D. All of the above
PLZ MARK ME AS BRAINLEIST ;)
Answer:
T=13.72N
Explanation:
The tension before the ball is released have no angle is in rest at the same axis of the weight so:
∑F=0
Using Newton law in this case the ball is tied so tension before become to swing is
∑F=FN-T=0
This is a concave mirror you're talking about, so all of the points are going to converge to a single focal point. Therefore the answer would be that it bounces back toward a single spot
<span>Answer : P = 3527 Pa
Explanation:
Given : height, h = 279 m
and density of air , Ď = 1.29 kg/m3
Change in pressure , P = h*Ď*g
We know that gravity, g = 9.8 m/s2
Therefore P = 279 * 1.29 * 9.8 = 3527 Pa</span>
The average daily annual temperature range is exceeded in places such as deserts. Deserts tend to be hotter due to the lack of water contained within them. This means that all of the sun's thermal radiation heats up the ground and air. These factors cause deserts to have above average temperatures.
