There are 6 students in a classroom with 8 desks. how many possible seating arrangements are there? (the answer isn't 48 or 2, i tried that)

20160

Step-by-step explanation:

Given : There are 6 students in a classroom with 8 desks.

Since here order matters , we use permutations.

The number of permutations of n objects taken r at a time is calculated by the following formula:

Then , the number of possible seating arrangements are :

Therefore, the number of possible seating arrangements are 20160.

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
