The light from the green glow stick held by the Olympic sprinter will appear redshifted.

The phenomenon of redshift occurs when the source of light is moving away from the observer. In this case, as the sprinter is running towards you, the distance between you and the glow stick is decreasing over time. This decrease in distance causes a Doppler shift in the frequency of the light emitted by the glow stick.

Since the light is redshifted, its wavelength increases and the frequency decreases compared to its original emitted frequency. As a result, the light that reaches your eyes appears more towards the red end of the visible spectrum.

It is important to note that the color of the glow stick itself remains the same, but due to the relative motion between the source (the sprinter) and the observer (you), the light undergoes a change in frequency and appears redshifted.

This phenomenon is similar to the redshift observed in cosmology, where the light from distant galaxies appears to be redshifted due to the expansion of the universe.

Answer: "Migrating", You're welcome

According to special relativity, one can travel at increased rates. However, this is only possible when moving at very high speeds approaching the speed of light. When an object moves at high speeds, the time slows down, and the length of the object appears to be shortened.

These observations are known as time dilation and length contraction. Time dilation refers to the difference in the elapsed time measured by two observers, where one is stationary, and the other is moving at a constant velocity relative to each other. The faster the moving observer, the slower time appears to be for them. Length contraction, on the other hand, refers to the phenomenon where an object appears to be shorter in length when it's moving at high

This effect is more noticeable as the speed of the object approaches the speed of light. As a result, traveling at very high speeds can allow one to cover great distances in less time, which can be used for space exploration and other scientific research. However, it's worth noting that the effects of relativity are only noticeable at very high speeds, which are currently impossible to achieve with our current technology.

3 stages of starting resistances

A circuit's opposition to current flow is measured by its resistance. The Greek letter omega () stands for ohms, which are used to measure resistance. Georg Simon Ohm (1784–1854), a German physicist who examined the connection between voltage, current, and resistance, is the subject of the name "Ohm." Many parts have a set resistance value, including heating elements and resistors. In manuals or on nameplates of components, these values are frequently printed for reference.

If there is a tolerance listed, the measured resistance value must fall within the given resistance range. A issue is typically indicated by any appreciable change in a fixed-resistance value.

Although the word "resistance" may sound bad, it has positive uses in electricity. In an active circuit, resistance cannot be measured.

The hydronium ion concentration in the HCl solution with a pH of 4.65 is approximately 2.2 x 10⁻⁵ M. On the other hand, the hydroxide ion concentration in the NH₃ solution is approximately ≈ 2.2 x 10⁻⁵ M

To calculate the hydronium ion (H3O+) concentration in a solution of HCl with a pH of 4.65, you can use the formula: pH = -log [H3O+].

First, you'll need to rearrange the formula to solve for [H3O+]. You can do this by taking the inverse logarithm (antilog) of both sides:
[H3O+] = 10^(-pH)

Now, plug in the given pH value of 4.65:
[H3O+] = 10^(-4.65)

Calculating the value, you get:
[H3O+] ≈ 2.2 x 10⁻⁵ M

So, the hydronium ion concentration in the HCl solution with a pH of 4.65 is approximately 2.2 x 10⁻⁵ M.

The pOH is defined as the negative logarithm (base 10) of the hydroxide ion concentration ([OH-]).

The relationship between pOH and [OH-] is as follows:

pOH = -log[OH-]

To find [OH-], we rearrange the equation:

[OH-] = 10^(-pOH)

Given a pOH of 4.65, we can calculate the hydroxide ion concentration as follows:

[OH-] = 10^(-4.65)

[OH-] ≈ 2.2 x 10⁻⁵ M

The hydroxide ion concentration in the NH₃ solution is approximately ≈ 2.2 x 10⁻⁵ M (moles per liter)

The mirror displacement d is 317.12 nm. In a Michelson interferometer, interference fringes are created due to the interference of two beams of light.

A Michelson interferometer is a device used to measure small changes in the distance between two mirrors. It consists of a beam splitter, two mirrors, and a detector. One beam of light is split into two and travels to the mirrors, where they are reflected back towards the beam splitter. The two beams of light then recombine at the detector, creating an interference pattern.

When one of the mirrors is moved, the interference pattern shifts. The amount of shift depends on the distance moved and the wavelength of the light being used. By measuring the shift in the interference pattern, we can determine the displacement of the mirror.

In this problem, we are given that 250 interference fringe shifts were counted when the mirror was moved a distance d. The wavelength of the light being used is 632.8 nm.

Each interference fringe shift corresponds to a change in the path difference between the two beams of light by one wavelength. So, the total change in the path difference is 250 times the wavelength of the light:

250 × 632.8 nm = 158,200 nm

Therefore, the mirror displacement d is 158,200 nm. However, this displacement is in both directions (i.e., the mirror moved back and forth). To find the displacement in just one direction, we divide by 2:

d = 158,200 nm / 2 = 79,100 nm

Therefore, the mirror displacement d is 79,100 nm in one direction.

Given: mass of ice = 30g, specific heat of ice = 336 Jg^-1K^-1, specific heat of water = 4186 Jg^-1K^-1

Let x be the heat energy supplied to melt the ice. Heat energy required to raise the temperature of 30g of ice from 0°C to 0°C (its melting point) is given by: Q1 = mass x specific heat of ice x change in temperature, Q1 = 30g x 336 Jg^-1K^-1 x (0 - 0) = 0 J. Since 80% of the heat supplied completely melts the ice, the remaining 20% of the heat energy supplied is used to raise the temperature of the melted ice (now water) from 0°C to 0°C: Q2 = 0.2 x total heat energy supplied, Q2 = 0.2 x x. The total heat energy supplied is given by: total heat energy supplied = Q1 + Q2, x = (total heat energy supplied - Q1)/0.2, x = (336 Jg^-1K^-1 x 30g - 0)/0.2

x = 201600 J. Therefore, the total heat energy supplied to melt the ice completely to water at 0°C is 201600 J.
