The conservation of momentum P states that the amount of momentum remains constant when there are not external forces.
We don't have external forces, so:
Where:
- mb is the mass of the bowling ball
- mp the mass of the pin
the initial velocities of the bowling ball and the pin.
the final velocities of the bowling ball and the pin.
Solving for v0b:
<h2>R/ The original velocity of the ball was 5.71 m/s.</h2>
Answer:
b. the electromagnetic spectrum
Explanation:
the electromagnetic spectrum contains all the forms of light, including gamma rays, x-rays, ultraviolet radiation, visible light, infrared, radio waves, microwaves, etc
Answer:
frequency = 5.52 * 10² Hz
Explanation:
the equation that relates velocity, frequency and wavelength is:
velocity = frequency * wavelength
We are given that:
velocity = 331 m/sec
wavelength = 0.6 m
Substitute with the givens in the equation to get the frequency as follows:
velocity = frequency * wavelength
331 = frequency * 0.6
frequency = 331 / 0.6
frequency = 5.52 * 10² Hz
Hope this helps :)
