6.3 and 14.7

Step-by-step explanation:

To find how many number of trees we need we do:

10.5/5 = 2.1 trees

So Meryl needs 2.1 trees for every cabin.

To find the next answers we simply multiply 2.1 x the number of cabins, so

3 x 2.1 = 6.3

7 x 2.1 = 14.7

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

the correct answer is $7.38
