Answer:
375 ms
Explanation:
the frequency of metronome , f = 160 beats per minute
f = 160 /60 beats per sec
f = 2.67 beats /s
the period of a single beat , T = 1/f
T = 1/2.67 s
T = 0.375 s = 375 ms
the period of a single beat is 375 ms
work done =force /area
=500/50
power =work done * time taken
Answer:
If a star is moving toward Earth, its light waves appear to be squeezed together. The decreasing distance between Earth and the star effectively shortens the wavelength of the starlight received by Earth. This shifts the star's spectral lines toward the blue end of the spectrum.
