Adouble pulley with friction is being used to lift a 50kg object at constant velocity. if the force needed is 300n, what is the efficiency and the actual mechanical advantage of the pulley? 0 a. efficiency = 0.6, mechanical advantage-2 o b. efficiency-0.83, mechanical advantage-2 ° c. efficiency = 0.6, mechanical advantage = 1.67 0 d. efficiency = 0.83, mechanical advantage-1.67

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

laticia draws the diagram below to show earth’s magnetic field.

answer
