An electric motor raises a 41.6-pound-force platform loaded with 7.55-pound-force bags of calcium carbonate to 15 feet above ground level in 40 seconds on Mars. Gravity on Mars is 3.7 m/s/s. Motor has 65% efficiency and is wired to a 110-volt circuit that has a 15-ohm resistor. What is the maximum number of bags that can be lifted with the electric platform (round down to the number of whole bags)?
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
