Acombination lock has a 1.1-cm-diameter knob that is part of the dial you turn to unlock the lock. to turn that knob, you grip it between your thumb and forefinger with a force of 0.66 n as you twist your wrist. suppose the coefficient of static friction between the knob and your fingers is only 0.13 because some oil accidentally got onto the knob. what is the most torque that you can exert on the knob without having it slip between your fingers?

Hen a gfci receptacle device is installed on a 20-ampere branch circuit (12 awg copper), what is the minimum volume allowance (in cubic inches) required for conductor fill for each conductor in the outlet box?

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
