Directions to Solve
Rearrange the following five sentences in proper sequence to form a meaningful paragraph, then answer the questions given below.
- A Study to this effects suggests that the average white-collar worker demonstrates only about 25% listening efficiency.
- However for trained and good listeners it is not unusual to use all the three approaches during a setting, thus improving listening efficiency.
- There are three approaches to listening: Listening for comprehension, Listening for empathy and Listening for evaluation.
- Although we spend nearly half of each communication interaction listening, we do not listen well.
- Each approach has a particular emphasis that may help us to receive and process informationin different settings.

ANS:C - Dynamic binding
No answer description is available. Let's discuss.

ANS:A -
- 0.000909 m
Correction should be positive since we measured longer than actual it was, mean that suppose we have seen on tape length is 150m while measurement but actual it was more than that of 150m, let say 151 m actual therefore to obtain this from 150 to 151m.
We need correction positive.
So, the right option will be C.
I think option A is correct; as the tape elongated due to extra pull applied, hence the measured length will be less than the actual.
The error is +ive but at the end of the question, "correction to be applied" has been asked. Which makes option A correct. The value of error is positive so we will deduct it from the final value, so the applied correction will be -0. 000909m.
30 m steel tape was standardized under 60 N pull at 65° F
It was suspended in 5 equal span during measurement. The mean temperature during measurement was 90° F and the pull exerted was 100 N. The area of the cross-section of the tape was 8 mm2. Find the true length of the tape, if, α = 6.3 * 10^6/F, E = 2 *105 N/mm2 and unit weight of steel = 78.6 kN/m3.
is the correction option.
Correction due to pull = (Pm-P0)*L/AE.
= (40-30)*30*100/1.5*0.1*2.2*10^6.
= +0.0909.
as pull you applied is more so the length measured will be less than true length and correction will be positive and error will be negative.

ANS:B - heated charcoal
Heated charcoal, also known as activated carbon or activated charcoal, is a highly porous form of carbon that has been processed to increase its surface area and adsorption capacity. Here's an explanation of heated charcoal:
-
Production: Charcoal is typically produced by heating organic materials, such as wood, coconut shells, or coal, in the absence of oxygen through a process called pyrolysis. This process drives off volatile compounds and leaves behind a carbon-rich material. Activated charcoal is then produced by further heating the charcoal to very high temperatures in the presence of a gas, such as steam or carbon dioxide, which creates pores and increases its surface area.
-
High Surface Area: The heating and activation process create a network of pores and a high surface area per unit volume. The surface area of activated charcoal can range from hundreds to thousands of square meters per gram, providing a large surface for adsorption.
-
Adsorption Properties: The porous structure of activated charcoal allows it to adsorb a wide range of substances onto its surface. It works through a process called adsorption, where molecules of gases, liquids, or dissolved substances adhere to the surface of the charcoal. This makes activated charcoal useful in various applications, including water purification, air filtration, and medical treatments.
-
Applications: Heated charcoal is widely used in various industries and applications:
- Water Treatment: Activated charcoal is used to remove impurities, odors, and contaminants from water. It can adsorb organic compounds, chlorine, heavy metals, and other pollutants.
- Air Purification: Activated charcoal filters are used in air purifiers and respirators to remove volatile organic compounds (VOCs), odors, and airborne contaminants.
- Medical Uses: Activated charcoal is used in medicine to treat poisoning and overdose cases. It can adsorb toxins and drugs in the digestive system, preventing them from being absorbed into the bloodstream.
- Industrial Processes: Activated charcoal is used in various industrial processes, such as gas purification, solvent recovery, and chemical filtration.
-
Regeneration: Activated charcoal can be regenerated and reused by heating it to high temperatures to desorb the adsorbed substances. This process restores its adsorption capacity, making it a cost-effective option for many applications.
In summary, heated charcoal, or activated carbon, is a versatile adsorbent with a high surface area and porous structure, making it effective for removing impurities and contaminants from water, air, and various industrial processes.

ANS:B - gear
Pumping of a corrosive liquid is generally preferred to be done by a gear pump, as it can be made of a variety of materials including plastics.
Explanation:
-
Gear Pumps:
- Gear pumps are a type of positive displacement pump that are well-suited for pumping corrosive liquids.
- They can be constructed from a variety of materials, including plastics and stainless steel, which are resistant to corrosion.
- They provide a steady flow and can handle viscous and corrosive liquids effectively.
-
Piston Pumps:
- Piston pumps are also a type of positive displacement pump but are typically more complex and can be more difficult to make from corrosion-resistant materials.
- They are better suited for high-pressure applications rather than handling corrosive fluids.
-
Positive Displacement Pumps:
- This term encompasses several types of pumps, including piston, gear, and diaphragm pumps. Among these, gear pumps are particularly noted for their suitability with corrosive liquids due to material options and design simplicity.
-
Sump Pumps:
- Sump pumps are typically used for removing water that has accumulated in a sump basin, commonly found in the basements of homes.
- They are not typically designed for handling corrosive liquids and are often made from materials that might not be resistant to corrosion.
Conclusion:
Given the need for handling corrosive liquids and the versatility in materials, gear pumps are generally preferred. They offer reliable performance, can be made from corrosion-resistant materials like plastics, and are effective in pumping corrosive fluids.
