Answer:
3.2m
Explanation:
Given parameters:
Frequency of the FM radio = 9.23 x 10⁷Hz
Velocity of the waves = 3 x 10⁸m/s
Unknown:
Wavelength of the wave = ?
Solution:
To solve for the wavelength of the wave, we need the velocity equation;
Velocity = frequency x wavelength.
Radio waves are all electromagnetic radiations produced by both electrical and magnetic fields perpendicularly oriented to one another.
Since the unknown is wavelength, we solve for it:
3 x 10⁸ = 9.23 x 10⁷ x wavelength
wavelength =
wavelength = 3.2m
It is a question that leads us to know the proportion of one element to another. We have initially that the mass of the earth is of
m_E = 5.98*10^{24}kg
While the mass of the Moon is of
m_M = 7.35*10^{22}kg
The ratio between the two is given by the function
This means that the mass of the earth is 81.36 times larger than that of the Moon.
