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.

b. The ionization energy increases because the ratio of the protons to electrons increases.
c. The ionization energy decreases because the ratio of the protons to electrons decreases.d)The ionization energy increases because the ratio of the protons to electrons decreases.
The first and second electrons from an atom can be explained by "the ionization energy decreases because the ratio of the protons to electrons increases."
Ionizations energy, also referred as ionization potential, is the amount of energy necessary to remove an electron from an isolated atom or molecule.
The electron is just a subatomic particle with a negatively fundamental charged. Consider the nuclear charge of the atom to understand this. The greater the number of protons in the nucleus, the stronger the nucleus's attraction to electrons. This increased affinity makes removing electrons more challenging. The ionization energy reduces within a group as the atom size increases.
The ionization energy falls as the proton-to-electron ratio grows. When electrons are removed from an atom, it becomes more positive, increasing the attraction interactions between protons and neutrons. This makes removing the succeeding electrons more difficult, resulting in a larger ionization energy.
Hence the correct option is a.

Explanation:
In solids, molecules are held together due to strong intermolecular force of attraction between them. These molecules do not move past each other as they are fixed at their position. As a result, solids have definite shape and volume.
In liquids, molecules are less tightly held as a result the molecules are able to move and hence they slide past each other. Liquids do not have fixed shape and volume.
In gases, molecules are held by weak Vander waal forces. Therefore, they move rapidly from one place to another with more collisions.
Thus, we can conclude that liquid is the phase of matter which consists of particles that are held together but have the ability to flow past each other.
