The following diagram shows two hockey players who were initially at rest on ice (that is, a horizontal, frictionless surface) pushing off each other. Only the force with
which they push off each other contributes to their final speed..
If the 70.0-kilogram hockey player is moving to the left with a speed of 4 meters per
second, then the 140.-kilogram hockey player is moving to the right at what speed?

What happens to atoms and chemical bonds during a reaction?

Will you chech and finish these for me, because i am stumped with them.

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
