I need help I almost got every question wrong!

b = (20*3+11+13)/10

Step-by-step explanation:

First add the number of people on the trip

There are 3 classes

20*3 is the numbers of students since there are 20 students per class

11 teachers and 13 parents

20*3+11+13

Then divide by the number of people per boat

(20*3+11+13)/10

The number of boats needed is

b = (20*3+11+13)/10

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
