According to the research, the correct option is a bar graph. It is the best way to show the lead levels in six contaminated water wells.
<h3>What is a bar graph?</h3>
It is a graph that is used to show the changes that the data have undergone by graphing the data in bars, representing the frequencies by means of columns (or bars), through their height in a Cartesian plane.
It is a way of summarizing a set of data by categories, allowing different values to be compared using bars of different sizes.
Therefore, we can conclude that according to the research, the correct option is a bar graph. It is the best way to show the lead levels in six contaminated water wells.

Answer:
60000J
Explanation:
Given parameters:
Mass of car = 1200kg
Speed = 10m/s
Unknown:
Kinetic energy = ?
Solution:
The kinetic energy is given as:
Kinetic energy = 
m v²
Now insert the parameters and solve;
m is the mass
v is the velocity
Kinetic energy = x 1200 x 10² = 60000J
That is a bond between carbon and chlorine, as in chloro methane:
H3C-cl
i hope i helped you❤
To determine the heat or energy needed for the process, we use the equation,
H = mcpdT
where m is the mass, cp is the specific heat and dT is the temperature difference.
H = (95.4g)(0.44 J/g°C)(32°C - 22°C)
= 419.76 J
Thus, the amount of heat that should be ABSORBED is approximately 419.76 J.
