Height of the cone = 8.59 or 8.6

Step-by-step explanation:

The height is 8.59 in.

Step-by-step explanation:

V = (1/3)(pi)(r^2)h

r = d/2 = 5 in.

225 = (1/3)(3.14159)(5^2)h

225 = 26.18h

h = 225/26.18

h = 8.59 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
