Answer:
5 km North
Explanation:
Displacement refers to the distance covered in a specific direction.
In this case,
Distance covered due north = 8 km
Distance covered due south = 3 km
Therefore;
If we take the distance towards north to be +8 km
The distance towards south to be - 3 km
Then;
Displacement = +8km + (-3km)
= + 5km
= 5 km North
Therefore;
The displacement is 5km towards North.
Answer:
This ammonium laurel sulfates anion consists of a nonpolar hydrocarbon chain and a polar sulfate end group. It means it has a hydrophilic head and hydrophobic tail. There are ammonium ions, sulfate, and fatty acids present.
Lauryl sulfate has lauric acid attach to sulfate ions with carbon-sulfur bond, the fatty acid formed by the covalent bonds between C-C attached to hydrogens. Sulfur also bound to oxygen by covalent bonds. Nitrogen is surrounded by the four hydrogen atoms in the hydrophilic head.
They are both classified as stimulants.
It takes <u><em>about a month</em></u> for the Moon to complete one revolution around the earth. It is much longer than 60 hours and much shorter than 365 days. <u><em>So the correct answer is C. 29.5 days. I think you made a typo, because the correct answer is 29.5 days not years.</em></u>
