The ammonium salt of acetic acid is the reaction product of acetic acid and ethylamine at room temperature
<h3 /><h3>What is acetic acid ?</h3>
Acetic acid is a monofunctional carboxylic acid containing two carbon atoms. It acts as a protein solvent, food acidity regulator, antibacterial food preservative. It is a conjugate acid of an acetate.
Acetic acid is used in the production of acetic anhydride, cellulose acetate, vinyl acetate monomer, acetic ester, chloroacetic acid, plastics, dyes, insecticides, photographic chemicals, and rubber. Other commercial uses include the production of vitamins, antibiotics, hormones, organic chemicals, and as a food additive. Typical concentrations of acetic acid found naturally in foods are 700 to 1200 milligrams/kg (mg/kg) in wine, up to 860 mg/kg in aged cheeses, and 2.8 mg/kg in aged cheeses. fresh orange juice.

The time elapsed since you stopped the stopwatch is 0.41 s.
<em>Your question is not complete, it seems to be missing the following information;</em>
"The velocity of the ant is 2 m/s"
The given parameters;
- velocity of the ant, v = 2 m/s
- change in position of the ant, Δx = 0.81 m
- time when the ant was noticed, = t₂
Velocity is defined as the change in displacement per change in time of motion of an object.
![v = \frac{\Delta x}{\Delta t} = \frac{\Delta x}{t_2 - t_1} \\\\t_2 -t_1 = \frac{\Delta x}{v} \\\\t_2 - 4 = \frac{0.81}{2} \\\\t_2 - 4 = 0.405\\\\t_2 = 0.405 + 4\\\\t_2 = 4.405 \approx 4.41 \ s](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7B%5CDelta%20x%7D%7B%5CDelta%20t%7D%20%3D%20%5Cfrac%7B%5CDelta%20x%7D%7Bt_2%20-%20t_1%7D%20%5C%5C%5C%5Ct_2%20-t_1%20%3D%20%5Cfrac%7B%5CDelta%20x%7D%7Bv%7D%20%5C%5C%5C%5Ct_2%20-%204%20%3D%20%5Cfrac%7B0.81%7D%7B2%7D%20%5C%5C%5C%5Ct_2%20-%204%20%3D%200.405%5C%5C%5C%5Ct_2%20%3D%200.405%20%2B%204%5C%5C%5C%5Ct_2%20%3D%204.405%20%5Capprox%204.41%20%5C%20s)
The time elapsed since you stopped the stopwatch is calculated as;
![t_{elapsed} = 4.41 \ s - 4\ s = 0.41 \ s](https://tex.z-dn.net/?f=t_%7Belapsed%7D%20%3D%204.41%20%5C%20s%20-%204%5C%20s%20%3D%200.41%20%5C%20s)
Thus, the time elapsed since you stopped the stopwatch is 0.41 s.

Ok so the equation for momentum is:
v=p/m
So you would do:
7800/1200=6.5
So the answer is:
6.5 m/s
Hope this helps :)
<span>the scientists want the probe to stop immediately and move at constant velocity.
HAPPY VALENTINES </span>
