Answer:
Electric generator is the device that converts mechanical energy into electrical energy
To solve this problem we will apply the definition of the ideal gas equation, where we will clear the density variable. In turn, the specific volume is the inverse of the density, so once the first term has been completed, we will simply proceed to divide it by 1. According to the definition of 1 atmosphere, this is equivalent in the English system to

The ideal gas equation said us that,
PV = nRT
Here,
P = pressure
V = Volume
R = Gas ideal constant
T = Temperature
n = Amount of substance (at this case the mass)
Then

The amount of substance per volume is the density, then

Replacing with our values,


Finally the specific volume would be


It would be adaptation because the finches live in different islands and each have different weather and resources
“Wave-B is every bit as invisible as Wave-A is.”
Using the equation:
Energy transferred = Charge x Potential difference
Rearrange for p.d:
V = E/Q
Substitute values:
V = 80/20
V = 4
