Can someone help me ?

24

Step-by-step explanation:

Draw radius lines to each point of intersection (P, K, and M).  These radius lines are perpendicular to the tangent lines.  Since the radius lines are equal length, the quadrilaterals formed are kites.  Therefore, the other pair of legs of the kite must also be equal.

That means that if OP = 3, then OM = 3.  And if JP = 2, then JK = 2.  LK = 9 − 2 = 7, so LM = 7.

The perimeter of the triangle is therefore 3 + 3 + 2 + 2 + 7 + 7 = 24.

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

the answer is d
