C. Frequency is a measure of how many waves pass by in one second.
Force applied by the lever to the object=2700 N
Explanation:
Mechanical advantage= 
mechanical advantage= 5.4
effort force= 500 N
we need the load force
5.4= load/500
load=2700 N
Thus the force applied by the lever to the object=2700 N
Answer:
Gravity Increases - Mass increases, distance decreases
Gravity Decreaes - Mass decreases, distance increases
Two things are needed to complerely describe a force: its strength and its direction. An arrow indicates both.
