A pyramid has a square base with side s. the height of the pyramid is 2/3 that of its side. what is the expression for the volume of the pyramid? ~~~ A. V=2s²
B. V=2s³
C. V=2/3s²
D. V= 2/9s³
E. V=1/3s³​

Step-by-step explanation:

Volume of square based pyramid:

Given

Substitute

Correct choice is D

volume of pyramid = 2/9s³

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
