1. imagine the running deer has a mass of 100kg and its running at the speed if 8 m/s. what is the deer's kinetic energy in joules? 2.imagine that a bowling ball needs to be lifed 1.5 meters, and its gravitational potential energy is 90 joules. How much does the bowling ball weigh?

More; less is the correct answer

The proton has a positive charge while the neutron has no charge they both make up the nucleus of the atom while the elections have a negative charge and surround the nucleus of the atom. the protons and electrons are used to calculate the atom's mass whereas the neutrons don't affect the mass

They are both used to view parts of the cell

The answer is c i think
