Technician A says that an anti-lock braking system pressure tester depresses the proportioning valve on some anti-lock braking systems while bleeding the brakes. Technician B says that the anti-lock braking system proportioning valve depressor allows the technician to test any pressure issue with the hydraulic control unit. Who is correct?

Two vectors are shown. which statement best compares the vectors? vector x has greater magnitude than vector y. vector y has greater magnitude than vector x. the vectors have the same displacement. the vectors have the same direction.

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
