Eh? i don’t understand huhu
Answer:
We say that the object's spectrum is shifted.
Explanation:
Spectral lines will be shifted to the blue part of the spectrum1 if the source of the observed light is moving toward the observer, or to the red part of the spectrum when is moving away from the observer (that is known as the Doppler effect).
That shift can be used to find the velocity of the object by means of the Doppler velocity.
(1)
Where is the wavelength shift, is the wavelength at rest, v is the velocity of the source and c is the speed of light.
Answer:
29.6 kg
Explanation:
Centripetal force = mass × centripetal acceleration
F = m v² / r
88.0 N = m (2.50 m/s)² / 2.10 m
m = 29.6 kg
Electromagnet would have a stronger pull than a regular magnet

The most appropriate answers are ...
high frequency sound has shorter wavelength !
a higher pitch than low frequency...!!
so , wavelength and pitch !!
