A lever with a mechanical advantage greater than 1 is used to lift a larger load.
A beam or stiff rod is pivoted at a fixed, or fulcrum, to form a simple machine known as a lever. A stiff body that can rotate about a point on itself is called a lever. The three types of levers are categorised according to where the fulcrum, weight, and effort are located.
Mechanical advantage is the relationship between a machine's capacity to lift a load and the effort required to operate it. A machine is said to be a force multiplier if its mechanical advantage is larger than 1.
The effort arm and load arm of the lever are the same length when the mechanical advantage is equal to 1. Levers are employed to obtain an advantage when the mechanical advantage is less than 1.
Thus, A lever with a mechanical advantage greater than 1 is used to lift a larger load.

Explanation:
b. atomic mass.
c. molecular size.
d. molecular mass.
a. 0.61 years
b. 0.76 years
c. 1.24 years
d. 1.39 years
Answer:
b. 0.76 years
Explanation:
Mercury is the closest planet to the Sun and the Earth is the third planet from the Sun.
The orbital period of the Earth is 1 year.
Orbital period of the Mercury is 88 days = 0.24 years (Earth years)
Thus, the difference between the orbital periods of Mercury and Earth is
1 year - 0.24 years = 0.76 years
Thus, the correct option is b.
