The editing technique is used to indicate a passage of time, usually symbolizing a sunset and sun rise is montage .

Montages are one of the most common techniques used to show the passage of time. In motion pictures, the editing technique of assembling separate pieces of thematically related film and putting them together into a sequence.

A Montage is a series of video messages sent privately from a bunch of people who really care about you, and combined into one surprise, video gift. Most Montages are 10-30 minutes long. The longest Montage ever was 1 hour and 12 minutes long

Montages enable filmmakers to communicate a large amount of information to an audience over a shorter span of time by juxtaposing different shots, compressing time through editing, or intertwining multiple storylines of a narrative. The word “montage” derives from French — meaning “assembly” or “editing.”

Mathematical order in atomic spectra was discovered by physics pioneers Balmer, Rydberg, and Ritz.

Atomic spectra are defined as the spectrum of the electromagnetic radiation emitted or absorbed by an electron during transitions between different energy levels within an atom.

When an electron gets excited from one energy level to another, it either emits or absorbs light of a specific wavelength. The collection of all these specific wavelengths of the atom in a given set of conditions like pressure, temperature, etc. is the atomic spectra of atoms. There are three types of atomic spectra and they are :

Using the Rydberg formula, it becomes easy to calculate the spectral lines. Following is the formula:

[tex]\begin{array}{l}\frac{1}{\lambda }=RZ^{2}(\frac{1}{{n}’^{2}}-\frac{1}{n^{2}})\end{array}[/tex]

Where,

R is the Rydberg constant (1.09737*107 m-1)

n is the upper energy level

n’ is the lower energy level

By using the equations for parabolic motion, we proceed to present the answers for the paragraph seen in the picture: a) t ≈ 0.553 s, b) s = 2.212 m, c) s = 11.060 m.

A system is on parabolic motion if such system can be represented as a particle, that is, a system whose geometry is negligible, and its motion is a combination of horizontal movement at constant velocity and vertical uniformly accelerated movement due to gravity and all viscous and rotational effects are negligible.

The time required for the droplet to reach the ground is:

1.5 m = (1 / 2) · (9.807 m / s²) · t²

t = √[2 · (1.5 m) / (9.807 m / s²)]

t ≈ 0.553 s

And the horizontal distance traveled by the droplet is:

s = (4 m / s) · (0.553 s)

s = 2.212 m

Now, we apply the same procedure for the case of sneezing person:

1.5 m = (1 / 2) · (9.807 m / s²) · t²

t = √[2 · (1.5 m) / (9.807 m / s²)]

t ≈ 0.553 s

Charge appeared on the plates of a 6.0 μf capacitor when it is charged to 40V is 240μC.

Capacitance of the capacitor is determined by the area of the plate of Capacitor and distance between the plates of capacitor.

Capacitor is dependent on the area of the plates, distance between the plates and medium present between the plates.

It is not dependent of the charge and voltage across the capacitor.

We know that Q = CV, where Q is the charge on capacitor, C is the Capacitance and V is the voltage applied across the capacitor.

Q = 6 × 10⁻⁶ × 40

The first moment of the total cross-sectional area taken about the neutral axis must be zero.

A member that resists bending has a neutral axis in its cross-section along which there are no longitudinal stresses or strains. The neutral axis lies at the geometric centroid if the section is symmetric, isotropic, and does not curve before a bend. The neutral axis is not under any strain. Therefore, the neutral axis has no bending moment. Because the neutral axis is not affected by the applied stresses, there is no bending stress. At the neutral axis, no stress is created. The line in the cross-section of a beam where there is neither longitudinal compression nor tensile stress is known as the neutral axis for that beam. The neutral axis is typically regarded in the study of wood beams to be at the centroid of the beam.

The first moment of the total cross sectional area taken about the neutral axis must be zero.

As with non-composite beams, the neutral axis (NA) is the location where the bending stress is zero. The location of the NA depends on the relative stiffness and size of each of the material sections.

Generally, the NA location is determined relative to the bottom surface of the beam. However, this is not mandatory, and the location can be relative to any location. If the bottom is used, then the NA axis is a distance "h"

The distance h can be determined by recalling that the stresses through the cross section must be in equilibrium.

Additionally, liquid water has a vapour pressure of 31.8 mmHg at the given temperature, meaning there will 31.8 mmHg of gaseous water present as well, so the correct answer is liquid and gas.

Vapour pressure or equilibrium vapour pressure is defined as the pressure exerted by a vapour in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. The equilibrium vapour pressure is an indication of a liquid's evaporation rate.

It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapour pressure at normal temperatures is often referred to as volatile. The pressure exhibited by vapour present above a liquid surface is known as vapour pressure.

As the temperature of a liquid increases, the kinetic energy of its molecules also increases. As the kinetic energy of the molecules increases, the number of molecules transitioning into a vapour also increases, thereby increasing the vapour pressure.
