Which is not standing in the way of astronomers getting a good view of distant stars?

The situation wherein the redshift is making the stars difficult to see is not, in any way, preventing the astronomers from getting a good view of distant stars.

When light or other electromagnetic radiation from an object is expands in wavelength, or moved to the red end of the spectrum, the redshift happens. An increase in wavelength and being equivalent to a lower frequency and a lesser photon energy, following the quantum theories of light and the wave is called the redder, whether or not the radiation is inside the spectrum.

The spectroscopic observations of astronomical objects can see redshifts and its value is regarded by the letter z.

Plain and simple. Redshift makes stars difficult to see. Apex verified and confirmed.

Explanation:

f is prop to m1xm2 double m1 double force

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
