Answer:

Redshift means stars and galaxies are emitting a color that is shifting toward the red end of the color spectrum. this indicates the light's wavelengths are <u>MORE</u> and less frequent, and the star or galaxy is <u>MOVING AWAY</u>

Explanation:

As we know that by Doppeler's effect of light when source is moving away from the observer then the frequency observed by the observer is given as

\frac{\Delta \nu}{\nu} = \frac{v}{c}

so here on moving away the frequency observed by observer will decrease and hence we can say that the wavelength of light must be increased

So here on increasing the observed wavelength we say it to be shifted towards higher side which means it is red shift

so here correct answer would be

Redshift means stars and galaxies are emitting a color that is shifting toward the red end of the color spectrum. this indicates the light's wavelengths are <u>MORE</u> and less frequent, and the star or galaxy is <u>MOVING AWAY</u>

If a star collapses to a tenth its size, gravitation at its surface increases by?
tino4ka555 [31]

If a star collapses to a tenth its size, gravitation at its surface increases by 100 times as much.

The contraction of an astronomical object caused by its own gravity, which tends to pull stuff inward toward the center of gravity, is known as gravitational collapse. A cloud of interstellar matter gradually collapses under the influence of gravity to form a star. The temperature rises as a result of the compression brought on by the collapse until thermonuclear fusion takes place in the star's core. At this point, the collapse gradually comes to an end as the outward heat pressure equalizes the gravitational forces. Following that, the star is in a condition of dynamic equilibrium. A star will repeatedly collapse once all of its energy sources have been used up until it reaches a new equilibrium condition.

What is the difference between center of mass and center of gravity?
sweet [91]

Answer:

Centre of mass is the point at which the distribution of mass is equal in all directions, and does not depend on gravitational field. Centre of gravity is the point at which the distribution of weight is equal in all directions, and does depend on gravitational field.
