Air pressure changes with altitude because of issues related to gravity. Molecules have more weight the closer they are to the Earth and more of them move to lower elevations as a result; this causes increased pressure because there are more molecules in number and proximity. Conversely, air at higher elevations has less weight, but also forces pressure on those layers below it, resulting in the molecules closer to the Earth supporting more weight, increasing the pressure
Answer:
true

depends on how young it starts usually at age 10 or 12 sometimes 13 are the most common ages to start this
Answer:
Because each color is refracted differently, each bends at a different angle, resulting in a fanning out and separation of white light into the colors of the spectrum.
Answer:
Explanation:
Unbalanced Force according to newton's second law is the one which causes the object to move or break its state of rest on application of force.
Here the object accelerate to a speed of 4 m/s and moves a distance of 5 m on application of force .
Thus we can say that the applied force is unbalanced in nature.
