Answer:
4 miles north
Explanation:
Initially Scott travels 5 miles north at this point his displacement is 5 miles toward north
then he goes 3 miles south. which makes his displacement 2 miles (5 - 3 = 2) towards north as north and south are opposite directions.
finally he travels 2 miles due north.so his final displacement is
2 miles + 2 miles = 4 miles towards north direction

Answer:
Contains DNA, Contains Ribosomes, Lacks a nucleus
Explanation:
Sodium bicarbonate (or baking soda) will cause both exothermic and endothermic reactions when added to water. It becomes either unstable or stable carbonic acid, which will eventually become CO2. The reaction would be exothermic is when H2CO3 (Carbonic Acid unstable) is formed and endothermic is when CO2 is.
Answer:
The log will float on the water because its density is lower than the liquid, so it will stay at the top due to Archimedes' principle.
