Final answer:

Black pavement becoming hot in the sunlight is an example of light waves being absorbed, as the pavement captures the light's energy, converting it into heat.

Explanation:

When light travels from one medium to another, some of the light is transmitted, some is reflected, and some is absorbed. An example of light waves being absorbed is when a road's black pavement becomes hot in the sunlight. This absorption happens because the pavement captures the energy of the light waves, converting it to heat, which makes the pavement hot. This process is why black-coloured surfaces heat up more in the sunlight than lighter-coloured surfaces, due to their higher absorption capacity.

This is straight from the lesson 6.01 page 5 (FLVS)

Astronauts must have their own supply of oxygen in their spacesuits during spacewalks due to the absence of breathable air in the vacuum of space, and to protect them from harmful solar radiation and the extreme temperatures of space. The suits also maintain positive pressure relative to the outside to prevent air from the vacuum of space from entering the suit if a leak occurs.

Astronauts must have their own supply of oxygen within their spacesuits during spacewalks because outer space does not have an atmosphere like the Earth which contains beneficial and breathable air; instead, space is a vacuum. This absence of atmosphere leaves astronauts exposed to the direct speed and force of solar radiation which can be harmful and potentially lethal. Their spacesuits, equipped with their own oxygen supply, not only enable astronauts to breathe but also serve as a barrier to protect them from this radiation and the extreme temperatures of space. The suit also maintains a positive pressure relative to the outside, ensuring that if a leak occurs, air will flow out of the suit, not into it from the vacuum of space.

Answer:

Thus, astronomers can identify what kinds of stuff are in stars from the lines they find in the star's spectrum. This type of study is called spectroscopy. ... From spectral lines astronomers can determine not only the element, but the temperature and density of that element in the star.

Explanation:

Scientists use spectroscopy to identify the elements present in stars by analyzing the light they emit. The distinct atomic spectra for each element acts as a fingerprint, allowing astronomers to understand a star's composition and its evolution over time.

Scientists determine the elements present in different stars by using spectroscopy to analyze the light those stars emit. Each chemical element has a unique atomic spectrum, either emitting or absorbing specific wavelengths of light, identifiable through spectroscopic techniques. By comparing the observed spectra with known spectra obtained in laboratories, astronomers can deduce the elements that make up a star. Stars primarily consist of hydrogen and helium, but the presence of heavy elements, such as iron, varies, offering insight into their composition and history.

The study of light elements like lithium, beryllium, and boron in stars, as compared to heavier ones, can illuminate the processes of stellar evolution and the creation of new stellar and planetary bodies. Information from stars' spectra, including subtle shifts due to Doppler effect adjustments for radial velocity, allows scientists to understand not only a star's chemical makeup but also its motion in space. Thus, spectroscopy is a powerful tool for uncovering the secrets of celestial bodies, from individual stars to distant galaxies.

Answer:

Magnitude (in kilogram) of the resultant force, [tex]|M| = 1958.53 kg[/tex]

Direction = 164.37°

Explanation:

The two forces exerted by the two tugboats are non zero vectors, therefore they can be expressed as:

For the 1620 kg tugboat in the direction N35degrees​W

[tex]M_{1} = 1620 cos \theta_1 i + 1620 sin \theta_1 j\\[/tex]

The direction of the force from the positive x - axis, [tex]\theta_1 = 90 - 35 = 55^{0}[/tex]

The equation above then becomes:

[tex]M_{1} = 1620 cos 55 i + 1620 sin 55 j\\ M_{1} = (1620 * 0.57) i + (1620*0.82) j\\M_{1} = 923.4 i + 1328.4j[/tex]

For the 1250 kg tugboat in the direction S50degrees​W

[tex]M_{2} = 1250 cos \theta_2 i + 1250 sin \theta_2 j\\[/tex]

The direction of the force from the positive x - axis,

[tex]\theta_2 = - (90 - 50) = - 40^{0}[/tex]

The equation above then becomes:

[tex]M_{2} = 1250 cos(-40) i + 1250 sin (-40) j\\ M_{2} = (1250 * 0.77) i - (1250*0.64) j\\M_{2} = 962.5 i - 800j[/tex]

The resultant vector will be given by:

[tex]M = M_{1} + M_{2} \\ M = 923.4 i + 1328.4j + 962.5 i - 800j\\M = 1885.9i + 528.4j[/tex]

The magnitude of the resultant is given by:

[tex]|M| = \sqrt{1885.9 ^{2} + 528.4^2 } \\|M| = \sqrt{3556618.81 + 279206.56}\\|M| = \sqrt{3835825.37} \\|M| = 1958.53 kg[/tex]

The direction will be given by :

[tex]cos \theta = \frac{a}{|M|} \\cos \theta = \frac{1885.9}{1958.53}\\cos \theta = 0.963\\\theta = cos^{-1} 0.963\\\theta = 15.63^0[/tex]

Direction = 180 - 15.63 = 164.37°

Hi,  

All of it is true. :

Uranus is a pale green planet, with 27 satellites and several rings.

Answer:

1) Charge chord resistance is 75 Ω

2) Charge chord resistance is 6.33 Ω

Explanation:

1) To answer the question, we note that the the formula voltage is found as follows;

V = IR

Therefore,

[tex]R = \frac{V}{I} = \frac{120}{1.6} = 75 \, \Omega[/tex]

2) Where the voltage, V = 19.5 V and the current, I = 3.33 A, we have;

Initial resistance R₁ = 19.5 V/(3.33 A) = 5.86 Ω

However, to reduce the current to 1.6 A, we have;

[tex]R_T = \frac{19.5}{1.6} = 12.1875 \ \Omega[/tex]

Therefore, where the resistance is found by the sum of the total resistance we have;

[tex]R_T[/tex] = R₁ + Charge chord resistance

∴ 12.1875 = 5.86 + Charge chord resistance

Hence, charge chord resistance = 6.33 Ω

(1) The resistance in the charge cord at the given standard voltage is 75 ohms.

(2) The resistance in the cord that accomplishes the given voltage and current is 6.33 ohms.

The given parameters;

The resistance in the charge cord at the given standard voltage is calculated as follows;

[tex]V = IR\\\\R = \frac{V}{I} \\\\R = \frac{120}{1.6} \\\\R = 75 \ ohms[/tex]

The initial resistance when the voltage is 19.5 V and current is 3.33 A;

[tex]R = \frac{V}{I} \\\\R = \frac{19.5}{3.33} \\\\R = 5.86 \ ohms[/tex]

The total resistance when the current in cord is calculated as;

[tex]R = \frac{V}{I} \\\\R = \frac{19.5}{1.6} \\\\R = 12.19 \ ohms[/tex]

The internal resistance is calculated as;

[tex]r = 12.19 - 5.86\\\\r = 6.33 \ ohms[/tex]

Answer:

The distance between charges is 0.33 m.

Explanation:

We have,

The charge on each sphere is [tex]2.5\times 10^{-6}\ C[/tex]

Force between charges is 0.5 N

It is required to find the distance between spheres. The force between two charges is called electrical force. The force between them is given by :

[tex]F=\dfrac{kq^2}{r^2}[/tex]

r is distance between charges

[tex]r=\sqrt{\dfrac{kq^2}{F}} \\\\r=\sqrt{\dfrac{9\times 10^9\times (2.5\times 10^{-6})^2}{0.5}} \\\\r=0.33\ m[/tex]

So, the distance between charges is 0.33 m.

Final answer:

To find the distance between two spheres with identical charges of 2.5×10-6 C experiencing a 0.50 N force, use Coulomb's Law and rearrange it to solve for the distance, which is the square root of the product of Coulomb's constant, the magnitude of the charges, divided by the force.

Explanation:

The distance between two spheres, each with a charge of 2.5×10-6 C, when the force between them is 0.50 N, can be calculated using Coulomb's Law. The formula for Coulomb's Law is F = k × (|q1×q2|) / r2, where F is the force between the charges, k is Coulomb's constant (approximately 8.99×109 N·m2/C2), q1 and q2 are the charges, and r is the distance between the centers of the two charges.

By rearranging the formula to solve for r, we get r = √(k × (|q1×q2|) / F). Plugging in the values we have:

The charge on each sphere is 2.5* 10^(-6)\ C

Force between charges is 0.5 N

It is required to find the distance between spheres. The force between two charges is called electrical force. The force between them is given by :

F=(kq^2)/(r^2)

r is distance between charges

r=\sqrt{(kq^2)/(F)} \n\nr=\sqrt{(9* 10^9* (2.5* 10^(-6))^2)/(0.5)} \n\nr=0.33\ m

So, the distance between charges is 0.33 m.
