Please answer quickly The angular frequency of waveform having a period of 1 msec is 2pi radians/sec.       True       False   Root mode square value of a signal is same as the effective value of a signal.  True  False   The magnetic field energy stored in between the plates of the capacitor is mathematically equal to the half of the product of its capacitance and the square of the voltage across the capacitor.  True  False

I have tried answering this problem and I've arrived at an answer of 1.287 or 1.29, but this answer is marked wrong. To anyone who is good at electromagnetics please help me and show me how this problem is done. Thank you.

The figure below shows an electric field line, at point A, draw the direction of the electric field vector A

This is a practice problem from the Engineering Electromagnetics course in my Electrical Engineering program. Could you please walk me through the steps of solving it so that I can solve more complicated ones in the future? Thank you for your assistance.

A parabolic reflector focuses electromagnetic waves into a beam as shown in the figure. The electromagnetic radiation is pulsed, with a pulse frequency of 16.0 GHz, and the duration of each pulse is t = 1.00 ns. The face of the reflector has a radius of 5.00 cm, and the average power during each pulse is 20.0 kW. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) (a) What is the wavelength (in cm) of these electromagnetic waves? cm (b) What is the total energy (in µJ) contained in each pulse? (c) Compute the average energy density (in mJ/m³) inside each pulse. mJ/m³ (d) Determine the amplitude of the electric field (in kV/m) and magnetic field (in µT) in these electromagnetic waves. Emax kV/m %3D B max HT (e) Assuming that this pulsed beam strikes an absorbing surface, compute the force (in uN) exerted on the surface during the 1.00 ns duration of each pulse. µN

Don't use ai to answer I will report you answer

Write this out clearly

The parallel-plate capacitor shown to the right is discharging so that the electric field between the plates decreases. Answer the questions below and explain your reasoning. The bulk of the credit will come from your explanation. What is the direction of the magnetic field at point P?
