<span>(3) one-half as great</span>;
Consider the relationship:
with your data you get:
approx <span>one-half</span> of <u />
Yes. Your weight is pulling you to center of the world. Weight is a force (gravity).
And since you're still on where you sit, the thing you're sitting on, exerts an equal force to your weight. That's stated in Isaac Newton's third law of motion. Simply 'For every action, there is an equal and opposite reaction.'
Answer:
I. Models are always wrong unless they are proved by a theory. TRUE
II. Elements, such as lead, are made of tiny particles that mostly consist of open space. FALSE
III. The air you breathe is an example of a heterogeneous mixture. FALSE
IV. An isotope of silver-108 has 61 neutrons. TRUE
Explanation:
I. All models are wrong because in order for them to be applied to reality, certain aspects that do not fit the theory must be considered.
II. All elements are made by atoms.
III. The air is an example of a homogeneous mixture of different gases. IA homogeneous system is that material system that has the same intensive properties in any part of that system. One way to check it is by viewing it. If the different parts that make it up cannot be distinguished, it will be homogeneous.
IV. Atomic number of Silver is 47. So if its mass number is 108, it has 61 neutrons and 47 protons
Answer: false
Explanation:
Hi, The Michelson-Morley experiment was designed to measure the extra time it took a light beam to travel "there-and-back" against the ether wind, compared to a light beam travelling "sideways across" the ether wind.
The experiment failed, there was no variation, and years later Einstein explained that there is no ether. Light is a special sort of wave which requires no medium to carry it.
