An AC generator producing 10V(rms) at 200 rad/s is connected in series with a $50 \Omega$ resistor, a 400 mH inductor and a $200 \mu F$ capacitor. The rms voltage across the inductor is

A wire has resistance of $3.1 \,\Omega $ at $30^{\circ} \, C$ and $4.5\, \Omega $ at $100^{\circ} C$ . The temperature coefficient of resistance of the wire is

An object is thrown vertically upward with a speed of $30\, m/s$. The velocity of the object half-a-second before it reaches the maximum height is

An electron collides with a Hydrogen atom in its ground state and excites it to $n = 3$ state. The energy given to the Hydrogen atom in this inelastic collision (neglecting the recoil of Hydrogen atom) is

A current flows in a conductor from east to west. The direction of the magnetic field at a point above the conductor is ................

1 mole of $H_2$ and 2 moles of $I_2$ are taken initially in a 2 litre vessel. The number of moles of $H_2$ at equilibrium is 0.2. Then the number of moles of $I_2$ and HI at equilibrium is

The pH of a buffer containing equal molarconcentration of a weak base and its chloride ( $K_b$ for weak base = $2 \times 10^{-5}$, log 2 = 0.3) is

If \[ \frac{(2 - i)\,x + (1 + i)}{2 + i} \;+\; \frac{(1 - 2i)\,y + (1 - i)}{1 + 2i} \;=\; 1 - 2i, \quad\text{then}\quad 2x + 4y =\;? \]
