Answer:
Now you know gravity is a major force in the universe. It keeps us from floating away, controls the ocean's tides, guides plant growth, keeps Earth and other planets in orbit.

Answer:
I did this essay before, its not hard. Just read through it carefully and you'll figure it out. or just ask you mom, dad, guardian, or teacher for help
Answer:
In a closed-loop system, matter is used to generate energy, and the energy generated is used to produce matter, and the cycle goes on without end.
Explanation:
A closed-loop system is one in which materials or energy is recycled without end through a production cycle. This means that a raw material is used to produce a finished product, and the finished product at the end of its use cycle is converted back and used as a raw material to produce more of it again. Energy and matter can also be cycled in the same way in an energy and matter closed-loop system, converting matter to energy, and the energy is put back into the production of more of the matter.
Answer:
Sand
Explanation:
While the term buoyancy may confuse the reader, the question here is referring to buoyant force.
Buoyant force is the amount of pressure exerted on an object by the liquid it is in. Given by the formula
Where
= Buoyant Force
= Volume of Object submerged in the liquid
= Density of Liquid
= Force of gravity
Since in this question the swimmer with the sand is completely submerged in water, more of the volume of his preserver is under the water hence the buoyant force is greater on it than the swimmer with the Styrofoam (as part of him is not submerged in water)
Answer:
Sample Response:
Explanation:
The root beer exerts a force on all sides of the ice cream. These forces are all equal and cancel each other out. Gravity pushes downward on the ice cream. This can also be called the weight of the ice cream. Buoyant force pushes the ice cream upward. The ice cream floats because the buoyant force is greater than the weight of the ice cream.
