Answer:
<h2>18 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 2 × 9
We have the final answer as
<h3>18 kg.m/s</h3>
Hope this helps you
The salivary amylase did not perform well if the pH becomes lower because it needs neutral pH for performing its functions.
<h3>Effect of pH on the enzyme</h3>
We can say that the salivary amylase did not perform their function very well within the stomach due to unfavourable environment such as lower pH. Due to lower pH, the enzyme structure is damaged so unable to perform its function so we can conclude that the salivary amylase did not perform well if the pH becomes lower.

<span>To find: Sample error in percent
Solution:
Formula:
((Experimental value-theoretical value)/theoretical value)*100
where, theoretical value = 100°c
and, experimental value = 102°c (sample 1) 99.2°c (sample 2)
Sample error (in percentage) when boiling level was 102°c = ((102°c-100°c)/100°c)*100 = 2%
Sample error (in percentage) when boiling level was 99.2°c = ((99.2°c-100°c)/100°c)*100 = -0.8%</span>
They are made up of chains of Hydrogen and c) Carbon
