✓
Answer
| Property | Sol | Solution | Suspension |
| Nature | Heterogenous | Homogenous | Heterogenous |
| Particle size | $10^{-7}-10^{-5}cm$ | Less than 1nm | More than $100\ nm$ |
| Stability | Quite stable | Very stable | Unstable |
| Tyndall effect | yes | no | yes/no |
| Appearance | Generally clear | clear | opaque |
| visibility | Visible with an ultra microscope | Not visible | Visible with naked eye |
| Diffusion | Diffuses very slowly | Diffuses rapidly | Do not diffuse |
| Settling | Get settled in centrifugation | Do not settle | Settle on their own |
| Example | Milk, blood, smoke | Salt and sugar in water | Sand in water, dusty air |

An electron moving with a velocity of $5 \times 104 m s^{-1}$ enters into a uniform electric field and acquires a uniform acceleration of $104 m s^{–2}$ in the direction of its initial motion. Calculate the time in which the electron would acquire a velocity double of its initial velocity. How much distance the electron would cover in this time?
→A sound producing body is at considerable distance from a man. There can be four different media W, X, Y and Z between the sound producing body and the man. The medium X brings the sound to man most quickly whereas medium Z takes the maximum time. The time taken by medium W in bringing sound to man is less than that of X but more than that of Z. The medium Y, however, fails to bring the sound from the sound producing body to the man. Which medium could be the one:
