Color
Explanation:
Only color out of the listed observations is the qualitative observation. Qualitative observations are usually carried out using our senses.
- Sense of touch makes us feel the texture of particular subject.
- Sense of smell gives different types of scents and odors.
- Sense of sight helps us to identify different colors and appearances in a study.
- Sense of taste helps to know if something is bitter, sweet or sour.
- Sense of hearing helps to know how audible something it.
Qualitative observations does not involve the use of numbers.

<u>Answer:</u>
The disposal method used for high-level nuclear waste Concentrate and contain
<u>Explanation:</u>
High intensity nuclear waste is an underlying issue for the world where the generated nuclear waste is one side very hazardous and on other side would help us in many viable processes but the negative sides of a consequence just outnumber the positive sides of the situation.
Concentrate and contain is a waste disposable method which enables the nuclear waste to be preserved and isolated and later be used when the time comes. Other methods would not be suggested because they could cause a huge amount of dangerous radioactivity in oceans which is often harmful for people.
Answer: heat
Explanation:
Infrared radiation is popularly known as "heat radiation",[21] but light and electromagnetic waves of any frequency will heat surfaces that absorb them. Infrared light from the Sun accounts for 49%[22] of the heating of Earth, with the rest being caused by visible light that is absorbed then re-radiated at longer wavelengths
Answer:
The wavelength, λ, of a photon that has an energy of E = 3.92×10⁻¹⁹ J is 5.054*10⁻⁷ m
Explanation:
The wavelength is defined for every periodic wave, that is, for the type of wave that repeats itself with exactly the same shape every given interval of time. It is the distance between two points from which the wave repeats.
Radiation is the emission, propagation and transfer of energy in any medium in the form of electromagnetic waves or particles.
The energy carried by electromagnetic radiation travels by waves. This energy is transmitted grouped in small "quanta" of energy called photons. The energy of a photon is measured in Joules (J) and is
Being:
- E=3.92×10⁻¹⁹ J
- h= 6.626×10⁻³⁴ J⋅s (Planck's constant)
- c = 2.99×10⁸ m/s (the speed of light)
- wavelength=?
and replacing:
you get:
wavelength= 5.054*10⁻⁷ m
<u><em>The wavelength, λ, of a photon that has an energy of E = 3.92×10⁻¹⁹ J is 5.054*10⁻⁷ m</em></u>
Answer: Albedo
Explanation:
((Earth's normal albedo is about 0.3.)))
At the end of the day, around 30 percent of approaching sunlight based radiation is reflected go into space and 70 percent is consumed.
