NEED ASAP PLEASE !!! Suppose that a block is pulled 16 meters across a floor. What amount of work is done if the force used to drag the block is 22 N?

A. 200 J
B. 330 J
C. 352 J
D. 220 J

Answers

Answer 1
Answer:

Answer: Option (C) is the correct answer.

Explanation:

Work is defined as the energy required when force is applied in a certain direction.

The expression for work, force and distance is as follows.

                        W = F × d

where,      W = work

                 F = force

                 d = distance

It is given that force applied to drag the box is 22 N and distance is 16 meters. Therefore, calculate work done as follows.

                        W = F × d

                            = 22 N × 16 meters

                            = 352 Nm               (1 Newton meter = 1 joule)

or,                   W = 352 J

Thus, we can conclude that amount of work done is 352 J.
Answer 2
Answer: work = force x distance
22N x 16m = 352 J

Why are the very first stars thought to have been much more massive than the sun? (a the clouds that made them were much more massive than todays star-forming clouds. (b the temperatures of the clouds that made them were higher because the clouds consisted entirely of hydrogen and helium. (c star-forming clouds were much denser early in time?

Answers

I think the correct answer would be that the temperature of the clouds that made the very first stars where thought to be higher since the clouds are made up of hydrogen and helium. Hope this answers the question. Have a nice day.
The main reason why the very first stars where thought to be much bigger than the sun because of the temperature of the clouds that these stars were made of were higher. The clouds that mostly form these stars consist of entirely hydrogen and helium. The answer for this would be option B.

After France fell to the Axis powers in 1940, what percentage of the country was placed under German control?A. 25 percent
B. 50 percent
C. 60 percent
D. 100 percent

Answers

Correct answer choice is:

B. 50 percent

Explanation:

France Capitulates to Nazi Germany. On June 22, 1940, the French state approved a cease-fire with Nazi Germany just six weeks after the Nazis began their incursion of Western Europe.

Paris began preparing for combat in September 1939, when Nazi Germany overran Poland, but the combat appeared far beyond until May 10, 1940, when the Germans invaded France and immediately took the French troops. The French administration left Paris on June 10, and the Germans controlled the capital on June 14.
25 % of the population was in controlled by Germany after France fell to the Axis power. Germany ruled over France and made things that caused the French people to create a revolution. This was one of the greatest revolution so far in the history where the French people united just to get their freedom back.

Magnetism is aA) force.

B) power.

C) form of energy.

D) form of electricity.

Answers

Answer: The correct answer is "force".

Explanation:

Magnet has two poles: South pole and North pole.

Magnetic field lines are the surrounding around the magnet in which magnetic force can be experienced.

Like poles repel each other. There is force of repulsion between like poles. Unlike poles attract each other. There is force of attraction between the opposite poles.

Magnetism is a force. It is not a power. The power is the rate of doing work.

Magnetism is not a form energy.

Therefore, the correct option is (A).
your answer would be a, it is a  force.
