An electromagnetic wave in a vacuum traveling in the x direction generated by a variable source initially has a wavelength λ of 265 μm and a maximum electric field emax in the y direction of 1.50×10−3 v/m . if the period of the wave is then increased by a factor of 2.30, what is the equation of the resulting magnetic field component of the wave

gas and liquid

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
