1. Consider the values of the time constant you got for the combination of capacitors and resistor used in Part 3 of this investigation. What is an average value considering your answers? What is the range of values you got? Is this range what you would expect given the method used? Explain, including specific ideas on what contributes to uncertainty of the value.

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

d eras and periods

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
