C. mechanical advantage

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.

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 ? (:
