If the train stops then the math is gonna be c4
Answer:
D=1.0x10^-5 m^2/s
Explanation:
the data given by the exercise are as follows:
T=308 K
d=1 cm
PA=0.195 atm
pL=0.85 g/cm^3
The expression for binary gas-phase diffusion coefficient is equal to:
substituting the values in the diffusion equation:
from Appendix J-1 from Welty:
298 K, D=9.62x10^-5 m^2/s
At 308 K, we have the following:
Answer:
Both Technician A and Technician B are correct
Explanation:
Air tools and electric tools are both power tools as they are used to make work easier. Air tools generally use an air compressor that powers the motor of the tool making it possible to use it while electric tools as the name implies are powered by an electric source which in this case is batteries. An example of an air tool is the nail gun which can be used by furniture makers to drive nails and they are often louder than electric tools because of vibrations caused by the compressor making it necessary to use ear protection when using the tool for ear safety.
Technician B is also correct because it is always advisable to use impact sockets while using impact guns due to the ability of the impact sockets to withstand the force caused by operating impact guns and make work neater when nuts and bolts are being loosened or tightened.
