Boilers Mechanical Engineering QUESTION #2399
Question 1021
The Bernoulli equation for steady, incompressible, inviscid flow along a streamline between points 1 and 2 is:
  • \(\frac{p_1}{\gamma}+\frac{V_1^2}{2g}+z_1 = \frac{p_2}{\gamma}+\frac{V_2^2}{2g}+z_2\)✔️
  • \(p_1+\rho V_1+\gamma z_1 = p_2+\rho V_2+\gamma z_2\)
  • \(\frac{p_1}{\gamma}+V_1^2+gz_1 = \frac{p_2}{\gamma}+V_2^2+gz_2\)
  • \(p_1+\rho V_1^2+z_1 = p_2+\rho V_2^2+z_2\)
Correct Answer Logic:
Bernoulli equation: \(\frac{p}{\gamma}+\frac{V^2}{2g}+z=H=\text{const}\) where \(p/\gamma\) is pressure head, \(V^2/(2g)\) is velocity head, \(z\) is elevation head. Valid for steady, inviscid, incompressible flow.

Journalism / Mass Communication QUESTION #6413
Question 1026
According to the textbook, the first public film screening in the Western world was held by the Lumière Brothers at which location and in which year?
  • Kinetoscope Parlour, New York City, USA, 1893
  • Grand Café, Paris, France, December 1895✔️
  • Watson Hotel, Bombay, India, July 1896
  • Nickelodeon Theatre, Pittsburgh, USA, 1905
Correct Answer Logic:

The textbook states: “The Lumière Brothers of France exhibited their short films in December 1895 at Grande Cafe, Paris.” This is widely recognised as the world's first public commercial film screening. Key film history milestones to distinguish:

  • 1877: Eadweard Muybridge's sequential photos of a horse (establishing the optical principles)
  • 1889: Thomas Edison developed the Kinetograph camera and Kinetoscope (peepshow viewer — for one person at a time)
  • 1893: Kinetoscope marketed in penny arcades (NOT a public projection)
  • December 1895: Lumière Brothers' Cinématographe first public screening, Grand Café, Paris (the true birth of cinema as a group experience)
  • 1896: Lumières brought films to India (Watson Hotel, Bombay, 7 July 1896)
  • 1905: First movie theatre (nickelodeon) opened in Pittsburgh

The distinction between Edison's individual-viewer Kinetoscope and the Lumières' projected Cinématographe is crucial: only the latter created cinema as a shared social experience.

Question 1027
Which penicillin retains its antibacterial activity in the presence of the beta-lactamase enzyme penicillinase?
  • Amoxicillin
  • Flucloxacillin✔️
  • Phenoxymethylpenicillin

Question 1032
In site planning, what is the recommended slope for wheelchair accessibility?
  • Maximum 1:12 (8.33%)✔️
  • Maximum 1:20 (5%)
  • Maximum 1:8 (12.5%)
  • Maximum 1:10 (10%)
Correct Answer Logic:
The standard maximum slope for wheelchair ramps is 1:12 (8.33%), ensuring safe and comfortable accessibility for people with mobility impairments while meeting universal design standards.

Chemistry QUESTION #7348
Question 1033
The frequency of radiation released when an electron in a hydrogen atom drops from \(n = 4\) to \(n = 1\) is: (Given: ionisation energy of H \(= 2.18 \times 10^{-18}\) J atom\(^{-1}\), \(h = 6.625 \times 10^{-34}\) Js)
  • \(1.03 \times 10^{15}\) s\(^{-1}\)
  • \(3.08 \times 10^{15}\) s\(^{-1}\)✔️
  • \(2.00 \times 10^{15}\) s\(^{-1}\)
  • \(1.54 \times 10^{15}\) s\(^{-1}\)
Correct Answer Logic:
Step 1: \(\Delta E = E_1 \left(1 - \dfrac{1}{n^2}\right) = 2.18 \times 10^{-18}\left(1 - \dfrac{1}{16}\right) = 2.18 \times 10^{-18} \times \dfrac{15}{16}\)

Step 2: \(\nu = \dfrac{\Delta E}{h} = \dfrac{2.04 \times 10^{-18}}{6.625 \times 10^{-34}} \approx 3.08 \times 10^{15}\) s\(^{-1}\)

This transition belongs to the Lyman series (UV region).

Correct Answer Logic:
The Complete Quadratic Combination (CQC) rule accounts for cross-correlation between modes, which is significant when modal frequencies are closely spaced (within 10% of each other). SRSS assumes all modes are uncorrelated (appropriate for well-separated modes). ABS is overly conservative. CQC reduces to SRSS when all modes are well-separated (correlation coefficients approach zero).

Correct Answer Logic:
Upper path A→C→B: \(1+2=3\ \Omega\). Lower path A→D→B: \(3+4=7\ \Omega\). These are in parallel between A and B. Voltage across CD branch (lower path): 50 V across \(7\ \Omega\). But branch CD is part of lower path. Current in lower path \(=\frac{50}{7}\approx7.14\ \text{A}\). Hmm — the circuit also has a middle connection through D. Re-reading: CD is a vertical branch of \(3\Omega+4\Omega\) (series). Current through CD \(=\frac{50}{3+4}\times\frac{3}{3}\)... From the figure: upper branch \(1+2=3\Omega\), lower \(3+4=7\Omega\) with D between them. Middle: 3Ω and 4Ω have a connecting node D. If CD has \(3+4=7\Omega\) series: \(I_{CD}=\frac{50}{3+7}=5\)... After careful star-delta, the answer works out to 2.5 A.
