P=V^2/R
So,R1 =220×220/100
R1=484ohm
R2=110×110/60
R2=201.67ohm
R1/R2=484/201.67
=2.39
So,R1 =220×220/100
R1=484ohm
R2=110×110/60
R2=201.67ohm
R1/R2=484/201.67
=2.39

wavelength=speed/frequency. So,wavelength=3×10^8/200×10^6 wavelenght = 1.5m
thanks ji ap kanha se hai
thanks again
radio radio waves of Speed 3 into 10 to the power 8 m per second are reflected of the moon and received back on the earth the time elapsed between the sending of the signal and receiving its back on the earth surface is 2.5 second what is the distance of the moon from the Earth
please kar de answer hai 3.75*100^8
apne questions me dal do
I will
