The frequency of the radio waves from the fm station is:
And the speed of the waves corresponds to the speed of light:
Therefore, the wavelength of the radio waves can be found by using the following equation:
And the speed of the waves corresponds to the speed of light:
Therefore, the wavelength of the radio waves can be found by using the following equation:
Find the speed with which the disk slides across the surface
Answer:
Explanation:
The Potential energy of spring is transformed to kinetic energy hence
Here k is the spring constant, x is the extension of spring, v is the velocity of disk and m is the mass of the disk.
Substituting 0.117 Kg for m, 194 N/m for k and 0.07 m for x then
