Answer: You could if you had a special fire letting out UV light, but if not, you'd probably get burned first.

Explanation:

Fire does emit UV, which causes tanning, but it also emits a lot of other wavelengths, including infrared which is primarily responsible for heating. If you build a really big fire, one that would emit enough UV to tan, it would also emit a huge amount of infrared which will burn you sooner than you getting a tan.

No, you cannot get a tan from a campfire. A tan is a result of exposure to ultraviolet (UV) radiation, specifically UVB rays, which are primarily emitted by the sun. UVB rays penetrate the skin and stimulate the production of melanin, a pigment that darkens the skin as a protective response.

A campfire does not emit significant amounts of UV radiation. The light emitted by a campfire is primarily in the visible spectrum, which does not have the same wavelength as UVB rays. Therefore, sitting near a campfire will not provide the necessary UV radiation to induce tanning.

Campfires can emit infrared radiation, which can generate heat and potentially cause burns or damage to the skin if one is too close for an extended period.

Taking into account the Gay-Lussac's Law, the pressure will increase by a factor less than three.

Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions against the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.

In summary, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.

Mathematically, Gay-Lussac's law indicates that the ratio of pressure to temperature is constant:

[tex]\frac{P}{T} =k[/tex]

Studying two different states, an initial state 1 and a final state 2, it is satisfied:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case, a given mass of gas in a rigid container is heated from 100 ° C to 300 ° C, that is, it is heated from 373 ° K to 573 ° K. This indicates that the temperature is increasing by a factor less than three. Since pressure is directly proportional to temperature, pressure must increase in the same proportion.

Finally, the pressure will increase by a factor less than three.

Answer:

Buoyancy is the ability or tendency of an object to float in a fluid: a liquid or a gas. This happens because fluid pressure increases with depth. According to Archimedes' Principle, the buoyant force on a submerged object is equal to the weight of the liquid displaced by the object.

The object's weight would be the greatest:

C. on the sun, this can be accounted on the Earth's gravity

At 12 PM, when the Sun is straightforwardly beneath, it pulls on an item in a similar course as the draw of the Earth; around early afternoon, when the Sun is straight above, it pulls on an article toward a path inverse to the draw of the Earth.

Thus, all articles ought to be heavier around evening time than they are at the day. Sun's gravitational draw on earth-bound objects is around 0.0006 of earth's gravity.

Hence, option c is correct.

Answer:

Vascular plants are successful due to better transportation for water, nutrients and reproduction.

Explanation:

I got it right at school and hope this helps you learn to STUDY.jk

According to scientists, the evolution of pollinators made vascular plants the most successful land plants for two major reasons:

Plants with seeds, including flowering plants and conifers, produce pollen grains as a component of their reproductive process. They are often carried by wind or pollinators, such as bees, to the female reproductive organs of the same or different plant species, where they can fertilize female gametes (egg cells) and begin the development of seeds.

They carry the male gametes (sperm cells) of the plant. Many plant species depend on pollen grains for successful reproduction, and these grains have evolved a variety of forms, sizes, and surface features that make them easier to disperse and be recognized by pollinators.

Therefore, according to scientists, the evolution of pollinators made vascular plants the most successful land plants for two major reasons:

Answer:

765 g Co(NH₃)₆Cl₃

General Formulas and Concepts:

Explanation:

Step 1: Define

2.86 mol Co(NH₃)₆Cl₃

Step 2: Define conversions

Molar Mass of Co - 58.93 g/mol

Molar Mass of N - 14.01 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of Co(NH₃)₆Cl₃ - 58.93 + 6(14.01) + 18(1.01) + 3(35.45) = 267.52 g/mol

Step 3: Dimensional Analysis

[tex]2.86 \ mol \ Co(NH_3)_6Cl_3(\frac{267.52 \ g \ Co(NH_3)_6Cl_3}{1 \ mol \ Co(NH_3)_6Cl_3} )[/tex] = 765.107 g Co(NH₃)₆Cl₃

Answer:

Electron shielding is when the inner electrons shield the outer electrons from the full force of the nucleus

Answer:

Conduction

Explanation:

Answer:

The atomic mass is 101.

Explanation:

Protons and neutrons are the only particles that contribute to mass. Electrons do have a mass, but it's so miniscule and insignificant that it doesn't contribute to the mass of an atom. In every instance of calculating atomic mass, add the number of protons to the number of neutrons.

Therefore,

44 + 57 = 101

number of protons + number of neutrons = atomic mass

Also, there can never be a negative amount of protons or neutrons, so if you get a negative number, there's something wrong.

Bonus Information:

Don't confuse mass with charge! As it says in its name, neutrons are neutral or have no charge. Protons (+) and electrons (-) are the only particles that have a charge, so calculating that would be different.

If you were calculating the atomic charge with the same numbers, your answer would be:

44 - 42 = 2

Charge = +2

What To Remember:

M = p + n

C = p - e

C = atomic charge, M = atomic mass, p =protons, n = neutrons, e = electrons

Standard International system is a system is used to measure physical properties.

The International System of Units (SI), is commonly known as the metric system. This system is used as the international standard for measurement. Most scientists use the International System of Units which is also known as the metric system in order to measure physical properties of elements. The metric system is a system of measurement that uses meter as base units of length (distance), liter for volume, and , and gram for weight or mass. We use units that are derived from the metric units in order to measure smaller or larger quantities.

So we can conclude that Standard International system is a system is used to measure physical properties.
