A finite volume of gas is made up of a very large number of molecules, according to Postulate I. Despite being made up of discrete particles, gases can be treated as continuous media thanks to this assumption.
ii) According to Postulate II, gas molecules are substantially smaller than the distance between them. Treating gas molecules as point particles requires this assumption, which also makes it easier to model their behavior mathematically.

iii) According to Postulate III, gas molecules only apply force to one another when they collide. This presumption is essential to the development of the mathematical models that explain the behavior of gases and is fundamental to the kinetic theory of gases.

The formula KEe=hf−BE, where hf is the photon energy and BE is the binding energy (or work function) of the electron to the specific material, yields the maximum kinetic energy (KEe) of ejected electrons (photoelectrons).

When λ is changed to λ/4, f increases four times, increasing the energy of incident photons because f = v/λ.

The ratio of stress to strain is called Young’s modulus of elasticity (E), or the elastic modulus. Because strain/stress (gradient = x-axis/y-axis) is the graph’s gradient. Therefore, Young’s modulus would be equal to its reciprocal.

The potential gradient has an inverse relationship with the accuracy (sensitivity) of a potentiometer. The sensitivity increases with decreasing gradient. By lengthening the potentiometer wire, the potential gradient can be decreased. Therefore, a more sensitive potentiometer is indicated by a longer potentiometer wire.

The charge distribution and system geometry determine the electric intensity at the center of a uniformly distributed charge. The electric field intensity is zero at the center of a spherically symmetric charge distribution, like a uniformly charged sphere. This is because the symmetry of the distribution causes the electric field vectors from every point on the sphere to cancel each other out.

Capacitors are designed to store charge.

Since the field is created between the two charges—from the +ve charge to the -ve charge—no electric field can exist on X or Z, and the field lines will only cross at Y.
