Suppose you are provided with 500 dice. Calculate the number of throws that is equivalent to one half-life and the decay constant for the process. Explanation is very much needed and appreciated. I really really need help URGENTLY. THANK YOU!!​

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
