Answer:
Explanation:
Velocity of a wave is describe as
velocity =Frequency × Wavelength
Mathematically
v = fλ
Hence, Frequency, F = v / λ
Wavelength λ = v/f
So, if the frequency is kept constant, wavelength of the wave becomes directly proportional to velocity of the wave.
And this implies that, as the speed double, the wavelength is double.
Explanation :
Edwin Hubble used a telescope to discover the movement of galaxies in 1929. He was an American Astronomer.
The telescope invented by him is called a Hubble telescope. It has a 2.4-meter mirror.
He gives the relation between the distance to a galaxy and its recessional velocity. This is known as the Hubble law. The relation is as follows :
where,
is recessional velocity.
is Hubble constant.
is distance.
<em>So, the given statement is True.</em>
-4.4 ft/s^2
Explanation:
Final Velocity= 35 mph
Starting Velocity= 50 mph
Elapsed Time= 5 seconds
When plugged into formula for Acceleration it is this
