C. a(iii),b(ii),c(i)

D. a(ii),b(iii),c(i)

Answer : Option C
Explaination / Solution:

Intermediaries refers to people between the tiller and the state. they should be abolished as they bring stagnation in the Indian agricultural sector. The tenancy reforms laws provide the provisions for registration of tenants, or giving ownership rights to the former tenants to bring them directly under the state. Consolidation of land holdings refers to bringing together all plots of land into one block.

Q2. Among desert plants, which of the following will become a limiting for primary production

A. light

B. water

C. chlorophyll

D. temperature

Answer : Option B
Explaination / Solution:

Primary productivity is of plants depends upon availability of water, sunlight, chlorophyll, carbon dioxide etc. but in desert plants water is the main limiting factor as very less amount of water is available to plants in deserts.

Q6. Figure shows the position-time graph of a particle of mass 4 kg. What is the impulse at t = 0 and t = 4 s ? (Consider one-dimensional motion only)

A. 2 kg m

s^{- 1}

at t=0 and -2 kg m

s^{- 1}

at t = 4 s

B. 5 kg m

s^{- 1}

at t=0 and -3 kg m

s^{- 1}

at t = 4 s

C. 4 kg m

s^{- 1}

at t=0 and -4 kg m

s^{- 1}

at t = 4 s

D. 3 kg m

s^{- 1}

at t=0 and -3 kg m

s^{- 1}

at t = 4 s

Answer : Option D
Explaination / Solution:

Initial velocity $u = 0$ , between t= 0s and t=4s, the particle has a constant velocity,

therefore slope of OA is $v = \frac{3}{4} m / s$

At t= 0,Impulse=Change in momentum

= $m (v - u) = 4 (\frac{3}{4} - 0) = 3 k g m / s$

At t= 4s, initial velocity is 3/4 m/s,

So, the Impulse = $m (v - u) = 4 (0 - \frac{3}{4}) = - 3 k g m / s$

Q7. In the figure, when an ideal voltmeter is connected across 4000 ohm resistance, it reads 30 volts. If the voltmeter is connected across 3000 ohms resistance. It will read

A. 35 volt

B. 22.5 volt

C. 20 volt

D. 40 volt

Answer : Option B
Explaination / Solution:

An ideal voltmeter does not draw any current. Therefore the resistances 4000 Ω and 3000 Ω are in series. The current in the circuit

$\begin{array}{l} I = \frac{V_{4000}}{4000} = \frac{30}{4000} A \end{array}$

The potential difference across the 3000 Ω resistor
