What is the maximum electric field strength (in kV/m) in an electromagnetic wave that has a maximum magnetic field strength of 5.90 x 10-4 T (about 10O times the Earth's)? kV/m

What is the maximum strength of the E-field in an electromagnetic wave that has a maximum B-field strength of 6.66 × 10^−6 ?.

A traveling electromagnetic wave in a vacuum has an electric field amplitude of 91.5 V/m. Calculate the intensity ? of this wave. Then, determine the amount of energy ? that flows through area of 0.0203 m2 over an interval of 15.7 s, assuming that the area is perpendicular to the direction of wave propagation.

Electromagnetic radiation from the sun reaches the earth at a rate 1370W/m^2. The radius of the sun is 6.96x10^8m and the distance from the center of the sun to earth is 1.5x10^11. Assume solar radiation reaches sun as single wave.  A) what is the electric field amplitude of solar radiation when it reaches earth ?   b)what is total energy radiated by sun in 2.5 seconds  give answer in J   c) if we assume sun emits like a black oft with emissivity e=1 calculate the temperature on the surface of Sun in Celsius  Please show work
