Explanation:
Given that,
Magnitude of electric field in +x direction, E = 4.9 V/m
Part A :
The relation between electric and magnetic field is given by :
c is the speed of light
So, the magnetic field of the wave at this same point in space and instant in time is .\
Part B :
The direction of electric and magnetic field is same i.e. +x direction.
Hence, this is the required solution.
Yes because something that has been electrically charged can make other things move without touching them ( this is called force without contact)
Hoped this helped :)
Increase 4 times
Because velocity after increase is doubled to initial velotial. And velocity in the kinetic energy is squared, so the car’s kinetic energy after increase velocity equal 4 times the initial car’s kinetic energy
