Explain whether the rms voltages are always the same for two alternating voltages of the same peak value and of the same frequency.

State whether the following statements are true or false : Two intersecting lines cannot both be parallel to the same line.

For any-AC wave the effective voltage is how much of the peak value?

In any ac circuit, is the applied instanteneous voltage equal to the algebraic sum of the instantneous voltages across the series elements of the circuit?Is the same true for rms value?

Will the rms speed of molecules of different gases at the same temperature be the same?

According to the kinetic theory of gases, the average kinetic energies of O_(2) and N_(2) molecules are the same at a particular temperature. State whether the rms velocities of the molecules of the two gases at a given temperature will be the same or not.

Two plants belongs to same species if they

What is the peak value of the voltage of a 220V ac line?
