Find the apothem of an equilateral triangle with radius 8 cm.

In this question , the triangle is equilateral triangle , with radius equals to 8 cm  and we have to find the length of apotherm, a .

Using sine ratio rule,

For triangle ODC, opposite is a cm and hypotenuse is of length 8 cm .

So we will get

Multiplying both sides by 8

So the length of the apothem is 4 cm .

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

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.
