Assuming that the power plant for the electricity is 15 km away and uses 00-gauge copper wire (diameter 9.266 mm), how much power is dissipated in transmission (remember to count the return wire), if the power plant is directly providing the 110-v? (to be more precise, the power plant is providing the voltage it needs to provide, so that the voltage at the dorm room is 110 v.)

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

i think the answer is a and b

i wish you luck
