Describe the role played by women in agricultural production. |
|
Answer» (a)Women played an important role in agricultural production. They worked shoulder to shoulder with men in the fields. The men tilled and ploughed the lands whilethe women sowed, weeded and threshed the harvest. Agricultural production at the time was carried out with the labour and resources of the entire. (b) The women performed important tasks such as spinning yarn, kneading clay for pottery and embroidery. Thus, the peasant women who were skilled artisans worked not only in the fields but even went to their employer’s houses and even to the markets, if necessary. (c)Among the landed gentry class women had the right to inherit property. Women, including widows participated in the rural land market. Selling property which they had inherited especially in Punjab. (d)Both Hindu and Muslim women inherited zamindaris. They were free to sell or mortgage their zamidari rights. In eighteenth century, Bengal had many women- zamindars. In fact, the Rajshah zamindari which was one of the most famous of the time was headed by a woman. |

Flow cytometry, illustrated in the figure, is a technique used to sort cells by type. The cells are placed in a conducting saline solution which is then forced from a nozzle. The stream breaks up into small droplets, each containing one cell. A metal collar surrounds the stream right at the point where the droplets seprate from the stream. Charging the collar polarizes the conducting liquid, causing the droplets to become charged as they break off from the steam. A leser beam probes the solution just upstream from the charging collar, looking for the presence of certain types of cells. All droplets containing one particular type of cell are given the same charge by the charging collar. Droplets with other desired types of cells receive a different charge, and droplats with no desired cell receive no charge. The charged.

A hemispherical portion of radius R is removed from the bottom of a cylinder of radius R. The volume of the remaining cylinder is V and its mass is M. It is suspended by a string in a liquid of density ρ. It stays vertical inside the liquid. The upper surface of the cylinder is at a depth h below the liquid surface. The force on the bottom of the cylinder by the liquid is(a) Mg (b) Mg - Vρg(c) Mg + πR2 hρg(d) ρg(V + πR2 h) |
|
Answer» Correct Answer is:(d) ρg(V + πR2 h) Net upward buoyancy force on the cylinder = weight of liquid displaced by it = ρgV = (upward force on the bottom) – (downward force on the top) ∴ the force on the bottom is ρgV + (hρg)πR2 = ρg(V + πR2 h). |

The ends of a stretched wire of length L are fixed at x = 0 and x = L. In one experiment the displacement of the wire is y1 = A sin(πx/L) sin ωt and the energy is E1, and in another experiment the displacement is y2 = A sin(2πx/L) sin 2ωt and the energy is E2. Then(a) E2 = E1 (b) E2 = 2E1 (c) E2 = 4E1 (d) E2 = 16E1 |
|
Answer» Correct Answer is: (c) E2 = 4E1 A stationary wave has the equation of the form y = A sin kx sin ωt. Here, for y1, we have k1 = π/L, ω1 = ω. ∴ v1 = ω1/k1 = ωL/π. For y2, we have k2 = 2π/L, ω2 = 2ω. ∴ v2 = ω2/k2 = ωL/π = v1. Thus, the wave velocities are the same in both cases. Also, they have the same amplitude. The frequency for y2 is twice the frequency for y1. Now, B ∵ energy ∝ (frequency)2 , ∴ E2 = 4E1. |

Two identical small elastic conducting balls of mass m and radius r have charges of oppsite signs Q and -q. Inditially they are held in free space with their centres at separation `lgt 2r` and then released Their speeds v long after their collision is `v=sqrt((1)/(axxpiepsilon_(0)m){((Q+q)^(2))/(bxxr)-(Qq)/(l)})` (Ignore non-uniformity in charge distributuion when ball come close to each other, magnetic field produced by motion of charges and the gravitational interaction between them). Find `((6xxaxxbxx)/(48)`? (a and b are lowest possible integers) |
|
Answer» Correct Answer - 4 `v=sqrt((1)/(4piepsilon_(0)m){((Q+q)^(2))/(8r)-(Qq)/(1)}` kinetic energies of the ball can only change due to work done by interaction forces. The loss of energy due to redistribution of charge between the balls at time of contact will dissipate as heat and nothing to do with change in kinetic energy. Therefore, the balls gain kinetic energy at the expense of interaction energy before the collision, during collision they exchange their velcities and after the collision, they further gain kinetic energy at the expense of their interaction energy. |
