Question 4 of 20 Sarah is creating a corral for her horses out of fencing. She is unable to make it a circle, but she wants to get close, so she chooses a
dodecagon. In order to buy the exact amount of fencing to build the corral,
Asse
Sarah assumes that an interior angle of a regular dodecagon is (8x - 2). then the value of x is
19
21.5
10

Likewise, Sarah assumes that value of an exterior angle of the same dodecagon is (5y + 7)". then the value of y is
7.4
4.6
6.4

is it i think

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
