How do scientists determine motion of objects in the universe? ?

By Doppler effect

Explanation:

The spectrum of the objects in the universe such as stars and galaxies is taken and studied. The apparent change in the frequency/wavelength of the light suggests the motion of these objects.

If the apparent frequency is greater, the light would be blue -shifted which means it is moving towards Earth and if it is red shifted, it would be moving away from the earth. This is apparent change in observed frequency is known as Doppler's effect which studied to determine the motion of objects in the universe.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
