flux will graph wwill be in phase with current in primary coil graph...........wats the cnfusion here?

but i don't understand the relation between them...can you elaborate it a bit more

One condition for a satellite to be in geostationary orbit is that the orbit of the satellite must lie in the plane containing the equator. Explain why this is necessary?

I'm not sure about this but here is what I think:

Geostationary orbiting satellites should be stationary in a certain part with respect to Earth. Meaning that if you look at a certain part in the sky you'll always find it there! A satellite in a Geostationary orbit rotates the Earth in one day. However, the Earth also rotates around the equator in one day. If the satellite were to stay at a point NOT on the equator, then as a result of the Earth rotating around itself, you'll lose track of the satellite....

AOA

wel the diagram of the circuit will be the same as in aplication booklet page 11 , topic relay and diodes

fig.1.16 there is some problem in the sysrem or else i can upload the picture as well


apart mY coceptds are not crYstl clear so May be wrong but I dont think so!

waalaikumassalam wr wb!

i need help with this too...

 

[uhannan]

i need physics a2 application booklet. the latest one. help?!

well yes I confirmed this the same diagram is to be made as I have stated is in the aplication booklet

 

[XPFMember]

well yes I confirmed this the same diagram is to be made as I have stated is in the aplication booklet

but is it like both of them will be earthed...? like same line...it looks kinda odd...
possible for u to upload?

We are taking the difference in heat loss at both power ratings!
