Answer:
Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes.
It might be pull at a force of 100 N. I might be wrong.
A
The delta indicates a difference or change. such as delta y is the change in y position
If the object's velocity and acceleration have <em>opposite signs</em>, then the object is slowing down.
The infrared<span> (</span>IR<span>) and the </span>ultraviolet(UV<span>) represent the two extremities of the visible spectrum (400-700nm). While </span>IR<span> represents electromagnetic radiation
with wavelengths longer than those of visible </span>light<span>, </span>UV<span> represents wavelengths
shorter than visible </span>light<span>.
