Answer:
150J
Explanation:
work output/work input=100%
so just make work output the subject
We are given an electromagnetic wave with a frequency of 5.09 x 10^14 Hz and travelling through a transparent medium. If the medium was vacuum, the speed of the wave would be equal to the speed of light. Otherwise, the main factor that would determine the speed of the wave is its wavelength.
When you are going down you pick up more speed
I think is A or B it depends on like what the trying to answer
Answer:
Average speed equals distance / time
380 / 40 = 9.5 m/s.
