18. an example of an atom that has no
charge is one that has
o a. 3 protons, 2 electrons, and 1 neutron.
o b. 1 proton, 2 electrons, and 3 neutrons.
o c. 2 protons, 2 electrons, and 1 neutron.
o d. 3 protons, 1 electron, and 3 neutrons.

C. 2 protons, 2 electrons, and 1 neutron.

Explanation:

An atom with no charge or neutral charge is an atom with a charge of 0.

Neutrons have no charge so they do not affect it.

Electrons have a negative charge and protons have a positive charge. An equal number of protons and electrons will make the charge neutral.

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.
