The strength of a force is usually expressed by its magnitude. We have also to specify the direction in which a force acts.
Microwaves are one of the lowest energies on the electromagnetic spectrum. While X-Rays are one of the highest energies on the electromagnetic spectrum. One similarity is that they are both on the electromagnetic spectrum. Also they both travel at the spped of light in a vacuum. One way they are different is They have different frequencies and wavelengths. Also they are used for different studies.
It’s important for a scientist to be open-minded because they need to be able to understand or creative anything that was never thought about. It’s also important for a scientist to be skeptical because some ideas or products that they hear about can have false factors. I hope this helped!
We use the following formula to determine our acceleration:

We normally use letters in this formula, which gives us:

Filling in this formula gives us:
Δv (change of velocity) = 12 - 4 = 8 m/s
t = 1s

So our answer: the acceleration is
