The exciter provides fully coherent receiver local oscillator signals at radar frequency band as well as requisite, auxiliary high frequency clock signals. The exciter function is divided into an internal frequency synthesizer and an upconverter.
Hope this helps :)))
Answer:
power = 49.95 W
and it is self locking screw
Explanation:
given data
weight W = 100 kg = 1000 N
diameter d = 20mm
pitch p = 2mm
friction coefficient of steel f = 0.1
Gravity constant is g = 10 N/kg
solution
we know T is
T = w tan(α + φ ) 
...................1
here dm is = do - 0.5 P
dm = 20 - 1
dm = 19 mm
and
tan(α) = 
...............2
here lead L = n × p
so tan(α) = 
α = 3.83°
and
f = 0.1
so tanφ = 0.1
so that φ = 5.71°
and now we will put all value in equation 1 we get
T = 1000 × tan(3.83 + 5.71 ) 
T = 1.59 Nm
so
power = 
.................3
put here value
power = 
power = 49.95 W
and
as φ > α
so it is self locking screw

Answer:
True
Explanation:
To carry out a research in order to that it should yield the desirable result, a researcher must be very clear about his objective for the research.
The researcher must be very much clear about all the do's and don'ts and all the where, why, what sort of thing, i.e., the researcher must be clear about his/her intentions of carrying out the research, and what research is being carried out by him/her.
The one doing the research must be clear about the implications of the research.
Unless all these things are not clear at the researcher's end the research will not give the desired results.
