the tab is a machine. What is the mechanical advantage of the tab? 15 cm and 5 cm

A)20.0
B)3.0
C)10.0
D)0.3

C) 10.0

The mechanical advantage of a machine is calculated by dividing the input distance by the output distance. In this case, the input distance is 15 cm and the output distance is 5 cm.

Mechanical advantage = Input distance / Output distance
Mechanical advantage = 15 cm / 5 cm
Mechanical advantage = 3

Therefore, the mechanical advantage of the tab is 10.
