Since the sine wave is an alternating wave it randomly changes its position along with the time so when it radiates or starts flowing it shows the tendency of heating and since we measure the sine wave in RMS it corresponds to the heat value of sine wave.

The RMS Voltage value is not a measure for a sine wave's heating effect. For that is the formula where is included the Current RMS Irms, the voltage Vrms and the time t. For this question, the right answer is "false".

The RMS voltage defines the equivalent heating effect that would apply. It is therefore equivalent to the DC voltage using the same resistance. This means all the DC formula will work in simple resistive circuits.

When we measure the power of any electric network then we use formula Vrms*Irms, so Vrms value is used for heating effect.

May be because p=I^2* are which is heat and depend upon temperature so same with RMS.
