The least common shape for a galaxy is irregular elliptical cluster spiral spherical

Question: The least common shape for a galaxy .

Cluster

 cluster

Explanation:

There are four main shapes of galaxies: spiral, galaxies are divided into four main groups: spiral, lenticular, elliptical, and irregular, elliptical, and irregular.

The least common shape is cluster

Spiral galaxies- These are the most common. These have arms extending from a bright bulge in spiral shape.

Elliptical galaxy have ellipsoidal shape.

Lenticular galaxies - Intermediate between elliptical and spiral galaxies.

Irregular shape- No well defined shape

Spherical - Nearly spherical galaxies. These are least

cluster- group of galaxies having irregular shape is the least common shape.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
