Unlike the one-way flow of energy, matter is recycled within and between ecosystems. Every living organism needs nutrients to build tissues and carry out essential life functions.
<span>The answer is heterogeneous mixture. A heterogeneous mixture is a combination of substances that are combined physically but not chemically. This is a mixture that is not uniform in composition. Its components can easily be separated from one another. For example, pile of soil is a heterogeneous mixture because it consists of different components.</span>
From Simple Harmonic Motion (SHM), the restoring force is given by:
F = -ω²x
We can see that restoring force is proportional to the displacement, x. So if the displacement x is doubled, then the restoring force will also be doubled.
A. Since it does not say the ball is moving your answer is A.
Mechanical advantage is a force which is measure of a force amplifying effectiveness of a simple machine.so t<span>he number of times a machine multiplies the effort force is mechanical advantage .
hope this helps</span>
