A three-dimensional potential well has potential U0 = 0 in the region 0 < x < L, 0 < y < L, and 0 < z < L and infinite potential otherwise. The ground state energy of a particle in What is the energy of the first excited state, and what is the degeneracy of that state? (a) 2Eo, single degeneracy
(b) 2Eo, triple degeneracy
(c) 3Fo, single degeneracy
(d) 6Eo, triple degeneracy
(e) 6Eo, single degeneracy

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

answer: carrie scored higher on the standardized test because she got the highest score out of all of them.
