Question

Given below are two statements:

Statement $I$: An $AC$ circuit undergoes electrical resonance if it contains either a capacitor or an inductor.

Statement $II$: An $AC$ circuit containing a pure capacitor or a pure inductor consumes high power due to its non-zero power factor.

In the light of above statements, choose the correct answer from the options given below

✓

Answer

For resonance, $\phi=0$, hence both inductor and capacitor must be present. Also power factor is zero for pure inductor or pure capacitor hence both the component consume zero average power.

A crew of scientists has built a new space station. The space station is shaped like a wheel of radius $R,$ with essentially all its mass $M$ at the rim. When the crew arrives, the station will be set rotating at a rate that causes an object at the rim to have radial acceleration $g,$ thereby simulating Earth's surface gravity. This is accomplished by two small rockets, each with thrust $T$ newtons, mounted on the station's rim. How long a time $t$ does one need to fire the rockets to achieve the desired condition?
