You can use digits 0 through 8 only (9 digits total)
You can use digits 0 through 9 (10 digits total)✔️
You can use digits 1 through 10 (10 digits total)

Correct Answer Logic:

Physics QUESTION #998

Question 4

A light source of wavelength $\lambda$ illuminates a metal and electrons are ejected with maximum KE of 2 eV. If the same surface is illuminated by wavelength $\dfrac{\lambda}{2}$, the maximum KE of ejected electrons will be (work function $= 1\ \text{eV}$):

3 eV
2 eV
6 eV
5 eV✔️

Correct Answer Logic:

From first case: $\frac{hc}{\lambda} = \phi + 2 = 1+2 = 3\ \text{eV}$. With $\frac{\lambda}{2}$: energy $= \frac{2hc}{\lambda} = 6\ \text{eV}$. Max KE $= 6 - 1 = 5\ \text{eV}$.

Boilers Mechanical Engineering QUESTION #2458

Question 5

The module $m$ of a gear in SI units is defined as:

Number of teeth per millimeter of pitch diameter

Diametral pitch in inverse millimeters

Correct Answer Logic:

Module $m = d/N$ (pitch diameter in mm per tooth). The relationships are: $m = 25.4/P_d$ and $p \cdot P_d = \pi$ (English); $p/m = \pi$ (SI).

Quantitative Reasoning QUESTION #8125

Question 15

The (i)_______ of Vladimir Nabokov as one of North America's literary giants has redirected attention to his secondary activities and has thus served to (ii)_______ his efforts as an amateur entomologist.

lionization .. foreground
stigmatization .. foreground
marginalization .. obscure
lionization .. obscure✔️

Correct Answer Logic:

Being celebrated as a literary giant (lionization = treating someone as a celebrity) would draw attention to his main literary work — which in turn pushes his minor hobby into the background. Therefore his entomology work gets obscured (hidden/overshadowed). 'Stigmatization' means being disgraced — opposite of being a celebrated giant. 'Foreground' would mean highlighting his entomology, which contradicts the logic of the sentence.
