C. mechanical advantage
Okay whats your reason? (:
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.

okasay i will need help prolly on a few more but i gotta switch computers ^.^ hold on
lol ok i will try to help
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 ? (:
