Answer:
After jumping to the higher energy level also called the excited state the excited electron would be in a less stable position, so it would quickly emit a photon to relax back to a lower, more stable energy level.
Answer:
This process is considered as a cycle because it continues and dosent stops. This process includes the evaporation of watet from earth surface due to heat.this water is converted in to water vapours. After reaching clouds it condences back. When the clouds become heavy with watef it falls back on earth as rain.and the process repeats.

Answer:
The correct answer is option B, that is, visible light.
Explanation:
The Sun is a prime source of ultraviolet rays. Although the Sun discharges all of the distinct types of electromagnetic radiation, 99 percent of its rays are in the form of ultraviolet rays, visible light, and infrared rays. The Sun emits radiation all through the electromagnetic spectrum, that is, from extremely high-energy X-rays to ultra-lengthy wavelength radio waves, and everything that comes in between. However, the peak of the emission takes place in the visible part of the spectrum.
After a radioactive atom decays, it is the same element that it was before with no measurable change in mass. the decay that is present is gamma decay because gamma decay has photons which has no mass unlike alpha and beta decay.

56 Explain why the total thermal energy of a sample containing 22.2 grams of NaNO3 dissolved in 200. grams of water at 20.°C is greater than the total thermal energy of a sample containing 11.1 grams of NaNO3 dissolved in 100. grams of water at 20.°C. [1]
57 Compare the boiling point of a NaNO3 solution at standard pressure to the boiling point of water at standard pressure. [1]
