enot [183]

Answer:

Earth, Solar system, Milky way galaxy,Local group, super cluster, Universe.

Explanation:

We usually write our address starting from house no then street no then the town or city and after that comes the province and country. So we write address starting from smaller to larger. Let's do it in this case.First comes the planet earth which lies in the solar system. So our solar system is a smaller part of the milky way galaxy. Milky way galaxy is just a one galaxy in the cluster of galaxies which is called the local group.Local group is further a part of a super cluster. Then comes our universe which consists of 10 million super clusters.

A horizontal force of 300.0 N is used to push a 145-kg mass 30.0 m horizontally in 3.00 s. Calculate the power developed.
Svetradugi [14.3K]

Answer:

3 * 10³J/s

Explanation:

Given :

Force applied, F = 300 N

Distance, d = 30 m

Time, t = 3 seconds

Power, P = Workdone / time

Recall :

Workdone = Force * distance

Workdone = 300 N * 30 m = 9000 Nm

Workdone = 9 * 10³ J

Power = (9 * 10³ J) / 3s

Power = 3 * 10³J/s

If you double the dimensions of a cube what happens to the volume
Triss [41]
By definition, a cube is a three-dimensional figure that have equal dimensions for all its sides. It comprises of two square bases, one on top and one on the bottom. The face sides are also squares. Therefore, the volume of a cube is equal to s³, where s is the measure of the side's length. To compare the change, let us assume values. First, suppose s=1. Then, we denote this volume as V₁.

V₁ = (1)³ = 1

Next, taking the double, s=2. The volume for this is denoted as V₂.

V₂ = (2)³ = 8

Taking the ratio of V₂ to V₁:

V₂/V₁ = 8

That means the scale factor is 8. When the side dimensions is doubled, the volume of the cube increases 8 times as great as the original volume.
