<u>Answer:</u>

The dependent variable is what changes because of the independent variable in an experiment. The independent variable is what the experimenter changes for different experiment groups, and the dependent variable is the outcome of those changes.

Why doesn’t the sun blow itself up?

statuscvo [17]

An explosion occurs when the timescale for the energy release by some process is much shorter than the timescale on which a system can adjust to damp the energy release process. In the present day Sun, nuclear fusion is a very slow process: on average it takes many billion years for a proton to fuse with another. This timescale is quite temperature dependent, so you might have thought the centre of the Sun might heat up quickly, leading to a runaway "explosion". However, an increase in temperature leads to an increase in pressure that would expand the Sun, reducing the core density and temperature and decreasing the rate of nuclear fusion again. The timescale for the Sun to react in this way is just millions of years, so this acts like a thermostat that keeps the reactions under control.

A company will pay workers at a level that maximizes the company

Lyrx [107]

The correct answer is profits.

That's why if the company sees that a worker's payment is not profitable for the company they either fire the person or lowers their payment. The company always wants to pay taxes as little as possible and reduce the costs. It is not maximizing the costs if it gives high wages.

Answer:

Geography brings a person understanding of why civilizations develop into the societies they are today due to adaptations to the climate, resources, and interactions with other people nearby. Geography shows why regions in the world suffer from the problems more than others and how all civilizations interact with each other in different ways.

A satellite orbiting earth has a tangential velocity of 5000 m/s. earth’s mass is kg and its radius is m. which is the distance

inessss [21]

The distance of the satellite form the earth is:
9,608,000 m (Option C) in Standard form, this is written as 9.6 x 10 $^{6}$ .

<h3>What is an Orbiting Satellite?</h3>

An Orbiting Satellite is a satellite that goes around the earth in an elliptical path known as an orbit.

To calculate the distance of the satellite from the earth we must equalize the force of Gravity to Centripetal Force given that these are the two forces that are at play here.

Step 1:

Equation that equalizes Gravity to Centripetality is:

G = mM/r² = m(v²/r)

Note that G = 6.67 x 10 $^{-11}$ (This is a gravitational constant.)

m is the Mass of the Satellite

M is Mass of the Earth

r is the distance of the satellite from the center of the earth

v is the satellites tangential velocity

Step 2 - Rearrange the formula and substitute the numbers above to get r

r = G (m/v²) = (6.67 x 10 $^{-11}$ ) (6 x10 $^{24}$ /5000²) =

= 1.6 x 10 $^{7}$ m

Recall that form our postulation above, this is the satellites distance form the center of the earth.

To get it's distance form the earth's surface, we must know remove the value of the radius of the earth from the calculation. Where radius of the earth is given a r'

Hence,

r' = r - R = 1.6 x 10 $^{7}$ m - 6.4 x 10 $^{6}$ m

= 9.6 x $10^{6}$ m or 9,608,000 m
