Thanks for your prompt reply and assurance that my conceptual knowledge is not at risk. May also I get you to acknowledge if the information provided for #14 (A) is incomplete to deduce the energy consumed.

Answer stated is D Answer stated is DMy attempt at the solution: For the first question, the calculations are as follow: A. P=I2R = 42×12 = 192 J/s -- Missing information B. Energy = 1/2 mv2 = 15×9= 135J C. Energy = mgh = 10×10×1 = 100J D. Work done = 0J ; moving against zero friction...
