ANS:E - Both I and II are implicit

Explanation: Since the policy is expected to work just because it turned out fruitful in another company, it is evident that the problem in both companies was similar and monetary incentives always motivate workers. So, both I and II are implicit.

ANS:A - The force of friction always acts in a direction opposite to that in which the body tends to move

 "The force of friction always acts in a direction opposite to that in which the body tends to move" is a fundamental principle of friction in physics. Friction is a force that opposes the relative motion or tendency of motion between two surfaces in contact. When an external force is applied to an object, attempting to move it across another surface, the force of friction acts to resist this motion. The frictional force arises due to the interactions between the molecules at the surfaces in contact. Consider a situation where a book is placed on a table. If you push the book to the right, intending to move it across the table, the force of friction between the book and the table acts in the opposite direction, i.e., to the left. This frictional force opposes the motion or tendency of motion of the book across the table. Similarly, if you try to slide a heavy box along the floor, the force of friction between the box and the floor acts in the direction opposite to the intended motion of the box. As you push the box forward, the frictional force opposes your push by acting backward. This principle holds true not only for objects sliding across surfaces but also for situations involving rolling or fluid friction. In each case, the force of friction acts to impede the motion or tendency of motion of the object. Therefore, the statement "The force of friction always acts in a direction opposite to that in which the body tends to move" encapsulates the nature of frictional forces and their role in resisting motion between surfaces in contact.

ANS:A - Parabola

A parabolic shape for the plot of filtrate volume versus time is typically associated with constant rate filtration, not constant pressure filtration. Here’s an explanation of constant rate filtration and why it forms a parabolic curve:

Constant Rate Filtration:

1. Definition:
   • In constant rate filtration, the rate at which filtrate (liquid) passes through the filter medium remains constant over time.
   • This constant rate is typically achieved by applying a constant pressure drop across the filter medium.
2. Filtration Process:
   • Initially, during the early stages of constant rate filtration, the filtrate volume increases rapidly with time.
   • As the filter cake (solid material accumulating on the filter medium) thickens, the rate of filtration gradually decreases.
   • This results in a parabolic relationship between filtrate volume and time, where the filtrate volume increases rapidly at first and then more gradually as filtration continues.
3. Shape of the Plot:
   • The parabolic curve indicates that the rate of filtration is decreasing over time as the filter cake builds up and resistance to flow increases.
   • Mathematically, the parabolic shape can be represented by the equation that describes how the filtrate volume accumulates over time under constant rate conditions.

Constant Pressure Filtration:

• In contrast to constant rate filtration, constant pressure filtration refers to a process where the pressure applied to the filtration system remains constant.
• Under constant pressure, the rate of filtration may vary initially but stabilizes over time as the filter cake develops and the resistance to flow reaches equilibrium.
• The plot of filtrate volume versus time in constant pressure filtration typically forms a straight line because the rate of filtration remains constant once equilibrium is reached under the constant pressure condition.
