Q1: Mesh indicates the number of holes per

ANS:B - linear inch

Mesh indicates the number of holes per linear inch. Here’s a brief explanation:

• Mesh: Refers to the number of openings (or holes) per linear inch in a screening or filtering material, such as a wire mesh or a sieve.
• Square Inch: This measurement indicates that the count of holes is considered in square inches

A linear inch is a unit of measurement that refers to the distance of one inch along a straight line. It is used to quantify length in a single dimension without regard to width or depth, unlike measurements that consider square inches. Here's a breakdown of what a linear inch represents and how it differs from other measurements:

1. Linear Inch Definition:
   • A linear inch simply measures the distance of one inch in a straight line.
   • It is commonly used to specify lengths of objects or distances along a straight path.
2. Application:
   • Linear inches are used in various contexts where length is the primary consideration, such as measuring the length of a piece of fabric, the width of a board, or the diameter of cylindrical objects like pipes or wires.
   • In industrial and manufacturing settings, linear inches are often used to describe dimensions that are linear or one-dimensional.
3. Comparison with Square Inch:
   • A square inch, on the other hand, measures an area that is one inch by one inch, or the equivalent area of a shape with sides of one inch each.
   • It considers both length and width, providing a measure of two-dimensional space rather than just length.

In summary, a linear inch is a straightforward measure of length in one dimension, typically used when describing lengths along a straight line or the linear extent of an object or material.
