Asystem contains n atoms, each of which can only have zero or one quanta of energy. how many ways can you arrange r quanta of energy when (a) n = 2, r = 1; (b) n = 20, r 10; (c) n = 2 x 1023, r = 1023?

Step-by-step explanation:

If the system contains atoms, we can arrange quanta of energy in

ways.

In this case,

                                .

Therefore,

which means that we can arrange 1 quanta of energy in 2 ways.

In this case,

                                .

Therefore,

which means that we can arrange 10 quanta of energy in 184 756 ways.

In this case,

                                .

Therefore, we obtain that the number of ways is

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
