Momentum keeps it real – in the lecture (and notes), it was claimed that the expectation value of momentum, , will always be real in spite of the imaginary operator for p. by computing −* ∗ , where the ∗ superscript denotes complex conjugate, show that the above claim is true, thus verifying that the operator for p is hermitian.

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).
