I will try In sha Allah.
Thank you!I will try In sha Allah.
Don't thank me now.I haven't done anything yet.XDThank you!
Isn't the uplink the signal transmitted from earth? Which frequency is higher and why?the uplink frequency is a tiny fraction of signal transmitted from the earth...the satellite regenerates and amplifies it an transmits it to earth at a different frequency..
This allows it to effectively receive and re-transmit information without risk of overlap or mixed reception with the received signal
c)i) Ir/I= 4/225
yea ...i said the same....the satellite regenertes it back to earth as downlink after amplification ..Isn't the uplink the signal transmitted from earth? Which frequency is higher and why?
the formula is same u just have to take the reflection into account...
u knw Debrogleis wavelength ...every moving particle has a wavelength associated with it ...photons incident on the surface have a wavelength of 590nm.....View attachment 60306 Can someone explain me the b part
http://physics-ref.blogspot.com/2015/04/physics-9702-doubts-help-page-119.htmlSomeone please explain this part.
http://physics-ref.blogspot.com/2015/10/physics-9702-doubts-help-page-218.htmlIn part ii, don't we have to convert power into energy first??? And why are we subtracting the masses? We don't consider the overall total mass? And please explain 2 as well. SOMEONE View attachment 60323
Thanks a millionc)i) Ir/I= 4/225
then
c)ii) Intensity = I*e(-48*2*x).As the ultrasound will be attenuated going from the surface to the boundary and from the boundary to surface, so it moves twice the distance. Thats the intensity that comes at the barrier, 4/225 of that is reflected back. so
(4/225)*I*e(-48*2*x)=0.012*I
cancel I with I
ln (0.012/0.018) = -48*2*x
x=4.22x10^-3 m
=0.42cm
speed with force of magnetic field... You will use F=BeVSomeone help me in determining the relation of force with speed. Will we use F=mv^2/r or F=qvBView attachment 60321 View attachment 60321
Each photon contributes to the total power, so power =n * energy of photonhow is no of photons = power / energy of photon?
Its equal to current through main circuit or cell * Potential difference across cell.Is the power produced in a cell equal to the the total power in the circuit?
By p.d across cell you mean the terminal p.d right?Each photon contributes to the total power, so power =n * energy of photon
it also depends on rate so the question here matters. bc its not a rule u have to know
Its equal to current through main circuit or cell * Potential difference across cell.
No. Power lost through the cell is still power generated. The question will specify what it needs, really, so itll be obvious which to include/By p.d across cell you mean the terminal p.d right?
Thanks but I dont get this, somehow. :/
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
