A girl that is 4 feet tall casts a shadow that is 2 feet long. Find the height of a boy that casts a 3-foot shadow. A. 6.5 feet
B. 6 feet
C. 5.5 feet
D. 4.5 feet

B. 6 feet

Step-by-step explanation:

4 ÷ 2 = 2

6 ÷ 2 = 3

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
