It bounces off one another and goes back in forth
Answer:
a. Stored energy is potential energy, and energy of motion is kinetic energy
Explanation:
The correct option is - a. Stored energy is potential energy, and energy of motion is kinetic energy.
Reason -
Potential energy is stored energy, whereas kinetic energy is the energy of moving things.
- Kinetic energy is energy possessed by an object in motion.
- The energy associated with position is called potential energy .

Y
Explanation:
The fulcrum is the point where the scissor blades are joined together. The force or effort is the end or handle of the scissors. The parts of a pair of pliers are similar to the scissors.
Answer:
-24.76 kJ/mol
Explanation:
given,
mass of solid magnesium burned = 0.1375 g
the temperature increases by(ΔT) 1.126°C
heat capacity of of bomb calorimeter (C_{cal})= 3024 J/°C
heat absorbed by the calorimeter




heat released by the reaction


energy density will be equal to heat released by the reaction divided by the mass of magnesium
Energy density = 
Energy density = -24.76 kJ/mol
heat given off by burning magnesium is equal to -24.76 kJ/mol
