Answer:
convergent evolution is the correct answer.
Explanation:
From the computation, the magnitude of the drag force when the skydiver reached terminal speed is 784 Newtons.
<h3>How to calculate the magnitude</h3>
From the complete information, the skydiver has a mass of 80kg and jumps off a plane. The free-fall acceleration is also given as 9.80m/s².
Therefore, the weight of the skydiver will be:
W = mass × acceleration
W = 80 × 9.80
W = 784N
In conclusion, the magnitude of the drag force due to air resistance is 784N.

Explanation:
this question is more of what do bears actually do
The conversions are:
Electrical to electromagnetic and mechanical (when we turn on the microwave).
Electromagnetic to thermal (as the microwave heats up the cup of water).
<h3>
What energy conversions occur?</h3>
We will describe the process in which you already have a cup of water inside the microwave.
First, you turn on the microwave. Here you are giving the microwave electrical energy so it can work.
The microwave rotates the cup of water, so there is a transformation of electric energy into mechanical energy.
The microwave also creates electromagnetic radiation which affects the cup, so there is a change from electric energy to electromagnetic energy.
This electromagnetic energy interacts with the water by increasing the temperature, so finally we have a change from electromagnetic energy to thermal energy.
