Testable: Able to be tested or tried.

<em>ex. An example of a testable hypothesis is, Students who attend class more have higher grades, while those who skip have lower grades. </em>

Data: Data is the items of information that represent our analyze, or our findings in an experiment.

<em>ex. An example of Data, is the results of information collected for a research paper.</em>

Evidence: Evidence is information that helps show whether a proposed idea is valid.

<em>ex. We can use evidence to help support our point and strengthen our findings with reasoning.</em>

Theory: Theory is an explanation of something in the natural world that can be tested and gives us the same results each time. A proven hypothesis.

<em>ex. Examples of scientific theories are gravitation, evolution, and plate tectonics. </em>

Hypothesis: A hypothesis is a theory or question that can be tested through study and experimentation. It has more reasoning to it than a simple guess, but not enough information to be a theory.

<em>ex. An example of a possible hypothesis is, If we play music while working on homework, the participant's perfomance will increase.</em>

What would increase the force of gravity between two objects?
yulyashka [42]
By Newton's Law of Universal Gravitation.

F =  GMm/r²

Where F is Force of Gravitation, M = Mass of first object, m = mass of second object, r = distance of separation

From the formula, you can see that if the masses, M and m, increased, the value of F would definitely increase as well.

And if r increased the value of F would be reduced because you would be dividing by a bigger number, but when the value of r is decreased the value of F would be increased, because you would then be dividing by something smaller. Note the r is at the denominator of the formula.

So F would increase if there was increase in Masses and decrease in distance.

So the answer is C. a and b.

Travels most slowly through a gas

Speeds up when temperature is increased

Is caused by vibration

Explanation for correct answers:

Yes, it does travel in longitudinal waves

Yes, sounds weird, but travels faster in the water

Yes, does speed up when temperature is increased

And yes, Is caused by vibration.

<h2>Wrong answer is:</h2>

Can travel through a vacuum

Explanation for wrong answer:

actually, in space, there is NO sound, because there are no particals for the sound to vibrate with, there's just empty SPACE.

What came first the chicken or the egg.
JulsSmile [24]

Answer:

Explanation:

Eggs, generally speaking, existed before chickens did. The oldest fossils of dinosaur eggs and embryos are about 190 million years old. Archaeopteryx fossils, which are the oldest generally accepted as birds, are around 150 million years old, which means that birds in general came after eggs in general.

Hope this helped and have a good day
