What is the significance of the expectation value of momentum being zero in quantum mechanics?
In quantum mechanics, the expectation value of momentum being zero signifies that there is no preferred direction of motion for a particle. This implies that the particle is equally likely to be found moving in any direction, reflecting the inherent uncertainty and probabilistic nature of quantum systems.
Why does expectation value of momentum of a particle in one dimensional box box for state one comes to be zero?
Recall that, in basic quantum mechanics, the "expectation value" of a quantity is the arithmetical mean you would get if you measured that quantity innumerable times. A particle in a one-dimensional box is basically bouncing back and forth within the box, with no change in momentum between bounces. Thus, it is just likely to have momentum in one direction (let's call it "to the left") as the other direction ("to the right"). If you take several measurements of the momentum, half will have a leftward momentum, half will have a rightward momentum -- and the size of all measurements will be equal (no loss of velocity in the bounce). If you sum up all such measurements, the half going left will thus exactly cancel the other half going right. Since the sum is zero, the arithmetic mean is zero, and thus the expectation value is zero.

What statement is true about the TTL value of an IPv4 packet?

What is an example of the expectation value in quantum mechanics?
An example of the expectation value in quantum mechanics is the average position of a particle in a one-dimensional box. This value represents the most likely position of the particle when measured.
What is the z score of 1.0?
It is the value that is one standard deviation greater than the mean of a Normal (Gaussian) distribution.
What device decreases the TTL value whenever a packet traverses it?
The device that decreases the Time to Live (TTL) value whenever a packet traverses it is a router. Each time a packet passes through a router, the TTL value is decremented by one to prevent packets from circulating indefinitely in the network. If the TTL value reaches zero, the packet is discarded, which helps maintain network efficiency and prevents congestion.
