point U=0J and for the highest point K=0J. For that point K=ET and U=ET respectively.
Hence, for a mid-way between those points it is necessary that:
b. K = U
Answer
a force between two bodies, molecules, particles, or the like, that attracts each to the other. Gravity is the force of attraction between two bodies that have mass.

Answer:
Scandium with an ion charge of +3
Explanation:
Heat is always transferred through the movement of matter in the convection mode of heat transmission.
<h3>What is heat transfer ?</h3>
Heat transfer is the movement of heat from one solid or liquid item to another. Always, heat moves from one body with a greater temperature to one with a lower temperature. To put it another way, heat always transfers from a hotter body to a cooler body.
- Heat energy is transferred through the mechanism of conduction when nearby atoms or molecules collide. In solids and liquids, where particles are more closely spaced, conduction happens more easily than in gases, where particles are more widely spaced.
- Here we can say that heat is transfer when there is movement between two books and hence there is change in temperature.
