Find the absolute value of the change of the gravitational potential energy (gpe) of the puck-earth system from the moment the puck begins to move to the moment it hits the spring. use 0.253 m for the displacement of the puck along the ramp and 9.80 m/s2 for the acceleration due to gravity. assume that the mass of the puck is 0.180 kg.

What type of force holds atoms together in a crystal?

What are close-toed shoes least likely to provide protection against? hydrogen gas produced during a reaction spilled water from a hot-water bath broken glass from a dropped test tube acid leaking from a cracked beaker

Brian is speaking to you and a group of friends. he explains that nuclear power plants are essentially nuclear bombs waiting to explode. this is very worrisome to your friends. which statement is best suited to discredit brian and put your friends at ease? select all that apply. -nuclear power plants and nuclear bombs both use nuclear fission to generate energy, but a nuclear power plant very precisely controls the intensity of the reaction while a nuclear bomb releases the energy in one big explosion. -nuclear power plants use nuclear fusion to generate energy, but a nuclear bomb relies on nuclear fission. since, their reactants differ, their reactions differ. -nuclear power plants have never exploded in their 60 year history. -you agree with brian's statement.
