Answer:
Isotopes – caused by varying numbers of neutrons in an element – have many practical uses in our society. ... In geology and archaeology, radioactive isotopes are used to determine the age of a sample while hydrologists can use isotope signatures to distinguish between different groundwater types.
Explanation:
Google. It's a magical place.
Answer:
The solution becomes more concentrated
Explanation:
As the solvent evaporates, the solute remains intact. This implies that we have more of the solute than the solvent in the solution. So as the evaporation continues, the resulting solution becomes more concentrated as we now have more of the solute than the solvent.
Answer:
Decreasing order is as follows:
γ-rays > x-rays > red light > infrared > radio
Explanation:
Energy and wavelength are inversely related with each other.
In other words, energy decreases as the wavelength of electromagnetic radiation increases.
Order of wavelength for the given radiations are as follows:
Radio > infrared > red light > x-rays > γ-rays
So, order of the energy will be reverse.
γ-rays > x-rays > red light > infrared > radio
Do you relizes how many activities lead to global warming? When gas is burned in a car, it produces carbon dioxide (a green house gas). The carbon dioxide then floats up towards the atmosphere and becomes part of the atmosphere. This then causes the heat from the sun to get trapped, bouncing from the atmosphere to the earth. The sun will never stop producing heat which will only lead to the world getting hotter as each decade goes by.
Hope this helps you!
