An old treasure map has the following instructions Stand next to the black rock and face the west. Walk20 yards and then turn 90 degrees clockwise.. Walk another 10yards and then turn 45 degrees anticlockwise.. Walk another 15yards. Reverse your direction and walk 5yards back. Turn 135 degrees clockwise and walk another 10 yards.. In which direction are you now facing? ​

the answer is c

step-by-step explanation:

the discriminant is 64 + 4*1*12 = 112

this is prime.

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
