Economics QUESTION #1692

In the IS-LM model of macroeconomic equilibrium, the LM curve traces out all combinations of income and interest rates at which:

The goods and services market is in equilibrium
The government budget is balanced
The money market (financial market) is in equilibrium✔️
None of these

Correct Answer Logic:

The LM curve (L = Liquidity preference, M = Money supply) represents all combinations of real income (Y) and interest rate (r) at which the money market is in equilibrium — where money demand equals money supply ($L(Y, r) = M/P$). As income rises, money demand increases, requiring a higher interest rate to maintain equilibrium. The IS curve represents equilibrium in the goods market.

Question 8

In a gaseous mixture, the ratio of masses of oxygen to nitrogen is 1 : 4. What is the ratio of the number of molecules of O$_2$ to N$_2$?

1:08
3:16
1:04
7:32✔️

Correct Answer Logic:

Let mass of O$_2 = 1$ g and mass of N$_2 = 4$ g.

Moles of O$_2 = \dfrac{1}{32}$ ; Moles of N$_2 = \dfrac{4}{28} = \dfrac{1}{7}$

Ratio $= \dfrac{1/32}{1/7} = \dfrac{7}{32}$

So the ratio of molecules O$_2$ : N$_2 = \mathbf{7 : 32}$

Question 10

The standard second-order closed-loop transfer function is written as:

$Y(s) = \frac{2\zeta\omega_n}{s^2+2\zeta\omega_n s+\omega_n^2}$
$Y(s) = \frac{\omega_n^2}{s^2+2\zeta\omega_n s+\omega_n^2}$✔️
$Y(s) = \frac{\omega_n^2}{s^2+\omega_n^2}$
$Y(s) = \frac{1}{s^2+2\zeta s+1}$

Correct Answer Logic:

The standard second-order system: $Y(s)=\frac{\omega_n^2}{s^2+2\zeta\omega_n s+\omega_n^2}$ where $\omega_n$ is the undamped natural frequency and $\zeta$ is the damping ratio. Poles: $s=-\zeta\omega_n\pm\omega_n\sqrt{\zeta^2-1}$.

Question 14

In a beam with a very thin web, 'Tension Field Action' can be utilized to carry shear forces after the web has buckled. This is analogous to the behavior of:

A suspension bridge cable
A Pratt truss with tension diagonals✔️
A concrete arch
A cantilevered column

Correct Answer Logic:

Tension field action occurs in plate girders where the web buckles under shear, and the post-buckling strength is developed by diagonal tension fields (the web acts like the tension diagonals of a truss).

Sociology QUESTION #1663

Question 20

Structural Functionalism
Symbolic Interactionism
Marxist historical materialism✔️
Rational Choice Theory

Correct Answer Logic:

In Marxist theory, the 'base' refers to the economic infrastructure — the means and relations of production — while the 'superstructure' encompasses all other social institutions (law, religion, politics, culture) that arise from and serve to legitimize the base.
