Find ∠MPN

Help me please

Step-by-step explanation:

Line is a diameter of the circle because it passes through the circle's center O. Therefore, arc must be 180 degrees, as these are 360 degree in a circle.

We can then find the measure of arc :

Arc is formed by angle . Define an inscribed angle by an angle with a point on the circle creating an arc on the circumference of the circle. The measure of an inscribed angle is exactly half of the measure of the arc it forms.

Therefore, the measure of must be:

Similarly, the measure of must be:

Angles and form angle , which is one of the three angles in . Since the sum of the interior angles of a triangle add up to 180 degrees, we have:

89

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
