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. THANK YOU! I really really need help URGENTLY PLEASE. Explanation is highly appreciated!​

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.

The answer is a.  i hope this

100 pounds is 100 pounds no matter the object or item being weighed
