Given,
P=24kW, V=240v,
P=[tex]\frac{V^{2} }{R}[/tex], 24kW=[tex]\frac{240^{2} }{R}[/tex], Therefore R=2.4 ohm
ResistanceA 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. Ohm's Law was developed under his direction.

Hubble's law, which says simply that a galaxy's velocity (or as is sometimes plotted, its redshift) is directly proportional to its distance, also tells us something important about the state of the universe. If the universe is static and unchanging, there should be no correlation between distance and velocity.
Recessional velocity is the rate at which an extragalactic astronomical object recedes (becomes more distant) from an observer as a result of the expansion of the universe. It can be measured by observing the wavelength shifts of spectral lines emitted by the object, known as the object's cosmological redshift.

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.
What is refraction of light?Refraction of light is the bending of light rays as the cross the boundary between two media of different densities.
When light travels from a less dense to a denser medium, the ray of light is bent closer towards the normal. However, when the ray of light is travelling from a denser to a less dense medium, the ray of light is bent away from the normal.
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. Analogue, range restriction can also affect the coefficients in multiple regression

Intensity of laser beam is 72.3W/m²
Given:
average power output = 0. 250 mw
To Find:
intensity of laser beam
Solution:
First of all, we need to find the area of the circular spot, which is given by:
A = πr^2
where r is the radius of the spot, which is half the diameter, therefore
r = d/2 = 2.10mm/2 = 1.05mm = 1.05 x 10^-3m
So, the area of the spot is
A = π(1.05 10^-3m)^2 = 3.46 10^-6m²
We know that the power output of the laser is
P = 0.250mW = 2.5.10^-4W
So the intensity of the laser beam is
I = P/A = 2.5^-10 W/3.46-10^-6m^2 = 72.3W/m²

The age of the dead sea scrolls was found by carbon-14 dating. could this technique have worked if they were carved in stone tablets? explain
A Final statement or concluding statement
No because this method of dating requires a material that was once living. So, this technique wouldn’t have worked.
Why carbon - 14 dating is not reliable?Carbon 14 gradually decays into other elements. However, when a plant or animal dies, it no longer has the ability to accumulate new carbon 14, and the supply in the organism at the time of death is gradually depleted.
Scientists can calculate the time elapsed since something died from its residual carbon 14 because the rate of depletion has been accurately determined (half of any given amount of carbon 14 decays in 5,730 years).
However, scientists have long recognized that carbon dating is subject to error due to a variety of factors, including contamination from outside carbon sources. As a result, they sought methods to calibrate and correct the carbon dating method.

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.

Electrolytic cell, any device in which electrical energy is converted to chemical energy, or vice versa. Such a cell typically consists of two metallic or electronic conductors (electrodes) held apart from each other and in contact with an electrolyte (q.v.), usually a dissolved or fused ionic compound
First, look at the reaction to decided how many moles of electrons it will take:
Al3+ + 3e ------> Al(s)
It takes 3 electrons to convert 1 mole of Al3+
Next, figure out how many moles of Al metal you want:
I mole of Al mass = 26 g
1 g of Al will have = 1/26 moles
16. 22 g of al metal will have = 16.22 / 26 moles 0.624 moles

What is an electric charge?Charged material experiences a force when it is exposed to an electromagnetic field due to the physical property of electric charge. You can have a positive or negative electric charge.
Electric current is defined as the charge per unit of time.
The mathematical relation between current and the electric charge
I =Q/T
Generators are basically motors that operate in reverse—they produce electricity when rotated, instead of rotating when supplied with electricity
The conductors that come from generators must be sized, and overload protection is required. But compared to similar considerations for motors, these considerations are much simpler.
Thus, The neutral conductor on separately derived system generators must be no smaller than necessary to carry the maximum unbalanced current as specified by NEC Article 220.61.

A 5. 0-c charge is 10 m from a small test charge. what is the magnitude of the force experienced by a 1. 0 nc charge placed at the location of the test charge?
The magnitude of the force experienced by a 1. 0 c charge placed at the location of the test charge is 4.5*10^8N.
To find the answer, we have to know more about the force experienced between two charges.
How to find the force experienced between two charges?It is given that,[tex]Q_1=5C\\Q_2=1C\\r=10m.[/tex]
We have to find the force experienced between two charges,[tex]F=\frac{kQ_1Q_2}{r^2}[/tex]
where, k=8.99*10^9.
Thus, by substitution, the force will be,[tex]F=\frac{8.99*10^9*5*1}{10^2} =4.5*10^8N[/tex]
Thus, we can conclude that, the magnitude of the force experienced by a 1. 0 c charge placed at the location of the test charge is 4.5*10^8N.
