Answer: The color of a star plays a significant role in determining its age as well as its temperature. A star normally appears to be shining as we see through the atmosphere. An increase in the temperature of a star releases more energy and this can be observed in the various colors of color spectrum.
The hottest star generally appears to be bluish-white in color whereas the coldest star usually appears to be reddish in color.
Thus, a star's color can help us determining its temperature.
For the answer to the question above, it is A. Sea Breeze or <span>on shore, </span>breeze<span> is a gentle wind blowing from the </span>sea<span> toward land, that develops over bodies of water near land due to differences in air pressure created by their different heat capacity. It is a common occurrence along coasts during the morning as solar radiation heats the land more quickly than the water.</span>
Answer:
Explanation: do y like me yes or no
Answer:
a) t = 2 10⁻² s
, t = 2.4 10-1 s
Explanation:
In this exercise they indicate the delay in two signals
a) A signal travels on an electrical cable, between New York and London.
The wave formed in this wire for the signal. This wave travels at the speed of light, c = 3 108 m / s, so the delay is very small
t = d / c
t = 6000 10³/3 10⁸
t = 2 10⁻² s
b) The signal points to a satellite in geostationary orbit
distance traveled = √ (2 36000 10³)² + 6000²
distance = 72 10⁶ m
the waiting time is
t = d / c
t = 72 10⁶/3 10⁸
t = 2.4 10-1 s
we can see that the signal sent by the satellites has more delay because its distance is much greater
