The Hubble telescope’s orbit is 5.6 × 105 meters above Earth’s surface. The telescope has a mass of 1.1 × 104 kilograms. Earth exerts a gravitational force of 9.1 × 104 newtons on the telescope. The magnitude of Earth’s gravitational field strength at this location is

Answers

Answer 1

Answer:
Gravitational force = 9.1 x 10⁴ newtons

Mass = 1.1 x 10⁴ kilograms

Gravitational field strength = 9.1 x 10⁴ newtons / 1.1 x 10⁴ kilograms

= ( 9.1 / 1.1) (newton / kilogram)

= 8.3 newton/kg

or 8.3 m/s² .

What is an example of Deceleration?

Answers

That's a word often used to mean "slowing down". An example is what happens
when the brake is applied in a moving car.

But 'deceleration' is a very unofficial, unscientific word. If the forward speed
is decreasing, then a much more useful concept is "negative acceleration".

When the body starts moving with a slower speed than the initial speed and it slows down continuously, the this is called deceleration. Examples of deceleration -

When a ball is thrown upwards, its speed goes on decreasing as its height increases.
When a car applies brakes.

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.

How did Marie Curie’s research in radioactivity benefit others while harming her

Answers

The discoveries Mme Curie made were of great benefit to physics, chemistry and medicine. During the time she was doing her research, the health effects of ionizing radiation were not known. The amount of radiation that she was exposed to led to her death. Even today her notebooks and other personal effects are highly contaminated with radioactive material.

You need to raise a heavy block by pulling it with a massless rope. You can either (a) pull the block straight up height h, or (b) pull it up a long, frictionless plane inclined at a 15∘ angle until its height has increased by h. Assume you will move the block at constant speed either way.

Answers

Final answer:

In both scenarios, the work done on the heavy block is the same, as it is determined by the change in the vertical height. However, pulling the block up the inclined plane may require less force because the work is distributed over a larger distance.

Explanation:

The subject of this question is based on the concept of work and energy in physics. When you pull the heavy block straight upwards (scenario a), the work done is equal to the force times the distance, or Work = mg*h, where m is the mass of the block, g is the acceleration due to gravity, and h is the height it needs to rise. For pulling the block up the inclined plane (scenario b), the work done still equals mg*h as the vertical distance it rises is the same.

This is because, according to the principle of work and energy, the work done on an object is equal to the change in its kinetic energy. Since the speed of the block remains constant in both scenarios, the kinetic energy does not change, meaning the work done on the block is the same in both scenarios.

However, pulling the block up the inclined plane may require less force because of the larger distance over which the work is done. But the overall work is the same in both cases.
