Physics QUESTION #1184

Question 3

The Lorentz force is given by:

F = q(v × B)✔️
Φ = ∂A/∂x + ∂A/∂y + ∂A/∂z
qF = q(v_d × B)
None of these

Correct Answer Logic:

The Lorentz force on a charge $q$ moving with velocity $\vec{v}$ in a magnetic field $\vec{B}$ is $\vec{F} = q(\vec{v} \times \vec{B})$. The full Lorentz force including the electric field is $\vec{F} = q(\vec{E} + \vec{v} \times \vec{B})$. Option (B) is the divergence of vector potential (unrelated), and option (C) has incorrect notation.

In a civil case, the court takes 'judicial notice' of the fact that it was raining in the city on July 4th, 2023, based on certified weather records. The court instructs the jury that they 'must accept this fact as conclusive.' Is this instruction proper?

No, in civil cases, the jury has the discretion to reject judicially noticed facts.
Yes, in civil cases, the court must instruct the jury to accept a judicially noticed fact as conclusive under Rule 201(f).✔️
No, judicial notice is only for 'law,' not 'facts.'
Yes, but only if the parties stipulated to the fact beforehand.

Laissez-faire
Democratic (Participative)

While this style can be efficient in crises or with inexperienced teams, it can reduce morale and creativity. Kurt Lewin's three styles are Autocratic, Democratic (Participative), and Laissez-faire (hands-off).

Physics QUESTION #5586

Question 12

A room is supplied with electricity at 120 V. The lead wires have a total resistance of $6\,\Omega$. A 60 W bulb is already running. What is the decrease in voltage across the bulb when a 240 W heater is switched on in parallel with the bulb?

Zero Volt
2.9 Volt
13.3 Volt
10.04 Volt✔️

Correct Answer Logic:

Resistance of the bulb: $R_b = \frac{V^2}{P} = \frac{(120)^2}{60} = 240\,\Omega$

Before heater is switched on: Current $= \frac{120}{240+6} = \frac{120}{246}\,\text{A}$. Voltage across bulb $= \frac{120 \times 240}{246} \approx 116.9\,\text{V}$.

Resistance of heater: $R_h = \frac{(120)^2}{240} = 60\,\Omega$. Parallel combination: $R_p = \frac{240 \times 60}{300} = 48\,\Omega$.

After heater is switched on: Voltage across combination $= \frac{120 \times 48}{48+6} = \frac{5760}{54} \approx 106.67\,\text{V}$.

Decrease $= 116.9 - 106.67 \approx 10.04\,\text{V}$. Answer: D.

Economics QUESTION #1687

Question 18

The theory of absolute advantage in international trade — arguing that nations should export goods they produce most efficiently — was originally articulated by:

Alfred Marshall
Adam Smith✔️
Lionel Robbins
None of these

Correct Answer Logic:

Adam Smith introduced the theory of absolute advantage in his landmark 1776 work 'The Wealth of Nations.' He argued that international trade is mutually beneficial when each country specialises in producing goods it can produce more efficiently (at lower absolute cost) than others. David Ricardo later extended this to comparative advantage. Alfred Marshall contributed to marginal utility theory; Lionel Robbins defined economics as the science of scarcity.
