The Twelve Tables (aka Law of the Twelve Tables) was a set of laws inscribed on 12 bronze tablets created in ancient Rome in 451 and 450 BCE. They were the beginning of a new approach to laws which were now passed by government and written down so that all citizens might be treated equally before them.Apr
Answer:
depends how perceptible a person is and if they are influenced easily
Explanation:
The pH of the substance is 3.3 which is acidic.
<h3>What is pH?</h3>
The pH of a substance or solution is referred to the degree of acidity or alkalinity of that substance. It is measured on a scale of 0 -14.
Given the concentration of hydrogen ions as 5. 0 × 10–4 moles per liter,we use the formulae
ph = –log[h+]
plugging in thge value of h+ as 5. 0 × 10–4 moles per liter we have:
pH = –log{5. 0 × 10–4 ]
pH=3.3

Answer: See below
Explanation:
For this question, we are given the volume, and we want to find the diameter. We have to work backwards to get our radius, then to find the diameter.
(Volume of cylinder)
(The π cancel out)
(Plug in h=8)
(Divide 8)
(Square root of 9 is 3)
Now that we have our radius, we can find our diameter.
(Equation for diameter)
(Plug in r=3)
(Multiply)
The magnitude of the force of the elevator floor on the person is; 807.13 N
<h3>What is the Magnitude of force? </h3>
We are given;
Weight; W = 0.7 KN
Acceleration; a = 1.5 m/s²
There are only two forces acting on the person: which are his weight W (downward) and the normal force N of the floor against the body (upward). Thus the equilibrium equation here is;
N - W = F
N - W = ma
Here, m is the mass of body, and its value is calculated as;
W = mg
0.7 = 9.81m
m = 0.7/9.81
m = 71.42 kg
Thus;
N - 0.7 = 71.42 * 1.5
N = 0.7 + (71.42 * 1.5)
N = 807.13 N
