SOLUTION: {{{V=-2.6+d/3}}} The electric potential, {{{V}}}, in volts, between two metal plates a distance of {{{d}}} millimetres from the left plate is given by the equation above when 0&

Question 1090858:
The electric potential, , in volts, between two metal plates a distance of millimetres from the left plate is given by the equation above when 0≤d≤15. By how many millimetres does the distance from the left plate increase for the potential to increase by 1 volt?

Solve the equation for d

This is a linear function with m = 3 being the slope.
The slope of 3 means that for every unit increase of V, the value of d will increment by 3.

Therefore the final answer is 3

Note: the domain of the equation is because of two facts
Fact 1: Plugging d = 0 into the original equation leads to V = -2.6
Fact 2: Plugging d = 15 into the original equation leads to V = 2.4
