the graph shows the supply and demand curves for a certain product, which has a current selling price of $400. The laws of suppl
1 answer:
Answer: A: The current selling price matches the product's equilibrium price.
Explanation:
The graph is attached for a better analysis.
From the graph, we can see that the Equilibrium price is $400 while the equilibrium quantity supplied and Equilibrium quantity demanded is 4000.
Since the current selling price is $400 and the equilibrium price is $400 as well, then we can say that the current selling price matches the product's equilibrium price.
Therefore, the correct option is A.

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
