Answer: The Total Displacement between City A and City B is 530 KM
Explanation: The Explanation to the Answer is simple you have to subtract City B To City A
A. 131 V
I got it right on the quiz
When the computer is on the circuit has positive and negative charges it will move fluenlty to get the power when it is in on position.
Slope of a curve Y plotted against X is mathematically given as

now here we can see that if similarly graph is plotted against distance and time then slope is given as

here we can say that above is ratio of small distance and very small interval of time.
so here we can say that this ratio of distance and time for very small interval of time is known as instantaneous speed of the object which is falling freely under gravity.
So here slope of the graph will represent the speed at a given instant.
Answer:

v=343m/s
Explanation:
We have to take into account the expressions

if we assume that 256Hz is the fundamental frequency we have

and for wavelength

hope this helps!!
