The electric potential of a charge distribution is given by V(x) = ax2 +bx + c, where a = 12 V/m2, b = -10 V/m, and c = 62 V. At which point is the electric field equal to zero?

show the diagram then i will answer

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

cant without the picture! ?

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
