Answer: An engineer or a craftsperson
Explanation:
Welding symbols allow the engineer or draftsperson to communicate detailed information about the weld to the welder. In most cases, the welding symbol has an arrow, which points to the location on the drawing where a weld is required. The arrow is attached to a leader line that intersects with a horizontal reference line. The arrow and leader line point to the joint in question, while the weld symbol tells the welder what type of weld to do. If the weld symbol is below the reference line, the weld should be made on the same side as the arrow.
Answer:
While air is compressed in a piston cylinder there are following types of irreversibilities
1.Due to finite temperature difference heat transfer take place between cylinder and surrounding.
2.Due friction force between cylinder and piston .
3.Compression process is so fast due to this ,it leads in the irreversibility of system.
Answer:
The total hole mobility is 41.67 cm²/V s
Explanation:
Data given by the exercise:
hole mobility due to lattice scattering = ul = 50 cm²/V s
hole mobility due to ionized impurity = ui = 250 cm²/V s
The total mobility is equal:
Answer: MAP!!! it's always a good Idea to have a map nearby, cause you'll never know when you'll need it or like you said, lose reception
