Use the formula. Plug in known values, so you get f = 3000*2 and get 6000N as a result.
The terminology is somewhat arbitrary, however, In this case, you intentionally alter the angle, which then determines the resulting distance. The presumption of the experiment is that distance is DEPENDENT on the angle. The dependent variable will be the how far the rock went. The dependent variable is the variable that you are testing. The first sentence of description indicates that the experiment is to determine launch Θ vs range.The largest range value is to be determined, so the range is plotted on the Y-axis. Angle Θ is plotted on the X-axis. The distance depends on the launch of the angle so the answer will be (D) how far the rock went. It is the dependent variable.
Wait I don't see the question... Can you comment me in it so I can see? I think it's a glitch or something..
Answer:
sound Requires a medium in order to travel.
The force of attraction for the states of matter, which can be ignored for most part of calculation or observation, is the gases.
<u>Explanation:
</u>
Gases have incredibly less force of attraction. The inter molecular space between the gaseous molecules are so vast that the force of attraction between them is negligible.
And, for a matter of assumption for smooth calculation, factors which are negligibly less can be ignored. And, thus, for most part of science, the attractive force is ignored among the gaseous particles.
