The diagrams below each show the motion of a distant star relative to Earth (not to scale). The red arrows indicate the speed and direction of the star’s motion: Longer arrows mean faster speed. Rank the stars based on the Doppler shift that we would detect on Earth, from largest blueshift, through no shift, to largest redshift. Note:a picture in resemble to solar system is shown in the figure

The ranking of the stars are 5 → 2 → 4 → 3 → 1

Explanation:

To solve the question, we note that an approaching star has a blue-shift, a regressing star has a red-shift and a crossing star will have no shift.

The magnitude of the blue-shift or red-shift is dependent on the speed of the stars.

Therefore we have the rank of the stars based on the Doppler shift that would be detected on earth from largest blue-shift to largest red-shift given as

5 → 2 → 4 → 3 → 1.

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
