What is the difference between a photo diode and a solar cell?

State the characteristics of circular motion.

Compare the amount of work done in blowing two soap bubbles of radii in the ratio \(4: 5\).

What should be tension applied to a wire of length \(1 m\) and mass \(10 gram\), if it has to vibrate with fundamental frequency of \(50 Hz\) ?

In circular motion, assuming \(\vec{v}=\vec{\omega} \times \vec{r}, 01\), olbtain an expression for the resultant acceleration of a particle in terms of tangential and radial component.

Two capacitors each of capacity 2 μF are connected in parallel. This system is connected in series with the third capacitor of 12μF capacity. Find the equivalent capacity of the system.

Explain why centrifugal force is called a pseudo force.
