Calculate the slope of the 25-coil line and the 50-coil line to determine the average number of paper clips that a 1 v battery would pick up.

b

explanation:

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

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
