Any object in space has a field, it's just the smaller it is the lower the force of that field. Two baseballs can be placed 1 meter apart and one of them if not both will pull the other twords it. This experiment was done on a simulation and it took 4 weeks for them to hit each other

If a hammer has a resistance arm of 3 inches and the effort arm is 15 inches. What is the mechanical advantage?

Answer:

Option D

MA=5

Explanation:

Mechanical advantage is the the ratio of the output force to the input force hence

$MA=\frac {Effort arm length}{Load arm length}$

Substituting 15 inches for the effort arm length and 3 inches for the load arm length then we obtain the mechanical advantage as

$MA=\frac {15}{3}=5$
