Answer:
C
Explanation:
When the frequency of sound changes, we hear a change in pitch. When the frequency of light changes we see a change in color.
Momentum is mass times velocity of the object
p = m • v
p = (7700 kg)(14 m/s)
p = 107809 kg m/s
Answer: 0.14 Hz
Explanation:
We are told the person counts 10 waves in 68 s, from this information we can calculate the frequency , which is defined as the number of oscilations or waves per unit of time. Then:
This is the frequency of the ocean waves. Now, according to the International System of Units (SI), frequency is measured in Hertz (), which is equivalent to .
So, according to this, the frequency of the ocean waves is
Energy is carried to Earth in a form of photons or simple radiation.
