The bending of light about corners of an obstacle is called:

The power in an electrical circuit is give by \(\mathrm{P}=\mathrm{At}^{2}+\mathrm{Ct}\), where \(\mathrm{t}\) is the time. What will be the dimension \(\mathrm{A}\) and \(\mathrm{C}\) respectively are:

Three concurent forces F₁, F₂ and F₃ are in equilibrium. The magnitude of the forces F₁ and F₂ is 3 N and 4 N respectively and both are acting perpendicular to each other. Find the magnitude of the third force.

A circuit has a section \(A B\) as shown in the figure. The emf of the source equals \(E=10 V\), the capacitor capacitances are equal to \(C_{1}=1.0 \mu F\) and \(C_{2}=2.0 \mu F\) and the potential difference \(V_{A}-V_{B}=5.0 V\). Find the voltage across each capacitor.

Two resistors of \(10 \Omega\) and \(20 \Omega\) and an ideal inductor of \(10 H\) are connected to a \(2 V\) battery as shown in Fig. Key K is inserted at time \(t=0\). The initial \((t=0)\) and final \((t \rightarrow \infty)\) currents through the battery are:
