Question

11. The ability of a material to bend without breaking
and to return to its original shape is
(a) flexibility (b) hardness
(c) tensile strength (d) conductivity.
12. The strength of a material to withstand a weight
without breaking is
(a) tensile strength (b) flexibility
(c) hardness
(d) metallic strength.
​

Answer 1

Answer:

1. flexibility
2. strength

Answer 2

11.The ability of a material to bend without breaking and to return to its original shape is called Flexibility.

Explanation:

Flexibility is defined as the ability to change, to bend, or to persuade.

12.The strength of a material to withstand a weight without breaking is called Tensile strength.

Explanation:

Tensile strength is a maximum load that a material can support without fracture when being stretched, divided by the original cross-sectional area of the material.

Hence,

11. option(a) flexibility is correct

12.option(a) Tensile strength is correct.
