Person A leaves his home to visit his cousin, person B, who lives 265 miles away. He travels at an average rate of 58 miles per hour. One half-hour later, person B leaves her house to visit person A, traveling at an average rate of 60 miles per hour. How long after person B leaves will it be before they meet?
it will take hour(s) for both people to meet after person B leaves.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
