Yes that is correct. We know this because 4.00 x 10 4 Pa is constant. If you have 2.00×10−3m3 then you do the following: (2.00×10^−3)(4.00×10^<span> 4) = </span>8.00×10^−3. That is how you get your answer

Answer:
Acids break down fabrics and can cause burns if the acids are strong.
Explanation:
A protective apron or lab coat is important when working with acids because acids break down fabrics and can cause burns if the acids are strong.
- An acid is a substance that interacts with water to produce excess hydroxonium ions in an aqueous solution.
- A strong acid ionizes completely in solution.
- When they come in contact with a fabric, they break them down violently.
- So, if they come in contact with the skin, it causes a violent break down of body tissues.
- The apron acts a protective layer.

Distance travelled,
m
Since, the stone is released and it falls towards the sky, its initial velocity is zero
As per equation
, we will evaluate "t"
Substituting the given values in above equation, we get
![2.5 = 0 *t + 0.5 * 9.81 * t^2\\t^2 = \frac{2.5}{0.5*9.81}\\ t = \sqrt{0.5096} \\t = 0.714](https://tex.z-dn.net/?f=2.5%20%3D%200%20%2At%20%2B%200.5%20%2A%209.81%20%2A%20t%5E2%5C%5Ct%5E2%20%3D%20%5Cfrac%7B2.5%7D%7B0.5%2A9.81%7D%5C%5C%20t%20%3D%20%5Csqrt%7B0.5096%7D%20%5C%5Ct%20%3D%200.714)
