because mechanical advantage is the number of times a machine multiplies the effort force. It is calculated by MA equals resistance force divided by effort force.

C. "In physics and engineering, mechanical advantage, gearing (MA) [1] is the factor by which a mechanism multiplies the force or torque applied to it." --Wikipedia

Thanks! Soweh about that.. it turns out my mom is still setting up the other computer in the other room >.< LOL Okay other question..... A scientist is using a pulley in a laboratory. If the resistance force is 40 Newtons and the effort force is 20 Newtons, what is the mechanical advantage? A. 1 B. 2 C. 3 D. 4 Wouldnt it be B ? (:
