The de Broglie wavelength of which of the following objects would be smallest if the objects had the same velocity?
d,
The de Broglie wavelength of matter is proportional to Planck's constant and inversely proportional to the momentum of the particle. If all the objects had the same velocity, this one would have the smallest wavelength because its momentum would be smallest

Suppose you find a rock that contains 10 micrograms of radioactive potassium-40, which has a half-life of 1.25 billion years. By measuring the amount of its decay product (argon-40) present in the rock, you conclude that there must have been 80 micrograms of potassium-40 when the rock solidified. How old is the rock?
A) 3.75 billion years B) 1.25 billion years C) 2.5 billion years D) 5.0 billion years
