Answer:
a)We know that acceleration a=dv/dt
So dv/dt=kt^2
dv=kt^2dt
Integrating we get
v(t)=kt^3/3+C
Puttin t=0
-8=C
Putting t=2
8=8k/3-8
k=48/8
k=6
Answer:
what is wrong with it and what is the question
Explanation:
Answer:
Both
Explanation:
Because of water, fuel does not burn completely. This brings about water fumes that are white in color and looks like white smoke. If engine is cold and water is heating, it leads to steam formation like water vapor. The white times are because of not firing properly in the heated engine. Technician A is right.
Blue fine is caused by this scoring. It is also caused by dirty oil. Technician b is right too
Answer: (a) 1.11 nm/mm
Explanation:
Monochromator is a device which is used to transmits a delectable band of wavelengths of light wavelengths available at the input.
Assuming focal length monochromator equipped with a 1200-groove/mm grating
The formula for the first-order reciprocal linear dispersion is
where F is the focal length and n belongs to order of the first spectra.
Make sure you have used the conversion factors correctly as it will have a major impact on the calculation of the answer.
