One, two, and three i think
Answer:
a > 3 mm
so that critical flow is subject to detection
Explanation:
plane strain fracture toughness = 98.9 MPa root m
yield strength = 860 MPa
flaw detection apparatus = 3.0 mm
Y = 1
solution
we know critical stress formula that is
critical stress 
.............................1
here K is design stress plane strain fracture toughness and a is length of surface creak
so here length of surface creak will be
length of surface creak a = 
put here value
a = 
a = 0.0168 m = 16.8 mm = 0.66 in
so
a > 3 mm
so that critical flow is subject to detection

Answer:
d) social clock.
Explanation:
<em>The social clock </em><em>is defined as a concept or phenomena that tend to explore or figure-out different timetable that is being determined via social structure or culture that is responsible for describing a proper time related to a few specific events, for example, social status, graduation, marriage, and employment, etc. The concept of the social clock was first introduced by a psychologist named Bernice Neugarten during 1965.</em>
