A person is submerged of about 97.9%.

The average density of the human body is given as 979 kg/ m³.

    Law of floatation can be defined as the volume of the liquid displaced when a body floats on the liquid surface is equal to the body submerged in the water.

As body has the stable equilibrium state, the buoyancy of the fluid will be equal to the weight.

Weight of the body floating = Weight of the body immersed in fluid

  Law of floatation = Density of the floating object / density of fluid

 As fluid is the freshwater here, the density of fluid will be 1000 kg/ m³.

                               = (979 kg/ m³) / ( 1000 kg/ m³)

                               = 97.9 %

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.

Given,

P=24kW, V=240v,

P=[tex]\frac{V^{2} }{R}[/tex],  24kW=[tex]\frac{240^{2} }{R}[/tex], Therefore R=2.4 ohm

A force that opposes the flow of current is electrical resistance, often known as resistance to electricity. It acts as a gauge for how challenging it is for current to flow in this fashion. Ohms (), which represent resistance values, are used. Electricity will move from high to low when an electron difference exists between two terminals. This flow is opposed by resistance. Lower currents occur at higher resistance levels. The opposite is also true: the current increases as the resistance decreases. The Greek letter omega (), which represents resistance, represents ohms. German physicist Georg Simon Ohm (1784–1854), who investigated the connection between voltage, current, and resistance, is the name given to the unit of resistance known as an ohm.

The difference between the observed points and the regression line points is equal to the correlation.

The strength and direction of a relationship between two or more variables are described by the statistical measure of correlation, which is given as a number. However, a correlation between two variables does not necessarily imply that a change in one variable is the reason for a change in the values of the other.

Liquid and gas  forms of water will be present in a 1. 0 l flask at 303 k containing a visible amount of liquid water(the vapour pressure of water at 303 k is 31. 8 mmHg).

Because the problem mentions that there is liquid water visible in the flask, liquid must be one of the correct options. 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.

The you see a fish off to your right is actually farther to the left in the direction you’re looking due to refraction of light.

Refraction of light is the bending of light rays as the cross the boundary between two media of different densities.

Considering the situation in seeing a fish through an aquarium. Light rays from the water which is less dense than air travels to the eyes and is bent away from the normal. Therefore, the fish seen straight ahead is actually, farther to the left.

When the range of one or both of the variables is restricted, the correlation will be decreased

Restriction of range is the term applied to the case in which observed sample data are not available across the entire range of interest.

Correlation is a statistical measure (expressed as a number) that describes the size and direction of a relationship between two or more variables. A correlation between variables, however, does not automatically mean that the change in one variable is the cause of the change in the values of the other variable.

Restricted ranges affect correlations. In fact, when the range is restricted, a peculiar phenomenon happens: the correlation coefficient goes down. The range restriction causes the standard deviation of the variable x to shrink which reduces the correlation of x to some variable y.

In order to cause electrons to be ejected from the surface of this metal you should use light of a shorter wavelength.

The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons. The phenomenon is studied in condensed matter physics, and solid state and quantum chemistry to draw inferences about the properties of atoms, molecules and solids. The effect has found use in electronic devices specialized for light detection and precisely timed electron emission.

This process is also often referred to as photoemission. In terms of their behaviour and their properties, photoelectrons are no different from other electrons. The prefix, photo-, simply tells us that the electrons have been ejected from a metal surface by incident light.

The photons of a light beam have a characteristic energy, called photon energy, which is proportional to the frequency of the light. In the photoemission process, when an electron within some material absorbs the energy of a photon and acquires more energy than its binding energy, it is likely to be ejected. If the photon energy is too low, the electron is unable to escape the material. Since an increase in the intensity of low-frequency light will only increase the number of low-energy photons, this change in intensity will not create any single photon with enough energy to dislodge an electron. Moreover, the energy of the emitted electrons will not depend on the intensity of the incoming light of a given frequency, but only on the energy of the individual photons.
