Answer:
The wavelength of wave is 2.78 m.
Explanation:
Frequency of a wave is 90 Hz
Speed of a wave is 250 m/s
It is assume to find the wavelength of wave. The formula of speed is given by :
So, the wavelength of wave is 2.78 m.

Answer:
T=270 K
Explanation:
Power absorbed by the Moon
the reason for choosing the area as π R^2 and not 4π R^2 is because the absorbed light is only from the surface facing the Sun which is a disc.
Using Stefan Boltzmann's law,
So, using Conservation of Energy,
this gives, T = 270 K. This is the temperature of the sunlight side of the Moon.
The sun exerts the strongest g-force, holding us (earth)in it's orbit, followed by the moon which affects the tides on earth.
The sun exhibits multiple temperatures from the core to the corona, with a range of over 25 million degrees Fahrenheit.
"Decimeter" is a unit of length or distance, whereas "milliliter" is
a unit of volume. They measure different quantities, and have
different physical dimensions. Neither one can be converted to
the other one.
If it were possible to convert volume to length or distance, you
(or someone with a better handle on his math and physics) could
figure out how many inches of milk you poured on your cereal.
