Question

how much energy is imparted to an electron as it flows through a 8 v battery from the positive to the negative terminal? express your answer in attojoules. express your answer in attojoules to three significant figures.

Answer 1

Step-by-step explanation:

The energy imparted to an electron as it flows through a battery can be calculated using the equation:

E = qV

where E is the energy in joules, q is the charge of the electron in coulombs, and V is the voltage of the battery in volts.

One electron has a charge of approximately 1.6 x 10^-19 coulombs.

So, for a 8 V battery, the energy imparted to an electron can be calculated as:

E = (1.6 x 10^-19 C) * (8 V) = 1.28 x 10^-18 J

In attojoules, 1 attojoule is 10^-18 J, so:

E = 1.28 x 10^-18 J / (10^-18 J/attojoule) = 1.28 attojoules (to three significant figures).
