The choir club at a local school is running a field to a waterpark. there are 6 parks the club is considering. the director has asked the members to each pick three to narrow down the list of possibilities before making a final decision. how many different possibilities are there for the list of three?
a. 20
b. 150
c. 120
d. 3

The correct answer is A. 20

Step-by-step explanation:

Number of parks available for the club = 6

Capacity of the list of parks which is to be formed = 3

So, We need to select a list of 3 parks

Thus, we need to find the total number of different ways in which list of 3 parks can be formed from the total number of 6 parks.

Therefore, The correct answer is A. 20

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
