<h2>Answer 1:</h2>
The gravitational force is a force that attracts any objects with mass. Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy including planets, stars, galaxies, and even light are brought toward one another.
Answer 2:
Gravity keeps things together. It is a force that attracts matter towards it. Anything with mass creates gravity, but the amount of gravity is proportional to the amount of mass.
Gravitational force is critical to our universe because with out gravitational force we cannot walk on earth, all the matter on earth cannot stay on it with out gravity. Everything will start floating in air with out gravity.
<h2>Answer 3:</h2>
Gravity is the powerful force that glues our universe together.
- One of the most noticeable effects of gravity in the solar system is the orbit of the planets.
- The planet keeps moving but is always caught up in the push-pull forces caused by the interaction of these gravitational forces. As a result, the planet begins orbiting the sun.
- The same phenomenon causes the moon to orbit around the Earth except its the Earth's gravitational force not the sun's that keeps it moving around us.
Answer:
Definition:
Biological evolution is the process through which the characteristics of organisms change over successive generations, by means of genetic variation and natural selection. It is most commonly defined as "changes in gene frequencies in populations."
A small change in genes could result in a mass epidemic. Such as the colinistists bringing yellow fever over to America.
Explanation:
Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.
Answer:
Kinetic to electric
Explanation:
The turbine blades turn because the water (possessing kinetic energy) pushes the blades. The kinetic energy in the blades turn the shaft, which is still kinetic energy (energy of movement), to power a generator. A generator has an input of kinetic energy and uses it to induce electrical energy.
