Question

Match the LIST-I with LIST-II

LIST-I	LIST-II
A. Electric Power B. Bullock Power C. Human Power D. Renewable Power	I. 0.1 hp II. Motor III. 0.5 hp IV. Non exhaustive

Choose the correct answer from the options given below:

• A. A-II, B-IV, C-III, D-IV
• B. A-II, B-III, C-IV, D-I
• C. A-III, B-I, C-II, D-IV
• D. A-II, B-III, C-I, D-IV

Hint:

Remember the standard farm power values: \[ \text{Human Power} \approx 0.1\,hp \] \[ \text{Bullock Power} \approx 0.5\,hp \] Also, renewable resources are always called non-exhaustive resources because nature continuously replenishes them.

Answer 1

The Correct Option is D

Concept: Agricultural power sources are broadly classified into animate and inanimate sources. Animate power includes human and animal power, whereas inanimate power includes electrical, mechanical, wind, solar and other renewable energy sources. Matching type questions in farm power engineering are solved by carefully understanding the characteristics, magnitude and application of each power source. The following important facts are useful:
• Electric power is commonly supplied through electric motors.
• Bullock power is approximately equal to \(0.5\) horsepower.
• Human power is approximately equal to \(0.1\) horsepower.
• Renewable energy resources are called non-exhaustive resources because they are naturally replenished. These standard values are widely used in agricultural engineering and farm machinery studies.

Step 1: Matching Electric Power. Electric power is generally utilized in farms through electrical machines and motors. Electric motors convert electrical energy into mechanical energy for operating irrigation pumps, threshers, grinders and other agricultural machinery. Therefore: \[ \text{Electric Power} \rightarrow \text{Motor} \] Hence, \[ A \rightarrow II \]

Step 2: Matching Bullock Power. Bullocks are traditional draught animals used for ploughing, transportation and field operations in agriculture. The average useful power developed by a pair of bullocks is approximately: \[ 0.5 \, \text{horsepower (hp)} \] Therefore: \[ \text{Bullock Power} \rightarrow 0.5 \, hp \] Hence, \[ B \rightarrow III \]

Step 3: Matching Human Power. Human beings can provide only limited mechanical power for agricultural operations. The average sustainable power developed by a human worker is approximately: \[ 0.1 \, hp \] Therefore: \[ \text{Human Power} \rightarrow 0.1 \, hp \] Hence, \[ C \rightarrow I \]

Step 4: Matching Renewable Power. Renewable energy sources such as solar energy, wind energy, biomass energy and hydropower are continuously replenished by nature. These sources are termed: \[ \text{Non-exhaustive resources} \] because they are not depleted permanently by usage. Therefore: \[ \text{Renewable Power} \rightarrow \text{Non exhaustive} \] Hence, \[ D \rightarrow IV \]

Step 5: Writing the final matching sequence. Combining all the correct matches obtained above: \[ A-II,\; B-III,\; C-I,\; D-IV \] This corresponds to: \[ \boxed{\text{Option (D)}} \] Verification Table: \[ \begin{array}{|c|c|} \hline \text{LIST-I} & \text{LIST-II} \hline A.\ \text{Electric Power} & II.\ \text{Motor} \hline B.\ \text{Bullock Power} & III.\ 0.5\,hp \hline C.\ \text{Human Power} & I.\ 0.1\,hp \hline D.\ \text{Renewable Power} & IV.\ \text{Non exhaustive} \hline \end{array} \] Thus, the correct answer is: \[ \boxed{A-II,\; B-III,\; C-I,\; D-IV} \]
