Arobot maneuvers itself by using a laser guidance system where the positions of reflective targets, such as at points b and c, are known. by scanning the room with a laser that emanates from point a and sensing the reflections from targets b and c, the robot may compute the direction cosines of position vectors as given below. the locations of other points, such as point d at the base of the ramp, are also known, but such locations do not have reflective targets. determine the position vector from point a to point d so that the robot may move from its current position to the base of the ramp at point d. take the coordinates of point b as (0, 0, 122) cm and point c as (250, -45, 90) cm.

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.

A6.0-μf air-filled capacitor is connected across a 100-v voltage source. after the source fully charges the capacitor, the capacitor is immersed in transformer oil (of dielectric constant 4.5). how much additional charge flows from the voltage source, which remained connected during the process?
