Why do different elements emit different colors of light

Answers

Answer 1
Answer:

Answer:

different photonic energies
Answer 2
Answer:

Final answer:

Elements emit different colors of light based on their electron configurations and the amount of energy released.

Explanation:

Each element has a unique arrangement of electrons in its atoms. When these electrons transition from higher energy levels to lower energy levels, they release energy in the form of light. The color of light emitted depends on the amount of energy released.

For example, sodium emits yellow light because its electrons transition from a higher energy level to a lower energy level, releasing a specific amount of energy corresponding to the yellow part of the visible spectrum.

Other elements, like copper or lithium, emit different colors of light because they have different electron configurations and release energy at different wavelengths.

Answers

You just told us how long the pendulum takes to complete one cycle. That's the definition of the period. Its 1/2 second.

The frequency is the reciprocal of the period. That's 2 per second. Or 2 Hz.

The copper wire and bulb is connected in a series with 220 V electric supply. Why only an electric bulb glows where as the copper wire remains the same.Give REASON to support the answer.

Answers

-- In a series circuit, the current ( I ) is the same at every point.

-- The power dissipated by any section of the circuit is I² x Resistance.

-- The wire has very low resistance, so I²R is very low dissipated power.

-- The filament in the bulb has most all of the resistance in the circuit,
so it dissipates virtually all the power of the circuit, and certainly much
more than the wires do.

Problems with solar energy include _____. the inability of current technology to capture large amounts of the Sun's energy the inability of current technology to store captured solar energy inconsistencies in the availability of the resource lack of demand for solar energy

Answers

Problems with solar energy include the inability of current technology to capture the large amounts of the Sun's energy, the inability of current technology to store captured solar energy, and inconsistencies in the availability of the resource. Thus, the correct options are 1, 2, and 3.

What is the Solar energy?

Solar energy is the radiant light energy and the heat energy from the Sun which is harnessed using a wide range of technologies such as the solar power to generate electric energy, solar thermal energy, and the solar architecture.

Problems which are associated with the solar energy include the inability of current technology to capture the large amounts of the Sun's energy, the inability of current technology to store captured solar energy, and inconsistencies in the availability of the resource.

Therefore, the correct options are 1, 2, and 3.

First choice:  the inability of current technology to capture
large amounts of the Sun's energy

Well, it's true that large amounts of it get away ... our 'efficiency' at capturing it is still rather low.  But the amount of free energy we're able to capture is still huge and significant, so this isn't really a major problem.

Second choice:  the inability of current technology to store
captured solar energy

No.  We're pretty good at building batteries to store small amounts, or raising water to store large amounts.  Storage could be better and cheaper than it is, but we can store huge amounts of captured solar energy right now, so this isn't a major problem either.

Third choice:  inconsistencies in the availability of the resource

I think this is it.  If we come to depend on solar energy, then we're
expectedly out of luck at night, and we may unexpectedly be out
of luck during long periods of overcast skies.

Fourth choice:  lack of demand for solar energy

If there is a lack of demand, it's purely a result of willful manipulation
of the market by those whose interests are hurt by solar energy.

Which of the following universal forces is the weakest? A) electric
B) gravitational
C) magnetic
D) strong nuclear

I also need some explanation for this one 

Answers

Answer:

Option (B)

Explanation:

The gravitational force is usually defined as the force of attraction that occurs due to the presence of the object's mass. The mass of the object and the force of gravity is directly proportional to each other. At the atomic as well as at the subatomic levels, this gravitational force of gravity is comparatively so weak because the masses of these atoms, subatomic particles are extremely very small. This force has a strength of about 10^-40 and this far smaller in comparison to the strength of electromagnetism.

On the other hand, the other universal forces such as the electric force, magnetic and strong nuclear force are very much stronger than the gravitational force. The nuclear force is strongest of all, where it is 100  times stronger than the electromagnetic force and approximately 10^36 times stronger than the gravitational force.

Thus, the correct answer is option (B).
Well, electric and magnetic are actually the same in nature (as basic force in the Universe). The four, in decreasing order of strength, are:
Strong nuclear, Weak nuclear, Electric/Magnetic (in roughly the same range) and Gravitational (much weaker than Electric/Magnetic -- a magnet less than 1 kg beats Earth which is quite a lot of gigatons, roughly)

How is wave velocity calculated?

Answers

Velocity of a wave (v) = frequency (f) × wavelength (λ)As mentioned above, the velocity of a wave is related with its frequency and wavelength by the following equation. In order to find the velocity of sound using this equation, we need to know both the frequency and the wavelength of sound.
