Answer:
A rivet is a mechanical fastener composed of a head on one end and a cylindrical stem on another (called the tail) which has the appearance of a metal pin.
When installed the rivet is either drilled, placed or punched into a hole, afterwards the tail is then deformed, holding the rivet in place. When finished the tail has the appearance of a dumbbell shape completing the riveted joint.

i have no clue brother i just came here for points
Explanation:
Answer:
Temperature distribution is
Heat flux=q
Heat rate=q A
Explanation:
We know that for no heat generation and at steady state
a and are the constant.
Given that heat flux=q
We know that heat flux given as
From above we can say that
Alos given that when x= L temperature is T(L)=T
So temperature T(x)
So temperature distribution is
Heat flux=q
Heat rate=q A (where A is the cross sectional area of wall)
Answer:
B) P1 would increase to maintain the flow rate ( correct )
C) The resistance would increase (correct )
Explanation:
flow rate = 10 liters per minute
Driving pressure (p1) = 20 cm H20
Fixed downstream pressure (p2) = 5 cm H20
The correct statements when we pinch the Lumen in the middle of the tube would be : P1 would increase to maintain the flow rate and The resistance would increase.this is because when we pinch the Lumen we reduce its diameter and the reduction of its Diameter will result to increased resistance against the flow and resistance of flow is directly proportional to pressure hence P1 would increase as well
The wrong statement would be : The flow would decrease
