Answer:
you need to provide a figure that came with the problem.
Answer:
D) Einstein proved it is impossible to have a redshift greater than 1; these are all due to gravitational lensing tricking us
Explanation:
By Einstein's theory of relativity the maximum value of the red shift is 1. This correspond to a case in which the observed frequency equals the emitted frequency:
in other cases the red shift is lower than one.
Hence, the gravitational lens change the measurements of the observed frequency and because of that we calculate a greater red shift.
Hence, the answer is:
D) Einstein proved it is impossible to have a redshift greater than 1; these are all due to gravitational lensing tricking us
hope this helps!!
Answer:
7.54 m/s
Explanation:
C = 2πr
C = 2π (0.450 m)
C = 2.827 m
v = d / t
v = 25.0 (2.827 m) / (9.37 s)
v = 7.54 m/s
Answer:
Explanation:
From the question we are told that:
Mass
Potential difference
Magnitude
Generally the equation for Velocity is mathematically given by
Generally the equation for Force is mathematically given by
Where
Therefore
The answer is option C .Because as the direction of the boy changes ;velocity changes .
