Which factor allows polymerization, a process with negative entropy change ((Delta S < 0)), to be thermodynamically spontaneous?
💡 Explanation:The criterion for a spontaneous process is a negative change in Gibbs free energy ((Delta G < 0)), according to the equation (Delta G = Delta H - TDelta S). Polymerization is the linking of small monomers into a large polymer chain, which decreases the total number of free molecules, resulting in a negative entropy change ((Delta S < 0)). For the reaction to still be spontaneous ((Delta G < 0)), the enthalpy change ((Delta H)) must be highly negative (exothermic) to overcome the positive term of (-TDelta S), especially at lower temperatures where the spontaneity is often observed.

A 10 Omega resistor carries a 5 A current. What is the circuit’s voltage?
💡 Explanation:According to Ohm's Law, the voltage (V) across a resistor is the product of the current (I) and the resistance (R). The formula is $V = I times R$. Therefore, $V = 5 text{ A} times 10 Omega = 50 text{ Volts}$.

What is the dominant force driving the movement of lithospheric plates according to modern models of plate tectonics?
💡 Explanation:Modern understanding of plate tectonics suggests that 'Slab Pull' is the strongest force driving plate movement. This force is the result of the gravitational sinking of cold, dense oceanic lithosphere into the mantle at subduction zones (trenches), dragging the rest of the plate along behind it. 'Ridge Push' is a secondary force caused by gravity sliding the elevated, newly formed lithosphere away from the mid-ocean ridges. While mantle convection (Basal Traction/Drag) is the ultimate source of heat and is part of the system, it is generally considered a minor or resisting force compared to the gravitational forces of slab pull and ridge push.

Which agreement formalized the Line of Control (LoC) between India and Pakistan in 1972?
💡 Explanation:The Line of Control (LoC) is the military demarcation line separating the Indian and Pakistani-controlled parts of the former princely state of Jammu and Kashmir. It was formally established and recognized by the Simla Agreement, signed by the Prime Ministers of India and Pakistan in July 1972.

Which function fundamentally distinguishes TCP from UDP in network communication?
💡 Explanation:Transmission Control Protocol (TCP) is a connection-oriented protocol that ensures the reliable, sequential, and guaranteed delivery of data packets through mechanisms like sequencing and acknowledgments. User Datagram Protocol (UDP) is a connectionless protocol that offers faster, lower-overhead transmission but provides no guarantees of delivery or packet order. Thus, guaranteed delivery and ordered packets is the key distinguishing function.

Which economic model describes growing disparity between the rich and poor following a recession?
💡 Explanation:A K-shaped economy is a post-recession recovery pattern where the performance of different sectors or groups diverges significantly. Some segments (typically high-income earners and tech) recover quickly and continue to prosper (the upper arm of the K), while others (low-income earners and traditional industries) experience a continued slump (the lower arm), leading to entrenched inequality.

What is the immediate effect of a central bank selling government bonds on money supply and interest rates?
💡 Explanation:Selling government bonds on the open market is a contractionary monetary policy action (Open Market Sales). When the central bank sells bonds, commercial banks use their reserves to purchase them, which effectively removes money from the banking system, thus reducing the money supply. A decrease in the money supply (or reserves) increases the cost of borrowing for banks, leading to a rise in market interest rates.

What does the short-run Phillips Curve primarily illustrate in macroeconomics?
💡 Explanation:The short-run Phillips Curve illustrates the inverse relationship, or trade-off, between the rate of inflation and the rate of unemployment in an economy. In the short run, policymakers can often reduce unemployment by stimulating aggregate demand, but this action tends to lead to higher inflation, and vice versa. This relationship breaks down in the long run as expectations adjust, but the short-run curve captures this immediate policy dilemma.

What economic term describes a mandated maximum price a seller can charge for a product or service?
💡 Explanation:A price ceiling is a government-imposed limit on how high a price is permitted to be charged for a good or service. Governments typically implement price ceilings, such as capping airfares, to protect consumers from excessive price increases, particularly during times of crisis or supply shortages.
