Ascale model of a car is 10 in. long. the actual car is 15 ft long. what is the scale of the model?
a) 1 in. : 18 ft
b) 1 in. : 1.5 in.
c) 1 in. : 18 in.
d) 1 in. : 24 in.

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

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7
