Answer: 58.643 cm^3
Explanation:
Volume of a cone = (1/3) * π * r^2 * h
Half of the diameter is the radius, so r = 2 and h = 14.
Plug in: V = (1/3) * π * 2^2 * 14 = 58.643 cm^3 :)
Answer:
B. databases of periodicals
Explanation:
Databases include the citations of articles in magazines, journals and newspapers. A periodical is a magazine or newspaper published at regular intervals. So if she's looking for news articles about this earthquake then she should most likely search databases or periodicals.
Answer:
answer is quantitative .
Explanation:
Quantitative observations are made with instruments such as rulers, balances, graduated cylinders, beakers, and thermometers. These results are measurable.
Bromine has stronger inter molecular force than Fluorine.
<h3> Inter molecular forces and relationship with physical states of matter</h3>
The intermolecular forces of a substance tells the physical state of that substance , We can therefore say that the Solid, liquid and gas states of substances depends on the intermolecular forces surrounding them.
- For solids,the inte molecular forces will be so strong as they draw the molecules together giving them a compact structure.
- For liquids, the the inter molecular forces will be just strong enough to keep the molecules together in a confined space.
- For gases, the the inter molecular forces are weakest as the molecules move about.
We can then conclude that At stp, fluorine is a gas and bromine is a liquid because, compared to fluorine, bromine has a stronger intermoleclar force.

Stare at them and give them the look
