Answer:
The best method is using the jacket
Explanation:
The A-B-C extinguisher is made out by a potasyum acetate that react to vegretables oils and that tyoy of extinguisher ar recommended by industrial kitchens and restaurants.
On the other way using a jacket is better because fire need oxygen to keep in combustion. And if we apply a big area of something that confined the fire and keep the oxygen out is better than use a A-B-C extinguisher.
Answer:
Density does not change when you divide the cube, due to the principle of mass conservation. The density given in this case by 3 
, will remain the same.
The only way for it to change, will be if you compressed the block, so now the same mass will be compressed in less volume, or you add heat to the system.
Explanation:
I think that the answer is yes. Because copper is a cunductor of DC and AC. However electritions are trying to avoid copper wiring because its a poor conductor.
So I guess you could goth ways but I say yes it could work.
Answer:
Possible options:
A. nA, nC, nB
B. nA, nB, nC
C. nC, nB, nA
D. nC, nA, nB
E. nB, nA, nC
Answer is D
Explanation:
When the light is refracted into liquid B it is bent away from the normal, so that nA > nB. When the light is refracted into liquid C it is bent toward the normal, so that nC > nA. Therefore, we conclude that nC > nA > nB
