Why is less force needed to keep an object moving than to start the object in motion?

1 answer:

5 0

An object in motion needs less force to continue moving because the inertia or the resistance to change in motion was already overcome and the sliding friction that opposes a moving object is also lesser. Therefore, it is easier to move an object at constant velocity as you only need to overcome the resisting forces of the object.

vekshin1

Explanation:

When using chromatography, the 2 solutes in the solvent paper should have different Rf values from the base line to identify them as different compounds.

If they were to have the same speed in the solvent, they would appear as 1 dot instead of 2 separate dots, which is a false reading.

In your own words define what "Social Darwinism" is. How did this theory allow or promote imperialism?

Yuliya22 [10]

"Social Darwinism is a modern name given to various theories of society that emerged in the United Kingdom, the United States, and Western Europe in the 1870's, and which are claimed to have applied biological concepts of natural selection and survival of the fittest to sociology and politics", so, in therory, it would allow AND promote imperialisim, as many people are not within the same level of society.

Find the mean, median, and mode of the following list of values. Round to the nearest tenth if necessary.

grin007 [14]

Answer:

D.

Mean: 24.8

Median: 26

Mode: 26

Explanation:

The mean is the average. To find the average, add up all the numbers and divide by the amount of numbers there are.

30 + 26 + 25 + 11 + 34 + 20 + 26 + 26 = 198

Now, we divide by how many numbers we started out with (8).

198 divided by 8 = 24.75, rounded would be 24.8

To find the median, you arrange the numbers from smallest to largest, and find the middle number like this:

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the middle number is 26.

To find the mode, you arrange the number from smallest to largest, and find the number that appears more often.

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the number 26 appears the most often.

So, we end up with:

Mean: 24.8

Median: 26

Mode: 26
