An electron volt (eV) is approximately equal to 1.602 x 10^-19 joules.
To determine the number of joules in an electron volt, we can use the given charge of an electron. The electric potential is a measure of the electric potential energy per unit charge. Since the charge of an electron is approximately -1.602 x 10^-19 coulombs (C), moving an electron from an electric potential of 0 to -1 volt (-1 V) requires a change in electric potential energy of 1 electron volt.
To convert electron volts to joules, we can multiply the value of 1 electron volt by the charge of an electron. Using the given value of the electron's charge (-1.602 x 10^-19 C), the calculation becomes:
1 electron volt x (-1.602 x 10^-19 C) = -1.602 x 10^-19 joules.
Therefore, an electron volt is approximately equal to -1.602 x 10^-19 joules. The negative sign indicates that the energy change is a reduction in potential energy as the electron moves from a higher electric potential to a lower electric potential.

The quantity would be 0.5.
The price would rise to 2.
Answer:
A. The price would drop to 0.5.
Explanation:
The graph shows that for every increase of 100 units of the goods demanded, price reduces by 1 unit.
When 500 units was demanded, the price was at 1. Therefore, if 550 units are demanded, the price will reduce by half, which means the price would drop to 0.5.
