Probably a. Reactivity.
Because molecules REACT to heat and coldness by going crazy when there is heat and by freezing up when its cold
Answer:e
Explanation:
As the Pendulum swings back and forth its kinetic energy is converted into potential and Potential into kinetic .
At highest point Pendulum is momentarily at rest and thus possess all the energy in the form of Potential Energy which is converted into kinetic energy as the pendulum moves downward.
The kinetic energy is maximum at mean position i.e. at lowest point.
Thus all of the given options are true
Yes, our friend is right, because there is no contradiction to the law of conservation of mass in the above equation. It just the mass of the product is equal to the mass of reactants.. and that is shown in the equation you have presented earlier
