Acircuit consists of a battery and two resistors connected in parallel. if the resistance in both resistors is doubled, and the current is kept constant, how does the voltage change?

a) the voltage is quartered
b) the voltage is halved
c) the voltage remains the same
d) the voltage is doubled

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
