The correct answer is 1000 Kg/M³
Density of water =1-g/cm3.
We know 1- g= 10^-³ Kg
cm³ =(10^-2)³= 10^-6
Substituting we get
Density of water
= 1 x (1x10^-³)/10^-6 Kg/M³
= 1x10^3 = 1000 Kg/M³
<h3>
what is density?</h3>
Density is the mass of a material substance per unit volume. Density is defined as d = M/V, where d represents density, M is mass, and V is volume. Density is generally measured in grammes per cubic centimetre. Water, for example, has a density of 1 gramme per cubic centimetre, but Earth has a density of 5.51 grammes per cubic centimetre. Density is sometimes measured in kilos per cubic metre (in metre-kilogram-second or SI units). The density of air, for example, is 1.2 kilogrammes per cubic metre. Textbooks and handbooks list the densities of common solids, liquids, and gases.

Answer=c
Atoms dont "lose" or "gain" protons, if they did, they'd be completely different elements. So basically, anything with 13 protons is a form of Aluminum.
I believe there are 3 significant figures B.
Answer:
C. All parts of Earth experience periods of daylight and darkness.
Explanation:
Not all parts of earth experience the same temperatures. For example, Alaska vs. Florida. Alaska is always freezing cold and Florida is generally always warm.
Not all parts of Earth experience extreme temperature changes either. For example, Florida doesn't experience extreme colds and Alaska doesn't experience extreme warmth.
Not all parts of Earth Experience the same amount of day and night. There are month long periods where Alaska doesn't see the sun, and it is pitch black, and dark. Florida experiences a decent amount of daylight. etc.
I used the same states for example throughout my answer to try to not confuse people. I hope my answer helped!
