2. Which of the following law is not important for ideal gas?

3. Which pair of aqueous solutions produce a yellow precipitate upon mixing?

4. The capacitance of a parallel plate capacitor increases from $5 \mu \mathrm{F}$ to $60 \mu \mathrm{F}$ when a dielectric is filled between the plates. The dielectric constant of the dielectric is-

5. The length of a runway is $100 \mathrm{~m}$. An acro-plane requires a velocity of $216 \mathrm{~km} / \mathrm{hr}$ to take off. If the acceleration of the aero-plane is $15 \mathrm{~m} / \mathrm{sec}^{2}$, will it be possible for the acro-plane to take off from this runway? What should be the minimum length of the runway to take off?
