12. A car with a mass of 1,200 kg has a
velocity of 30 m/s west. What is the car's
momentum?

Answer3600kgmls

Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity. it formula = mass × velocity. so it's SI unit is = kg×m/s = kg m/s.

mass =1200

velocity=30m/s

momentum=?

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
