An electron-volt (eV) is the amount of energy needed to move a single electron from an electric potential of 0 to an electric potential of -1 V. The charge of an electron is approximately -1. 602 x 10^-19 C. How many joules is an electron volt?

Answers

Answer 1

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.

Based on the graph, what would happen if customers demanded 550 units of this product?
The price would drop to 0.5.
The quantity would be 0.
The quantity would be 0.5.
The price would rise to 2.

Answers

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.
