What is intertia? Explain.

Answers

Answer 1

Answer:

Answer:

Law of inertia, also called Newton's first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

Hopethisanswerisright!

Answer 2

Answer:

Answer:

property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.

Grass obtains 10% of the energy of the Sun. When a mouse eats the grass, it gets only _____ of the Sun's energy while _____ is lost as heat. 0.1%; 0.9% 1%; 0.9% 0.01%; 0.009%

Answers

Grass obtains 10% of the energy of the Sun. When a mouse eats the grass, it gets only 1% of the Sun's energy while 9% is lost as heat. It has already been known that only 10% of energy gets transferred from one link of the food chain to another. The answer to this question can be easily deduced from this fact.

APEX What is one advantage of using primary sources when doing research on anexperiment?
A. They are summaries of many scientists' work.
B. They include the opinions of many scientists.
C. They contain more details about the experiment.
D.They are always easier to read.

Answers

One advantage of using primary sources when doing research on an

experiment is they contain more details about the experiment. The correct option is C.

What are primary sources?

Primary sources are the one which are first hand sources. They are more reliable, so they are more reliable and detailed about the experiment.

Primary sources are the sources which produce their own energy to let other objects emit the same. Just like, Sun, it has has its own light and heat energy. It is reliable and can be experimented with more details.

Thus, the correct option is C.

Aristotle supported which of these views? The Sun and all the planets revolve around Earth. The speed of a free-falling object is independent of its weight. Earth and other planets revolve around the Sun. Every action has an equal and opposite reaction. The fifth element, ether, does not exist in heavenly bodies. NextReset

Answers

Final answer:

Aristotle supported geocentrism, the view that the Sun and all the planets revolve around the Earth. He did not support the concept of free-fall speed being independent of weight, a concept later verified by Galileo. Aristotle also proposed the existence of a fifth element, ether, in heavenly bodies.

Explanation:

Aristotle, the ancient Greek philosopher, supported the view that the Sun and all the planets revolve around the Earth. This model is known as Geocentrism or Ptolemaic system. His belief was widely accepted until the Copernican revolution in the 16th century, which provided a heliocentric model. The heliocentric model, the belief that the Earth and other planets revolve around the Sun, was questioned by Aristotle.

Furthermore, Aristotle did not support the view that the speed of a free-falling object is independent of its weight. This idea was later verified by Galileo. Also, the idea of every action having an equal and opposite reaction is associated with Newton's third law of motion, a concept that emerged much later than Aristotle's time. Lastly, Aristotle did propose the existence of a fifth element, ether, that he believed existed in the heavenly bodies. Hence, he did not support the view that ether does not exist in heavenly bodies.

Aristotle believed the earth was the centre of the solar system, with the sun, moon and planets 'orbiting' it on 'celestial spheres'.

In fact the idea Aristotle had was that this explained something about the nature of the universe. He noticed that when you push an object, it slows down and stops. Therefore he divided the universe into 'earth-like stuff' which preferred to remain stationary, and 'heavenly stuff' which preferred to be in motion. Newton showed this idea to be false when he effectively unified motion and being at rest - if you move at a constant velocity (like in a very large ship) you can't tell if you're moving at a constant velocity or whether you are at rest

When the temperature of an object increases, what happens to the kinetic energy of the particles in the object? A.It is conserved.

B.It equals zero.

C.It increases.

D.It decreases.

Answers

When the average kinetic energy of the particles in the object increases, we sense and measure that change as an increase in the object's temperature.
