The negative mark is balanced by a positive mark on the set key scale while the jaws are closed.
It is common practice to shut the jaws or faces of the system before taking some reading to guarantee a zero reading. If not, please take care of the read. This read is referred to as "zero defect."
There are two forms of zero error:
zero-mistake positive; and
Non-null mistake.

Answer:
0.1336
Explanation:
The formula for pressure is force exerted by the object divided by area the object covers.
The marking off table has a mass of 500 kg. You can find its weight by applying the equation;
w= m* g where w is weight , m is mass and g is acceleration due to gravity
w= 500 * 9.81
w= 4905 N
Formula for pressure is;
P= F/A
3.5 *100000 N = 4905 / A
350000 N = 4905 /A
A= 4905/350000
A= 0.0140 m²
To get the internal diameter apply the formula;
A=πr² where A is area of a cylindrical shaped object, r is radius
0.0140 = π * r²
0.0140/π = r²
0.0044608 = r²
√0.0044608 = r
0.06678 m = r ------D = 2r
0.1336 = D

Explanation:
Here, we are concerned with stating the advantages and disadvantages of using a 6 tube passes instead of a 2 tube passes of the same diameter:
<u>Advantages</u>
* By using a 6 tube passes diameter, we are increasing the surface area of the heat transfer surface
* As a result of increasing the heat transfer surface area, the rate of heat transfer automatically increases too
Thus, from the above, we can conclude that the heat transfer rate of a 6 tube passes is higher than that of a 2 tube passes of the same diameter.
<u>Disadvantages</u>
* They are larger in size and in weight when compared to a 2 tube passes of the same diameter and therefore does not find use in applications where space conservation is quite necessary.
* They are more expensive than the 2 tube passes of the same diameter and thus are primarily undesirable in terms of manufacturing costs
