Answer:
Racking is the term used for when buildings tilt as their structural components are forced out of plumb. This is most commonly caused by wind forces exerting horizontal pressure, but it can also be caused by seismic stress, thermal expansion or contraction, and so on.
Explanation:
Answer:Antifreeze/coolant
Explanation: keeps your engine cool in warm weather and keeps it from freezing up in the winter. A 50-50 mix of full strength coolant and water generally protects to around -30 degrees Fahrenheit. Make sure you check with the supplier or your owner's manual for the correct formulation
Answer:
1.693242
Explanation:
The colors in the Light emitting diodes have been identified by wavelength which is measured in nano-meters. Wavelength is a function of LED chip material. The LED diode which has a = 632 then A1 will be 1.63242, this is calculated by 1 / 632. Wavelength are important for human eye sensitivity. The colors emitted from the LED will depend on the semiconductor material.
Answer:

Explanation:
The first thing we will do is convert the units. Miles per hour to meters per second.


Performing the operations

Now, we will use the acceleration formula

Where v = speed and t = time
Substituting the values of 

Answer:
=0.60
Explanation:
Given :Take
=1.4 for air

=r ⇒ r=16
As we know that

So 
=909.42K
Now find the cut off ration 



So efficiency of diesel engine

Now by putting the all values

So
=0.60
So the efficiency of diesel engine=0.60
