Select the correct answer.
Which characteristic is a property of water?

A. It is made of polar molecules.

Explanation:

A polar molecule refers to a molecule that has a covalent bond but has an uneven distribution of electrons due to an atom in the molecule having strong electronegativity which will attract more of the electrons from the other atom.

Water is such a molecule because Oxygen has strong electronegativity which leads to electrons being pulled to it.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
