1.raphael's neighborhood kid's pool is shaped like a square with an area of 120 ft². what is the aproximate side length of the pool? (between which two numbers)
a. 9 and 10
b. 10 and 11
c. 11 and 12
d. 12 and 13

2. heather is putting together a square bulletin board for her new room, and the area of the bulletin board is 196 cm². what is the total difference around the bulletin board?
a. 14cm
b. 196cm
c. 28cm
d. 56cm

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

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
