Answer:
A) a force of repulsion, because they are like-charged.
Explanation:
when the charged sphere is made in contact with the uncharged sphere some of the charges from will flow from the charged sphere to an uncharged sphere thus both become like charged therefore they repel each other.
Answer: Noise pollution also impacts the health and well-being of wildlife. Studies have shown that loud noises cause caterpillars hearts to beat faster and bluebirds to have fewer chicks.

Answer:
The spring constant of the spring is 180 N/m.
Explanation:
It is given that,
Mass of the block, m = 0.42 kg
The block is pulled so that the spring stretches for 2.1 cm relative to its unstained length.
When the block is released, it moves with an acceleration of . We need to find the spring constant of the spring. For a block to be in equilibrium, the net force is given by :
k is spring constant of the spring
So, the spring constant of the spring is 180 N/m.
<span>All of these are directly proportional to each other, meaning that if one goes up or down, they all do the same.
So if the temperature increases so does the heat. If the heat increases then so does the thermal energy. If the temperature goes up then so does the thermal energy. ETC...</span>
