In think is C or B in my opinion
Answer:
The hardness test is preferred to tensile test because it is simple, easy, and relatively nondestructive.
Tensile testing is a destructive test process that checks tensile strength, yield strength, and ductility of the metallic material.
Explanation:
Hardness test is a test carried out to check the resistance of a material to withstand permanent deformation such as indentation, wear, abrasion, scratch. It evaluates a material’s properties, such as strength, ductility, permanent deformation and wears resistance, and so helps you determine whether a material or material treatment is suitable for the purpose you require. This test is carried out by penetration of the material through another harder material.
Tensile testing is one of the most common mechanical testing techniques used to test the strength of material and also how much it can be stretched before it breaks. It is a destructive test process that provides information about the tensile strength, yield strength, and ductility of the metallic material.
Answer:
The answer to this question is Live Online Courses.
Explanation:
When we are enrolled in an online learning courses that is live so we can observe that there is synchronous communication in training.
The instructor is teaching at some other end using live broadcasting or other video broadcasting methods via internet and we are at the receiving end.

Answer:
int count;
for (int i = 1; i <= 100; i++){
count = 0;
for (int j = 1; j <=i; j++)
if (i%j==0) count ++;
if (count == 2) cout << i << " ";
}
