Answer:
∘F=(9/5)∘C+32).
Explanation:
Coach Ferguson uses a thermometer to measure the temperature (in degrees Celsius) at 20 different locations in the school swimming pool. An analysis of the data yields a mean of
25∘C
and a standard deviation of
2∘C.
Find the mean and standard deviation of the temperature readings in degrees Fahrenheit (recall that
∘F=(9/5)∘C+32).
<span>The air that is found in soil is extremely different from the air that is found in the atmosphere. Why, you ask? Well, it's because the air that are in soils are not exactly exposed to moving air currents, thus the air that is found in soils are more moist and humid.
Good luck with your studies, I hope this helps~!</span>
frequency's unit is Hz which mean cycles per second
given frequency * wavelength = speed of wave
speed of light = 3x10^8 m/s
wavelength = 680nm = 680x10^-9 m
frequency * 680x10^-9 m = 3x10^8 m/s
frequency = 3x10^8 / 680x10^-9
= 4.41x10^14 Hz
= 441x10^12 Hz
= 441 THz
which is the frequency for red light
