Answer:
Explanation:
The main cause of different parts of the earth receiving different amounts of solar energy is as a result of the tilt of the Earth. Having different latitudes also play a role in that, as latitudes are used to measure the distances between places on earth(together with longitude) receiving different amounts of solar energy also leads to having different atmospheric circulation. Making some places have more heat, while other places have lesser heat energies. Logically, the areas with higher presence of solar energy are going to be hotter than places with lesser presence of solar energy.
Whenever there is a change in velocity, either due to a change in speed or a change in direction, there will be non-zero acceleration. ... Acceleration is not constant if the net force is not constant.

Answer:
Explanation:
A)
vf² = vi² + 2(a)(d)
(54 m/s)² = (27 m/s)² + 2(a)(120 m)
a = 9.1125 m/s²
a = 9.1 m/s²
B)
d = (vi)(t) + (1/2)(a)(t²)
150 m = 0 + (1/2)(9.1125)(t²)
t = 5.7 s
C)
vf = vi + (a)(t)
27 m/s = 0 + (9.1125)(t)
t = 3.0 s
D)
d = (vi)(t) + (1/2)(a)(t²)
d = 0 + (1/2)(9.1125)(2.96²)
d = 40 m
When two waves interact with their crests and troughs in alignment is called constructive interference. If two waves of the same wavelength occupy the same space in such a way that their crests and troughs align, the wave they produce will have an amplitude greater than that possessed by either wave initially. This is known as constructive interference. The more closely the waves are in phase—that is, perfectly aligned—the more constructive the interference.
