Because it will always let you down
Answer:

Explanation:
The question is missing an image. I have added this as an attachment to my answer.
Given;
Q = total charge
R = radius of cylindrical shell
h = height of cylindrical shell
d = distance of point from the right side of the cylinder
Let the thickness of the cylindrical shell be
, and the charge
,
Now, using the formula for finding the electric field due to a ring at a chosen point:

where
= center of the ring to the point
= electrostatic constant
We integrate on both sides from the limits
to
in order to determine the electric field at the point 
= 
Metal would be a better conductor cause electricity can travel easier through it
Density = mass divided by volume so if you use that formula Liquid A turns out to be a higher density so it flows slower.
The volume in units of 6.03x10^3 in3
1ft = 12 inch
So to convert foot into inches we have to multiply by 12
The volume of container = 3.49ft^3
=3.49×12×12×12
= 6030.72 in^3
<h3>
What is the volume of a container?</h3>
The amount of space a container encloses, or how much room is inside of it, is measured by its volume. The volume of a box can be calculated using this straightforward formula: volume V = L × W × H for a box with height H, width W, and length L.
Many different units can be used, however because of the way this formula is written, the volume would have length to the third power dimensions. For instance, if the container's measurements are given in metres, the capacity of the box will be given in metres squared, or m3.
