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.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

I'm pretty sure the answer is c
