The hydrogen line at 656.46 nm shifts to about 655.80 nm if a star is traveling 300 km/s toward Earth.

Using the Doppler Effect to Determine the Wavelength Shift

Use the Doppler shift formula for wavelengths:

Plugging in the values:

Calculate the ratio:

Evaluate the square root:

Compute the shifted wavelength:

The 656.46-nm line would shift to approximately 655.80 nm if the star were moving towards Earth at 300 km/s.

Complete question:

Suppose that you'd like to find out if a distant star is moving relative to the earth. The star is much too far away to detect any change in its brightness as it moves toward or away from the earth. Instead we can use the Doppler effect to determine its relative speed. For this problem we are going to look at the spectral lines from hydrogen, specifically the one with a wavelength of 656.46 nm. Even at such low fractions of the speed of light these stars are moving quite quickly (thousands of kilometers a second) compared to the standard velocity dispersion in the Milky Way galaxy (which is around 300 km/s). Suppose the star was actually moving toward the earth at a more reasonable 300 km/s. What wavelength I would the 656.46-nm line move to? Use 299, 792 km/s for the speed of light. Express your answer in nanometers to five significant figures.

The total resistance in the parallel circuit with three 10-ohm resistors and a 15-volt battery is approximately 3.33 ohms. The total current through the circuit is approximately 4.50 amps.

To calculate the total resistance in a parallel circuit with three resistors of 10 ohms each, we use the formula for parallel resistance:

[tex]\frac{1}{R_{\text{total}}} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3}[/tex]

Substituting the values:

1/Rtotal = 1/10 + 1/10 + 1/10

1/Rtotal = 3/10

Therefore, Rtotal = 10/3 = 3.33 ohms

Next, we calculate the total current using Ohm's Law:

I = V/Rtotal

Given the battery voltage is 15 volts:

I = 15/3.33 ≈ 4.50 amps

The total resistance in the parallel circuit with three 10-ohm resistors and a 15-volt battery is approximately 3.33 ohms. The total current through the circuit is approximately 4.50 amps.

Answer:

K = 6.02 × 10⁻¹⁹ J

Explanation:

The momentum (p) of an electron is its mass (m) times its speed (v).

p = m × v

v = p / m = (1.05 × 10⁻²⁴ kg.m/s) / 9.11 × 10⁻³¹ kg = 1.15 × 10⁶ m/s

We can find the kinetic energy (K) using the following expression.

K = 1/2 × m × v²

K = 1/2 × 9.11 × 10⁻³¹ kg × (1.15 × 10⁶ m/s)²

K = 6.02 × 10⁻¹⁹ J

early plants added oxygen to the atmosphere. They did this by photosynthesis process by absorbing the carbon dioxide from the atmosphere and giving away oxygen in return.

This was important because life is not possible without oxygen present in the atmosphere.

They consumed the carbon dioxide from the atmosphere and reduced the temperature of the planet also.

Using the equation for the speed of light, we find that the wavelength of a radio wave broadcasting at 102.1 MHz frequency in Springfield is approximately 2.94 meters.

The length of a wave, often termed wavelength, can be deduced if the frequency is known, using the formula of the speed of light, which is wavelength times frequency (or c = λν). In this equation, 'c' signifies the speed of light (3 x 10^8 m/s), 'λ' is the wavelength, and 'ν' is the frequency. Given frequency = 102.1 MHz = 102.1 x 10^6 Hz, we can rearrange the formula to find the wavelength: λ = c/ν = 3 x 10^8 m/s / 102.1 x 10^6 Hz = 2.94 m. Therefore, the length of the wave is approximately 2.94 meters.

The electron will reach the origin first due to its greater acceleration, which is a result of its much smaller mass compared to the proton, despite the forces on both particles being equal in magnitude.

The question is asking which particle, a proton at x = -d or an electron at x = +d that are released simultaneously under the influence of electrostatic force, will reach the origin first. According to Newton's second law, force equals mass times acceleration (F = ma). Because the proton and the electron have equal and opposite charges, the magnitude of the force acting on them due to their electrical interaction will be the same. However, the mass of the proton is much greater than that of the electron, resulting in much smaller acceleration for the proton. Consequently, the electron, given its smaller mass and therefore larger acceleration, will reach the origin first.

Final answer:

A plastic comb can attract small bits of paper due to the electrostatic charge created by friction. This effect is reduced in moist air as humidity conducts the charge away.

Explanation:

When a plastic comb is run through hair, it can attract small bits of paper. This is due to the electrostatic charge that is created by friction when the comb is dragged against the hair. The comb becomes negatively charged as electrons are transferred from the hair to the comb, resulting in an electrostatic force that can attract neutral objects, such as pieces of paper.

If you repeat the experiment in a moist environment, such as a bathroom after a shower, you may observe that the electrostatic effect is reduced. This is because water molecules in the air increase the humidity, which conducts the charge away, thereby neutralizing the electrostatic effect more rapidly than in dry air.

Torn paper may be more effective than cut paper because the tearing process can create more irregularities and protrusions on the edges of the paper, providing more opportunities for the electric force to act upon these points compared to the relatively smooth edges of cut paper.

To find the velocity of a 20-kg block descending 0.5 m, use conservation of energy, equating the potential energy lost by the block to the kinetic energy gained by the block and the rotational kinetic energy of the spool. Determine kinetic energy and rotational energy using the block's mass, spool's radius of gyration, and their shared velocity.

To determine the velocity of the 20-kg block after it descends 0.5 m, we can use the principles of conservation of energy. The system consists of a spool and a block, and since the block is descending, gravitational potential energy is being converted into kinetic energy and rotational energy of the spool.

We know that the potential energy (PE) lost by the block is equal to the kinetic energy (KE) gained by the block plus the rotational kinetic energy (RKE) gained by the spool:

PE = KE + RKE

PE of the block = m·g·h, where m is the mass of the block, g is the acceleration due to gravity (9.81 m/s2), and h is the height descended (0.5 m).

KE of the block = 1/2 m·v2, where v is the velocity of the block we want to find.

RKE of the spool = 1/2 I·ω2, with I being the moment of inertia of the spool and ω the angular velocity. Since the spool and the block are connected, ω = v / r, where r is the radius of the spool.

Using the radius of gyration ko, the moment of inertia I for the spool is I = mspool·ko2. By substituting all these expressions into the energy conservation equation and solving for v, we can find the velocity of the block.
