If the temperature is lowered from 60 °c to 30 °c, the volume of a fixed amount of gas will be one half the original volume. if the temperature is lowered from 60 °c to 30 °c, the volume of a fixed amount of gas will be one half the original volume. a. true b. false

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
