Answer:
Velocity component in x-direction 
.
Explanation:
v=3xy+
y
We know that for incompressible flow
So 
By integrate with respect to x,we will find
+C
So the velocity component in x-direction .
Answer:
A place where code is written.
Answer:
The metal Harvey should use for reflective coatings in telescope mirror is;
C. Aluminum
Explanation:
In a telescope, the mirror of the telescope is usually made of a temperature-resistant and strong glass, while the reflective coating of the mirrors is made usually from aluminum. A protective coating often composed of silicon dioxide is placed n the top of the reflective coating
Aluminum is used in a telescope, rather than the silver, which is the most reflective material, because silver requires special conditions to be able to work, and silver tarnishes when exposed to air containing sulfur, and silver is susceptible to corrode.
Answer:
B. Based on the allowable shear stress, but the allowable normal stress should always be checked to be sure it is not exceeded
Explanation:
Shear stress is analyzed to determine the shear forces along the lenght of the beam. This is represented in a shear force diagram. The beam cross sectional design is determined in such a way as to minimize the shear stress. Allowable normal stress should always be checked in a structure if failure is to be prevented.
