Suppose you have two charges, -8.1×10^-8 C and -2.4×10^-7 C respectively, with a certain distance from each other. The electric potential at a point 6.6×10^2 m away from the greatest charge is -7.5 volts. What is the distance between the charges?

Edit the post so i can see the letters for each answer, and increase the points required so i'd be able to answer it.

Molybdeum(mo)orruthenium (ru)actually, elements with similar chemical properties as technetium would bemn, re, and bh. this is because elements in the same group/family (column) have similar chemical properties. elements in the same period (row) have the same number of energy levels (or shells).

If one were to put the y value into the equation, they could find out what x is for a certain value of y.  putting in the value of y (1), we get the equation: 1=4x-12=4xx=0.5this means that the value of x when why is 1 is x=0.5
