Answer:
The answer is below
Explanation:
Newton's second law of motion states that the force applied to an object is directly proportional to the rate of change of momentum with respect to time, going in the same direction as the force.
Let F = force, m = mass of object, v = velocity of object, mv = momentum.
F = d/dt(mv) = m(dv / dt) = ma; a = acceleration.
Let us assume that the object starts from rest to 5 m/s within 1 seconds, hence:
F = m(dv / dt)
200 N = m[(5 m/s - 0 m/s) / (1 s)]
200 = 5m
m = 40 kg
Answer:
Explained below.
Explanation:
What has changed in the atmosphere is that oxidation has occurred where an oxidizing chemical specie has reacted with an oxygen containing compound.
Now these chemicals when they react with rain and fall on rocks react with the rocks to weaken them in a process known as chemical weathering.
Now when this weathering from the oxidizing chemicals from the rain react with rocks that contain iron, it leads to the rock having an appearance of rust.
Answer:
- Only the methyl ester of aspartame is sweet. True
- Amide bonds can be hydrolyzed under only acidic conditions. False
- The zwitterionic form of the amide bond is the most favored resonance form. True
- The phosphoric acid in soda hydrolyses the aspartame ester making it sweet. False
Explanation:
-
Aspartame is obtained by combining phenylalanine and aspartic acid. Its main impurity is dicetopiperazine, which does not possess sweetening properties.
- Amide bonds can be hydrolyzed both under basic and acidic conditions.
- The zwitterionic form of the amide bond is the most favored resonance form. A zwitterion is an electrically neutral chemical compound, but it has formal positive and negative charges on different atoms, presenting high stability
- Phosphoric acid creates an acidic medium that improves the absorption of carbon dioxide, reducing the pressure generated by carbon dioxide and thus allowing bottleneck. Phosphoric acid has a bitter taste that is offset by the addition of sugar
