Answer:
194 V/m
Explanation:
In order to find electric field, we can use the formula of power density
i.e Pd = E^2 / Z
where:
Pd = power density in W/m^2
E = electric field strength in V/m
Z = impedance of free space = 120 * π
E = sqrt(Pd * Z)
-----> re-arranging it for E
before solving, convert Pd unit into W/m^2
Pd= 5mW/cm^2 = 50 W/m^2
Solving for E:
E= sqrt(50 * 120 * π)
E = 137.3 V/m
the above value is RMS value
In order to find the peak amplitude of the oscillating field will therefore be 137.3 * sqrt(2) = 194 V/m

Answer:
Potential energy 
Explanation:
Given data
Weight of the person = 1000 N
Mass of the person = 
Speed = 6.26 
Kinetic energy is given by
Put the values in above formula we get
When the person reach top point then at this point the velocity is zero & kinetic energy at top point is equals to the potential energy.
Therefore potential energy
