Who is correct? Tech A says that bleeding an electronic brake control system is just like bleeding a non–electronic brake control system. Tech B says that if air is allowed into the electronic brake control system, it can become trapped in the hydraulic control unit, requiring a scan tool to operate the solenoid valves to help bleed the air from the electronic brake control system.

A. Tech A
B. Tech B
C. Both Techs A and B
D. Neither Tech A nor B

C. Both Techs A and B

Explanation:

Bleeding motor vehicle braking system is nothing but process of removing of air bubble from the fluid line. It can be in either brake fluid line of the diesel injector line. Bleeding in most ABS cars is like bleeding in non-ABS vehicles, but a scan device would be needed to open the valves and pull fluid out if the air gets stuck in the pipe.

Hence, we can say both the Technician are correct.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
