Using what you know about the kinetic energy equation, which object would have the greater kinetic energy? Explain why in your response. A: A mouse running 3 m/s
B: An elephant running 3 m/s

kinetic energy = ½ (mass) (velocity)2

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

Time remaining 58: 10 an atom that has 84 protons and 86 neutrons undergoes a reaction. at the end of the reaction, it has 82 protons and 84 neutrons. what happened to the atom? it accepted radiation in a chemical reaction it donated neutrons to another atom in a chemical reaction it emitted an alpha particle in a nuclear reaction. it accepted protons in a nuclear reaction. mark this and retum save and exit next submit

The lab procedure involves several factors, listed below some were variable and some were constant. label each factor below v for variable ot c for constant
