During a lighting discharge, 30C of charge move through a potential difference of 1.0 X 10^8V in 2.0X10^-2s. The energy released by this lighting bolt is:
a)1.5 X 10^11 J
b) 3.0 X 10^9 J
c) 6.0 X 10^7 J
d) 3.3 X 10^6 J
e) 1500 J
Ok I am not really sure what equation to use for this problem. I went through the equations and I still am not sure.
What is an electron volt is:
My answer:
is a unit of energy. It is the amount of kinetic energy gained by a single unbound electron when it passes through an electrostatic potential difference of one volt
Thank you for any help
Your definition of an electron volt is correct.
The answer to the multiple-choice problem is (b) (Energy = voltage x charge)
To calculate the energy released by the lightning bolt, you can use the formula:
Energy = Voltage x Charge
In this case, the voltage is given as 1.0 x 10^8 V and the charge is given as 30 C. Plugging in these values into the formula, you get:
Energy = (1.0 x 10^8 V) x (30 C)
Multiplying the voltage and charge, you get:
Energy = 3.0 x 10^9 J
So the energy released by the lightning bolt is 3.0 x 10^9 Joules. Therefore, the correct option is (b) 3.0 x 10^9 J.
To calculate the energy released by the lightning bolt, we can use the equation: energy = voltage x charge.
Given:
Charge = 30C
Voltage = 1.0 x 10^8 V
Substituting these values into the equation, we get:
Energy = (1.0 x 10^8 V) x (30C)
Energy = 3.0 x 10^9 J
Therefore, the energy released by the lightning bolt is 3.0 x 10^9 J, which corresponds to option (b).
