The answer is A. The vibration caused by the waves through the air eventually weaken, which is why sound diminishes easily over distance.
Answer:
I <em><u>THINK mechanical energy</u></em>
Answer:
because when you burn some wood you don't just get ash, you also get energies like thermal energy(heat), light and also some gaseous compound are produced (like CO2, SO2 etc) for the combustion reaction(a reaction where something is burnt in presence of O2). So the energy reserved in the wood are transformed into heat, light, other compounds and some turn into ash.
B) loses electrons and is oxidised
Its oxidation number is 0 in Co(s) and +2 in Co(C2H302)2(aq), hence it gets oxidised
Answer:
The products of hydrolysis of proteins, carbohydrates and fats and oils during digestion are <u>amino acids</u>, <u>simple sugars/monsaccharides</u> and <u>triglycerol and fatty acids</u> respectively.
Explanation:
- <em><u>Glycosidic links (ether bonds) </u></em>are hydrolyzed in carbohydrates to give <em><u>monosaccharides </u></em>(such as fructose and glucose)
- <em><u>Ester bonds</u></em> (functional groups) in triglycerides are hydrolyzed (acid hydrolysis) to form <em><u>glycerides and fatty acids</u></em>
- <u><em>Peptide bonds</em></u> in proteins are hydrolyzed to produce their constituent <em><u>free amino acids</u></em>.
N.B: Hydrolysis during digestion is usually catalysed by enzymatic action in the intestines.
