Answer:
There is no force of attraction between you and Mars
Explanation:
Newton's universal gravitation law is generally described as each particle attracts any other particle in the universe in which the the sum of its masses is directly proportional to the force and force is inversely proportional to the square of the distance between its centres.
How strong this attraction is depends on the size of the objects (mass) and how far apart they are. Human attracts to the earth surface because of the smallest distance between them.
While mars and other planets have very less forces exerted on earth due to the distance. Gravitational force between earth and sun keeps the earth to rotate in its orbit and provide a large gravitaional pull, while mars exerts very less frce on earth due to it distance from sun.
So due to large distance resulting in less gravitaional pull, humans do not attract towards Mars.
people do not use water correctly and waste it
Answer: It shows the evolution of mutations. Throughout the lifetime of animals and humans depending on their way of life and how they life it they will slowly mutate into a different animal to be able to life that way..
