Answer:
HCI creates an acidic environment, which promotes the process of pepsin.
When that happens, pepsin is maximally active and works on a fully digestion of the presented protein.
On the other hand HCI prevents the activeness of the amylase, thereby only a small part of starch is digested.
Explanation:
The physiological significance of these effects are: salivary glands found in the mouth which has a neutral pH environment segregates amylase, meanwhile pepsinogen becomes pepsin thanks to the compatibility with this environment.
While pepsin is widely active at a lower pH inside the stomach, amylase activity, on the other hand decreases at lower pH environment.
By definition we have that the force for time is equal to the product of the mass for the change in speed.
We have then that
F * (delta t) = m * (delta v)
Clearing the mass
m = (F * (delta t)) / (delta v)
Substituting the values
m = ((3.00) * (4.00)) / (7.50-6.00) = 8
answer
The mass of the moving object is 8Kg
