Physics QUESTION #7019

Question 8

Calculate the ratio of the root mean square ($rms$) velocities of Helium and Argon atoms, given that the atomic mass of Helium is $4\text{ u}$ and Argon is $40\text{ u}$, both at the same temperature.

$3.16$✔️
$0.32$
$0.45$
$2.24$

Correct Answer Logic:

The $rms$ velocity is given by $v_{rms} = \sqrt{\frac{3RT}{M}}$. Since $T$ is constant, the ratio is inversely proportional to the square root of the molar masses: $\frac{v_{He}}{v_{Ar}} = \sqrt{\frac{M_{Ar}}{M_{He}}} = \sqrt{\frac{40}{4}} = \sqrt{10} \approx 3.16$.

Mathematics QUESTION #965

Question 10

Let a line pass through two distinct points $P(-2,-1,3)$ and $Q$, and be parallel to the vector $3\hat{i}+2\hat{j}+2\hat{k}$. If the distance of the point $Q$ from the point $R(1,3,3)$ is 5, then the square of the area of $\triangle PQR$ is equal to:

148
136
144
140✔️

Correct Answer Logic:

The line through $P$ parallel to $\vec{v}=3\hat{i}+2\hat{j}+2\hat{k}$ gives $Q = P + t\vec{v}$. Using $|QR|=5$ to find $t$, then computing $\text{Area}^2 = \frac{1}{2}|\vec{PQ}\times\vec{PR}|^2$ yields 140.

Education QUESTION #6784

Question 14

A test item reads: 'Which of the following is NOT an example of formative assessment?' with correct answer option 'Final examination'. A student incorrectly answers 'Weekly quiz'. According to item analysis in CTT, if students with high total test scores systematically choose 'weekly quiz' as their answer, what does the discrimination index likely indicate?

A high positive D value, indicating the item works well
A negative D value, indicating that the item functions in reverse — high achievers are misled while lower achievers answer correctly — suggesting the item needs immediate review✔️
A D value near 0, indicating the item has no differential effect
A D value above 0.40, indicating excellent item quality

Correct Answer Logic:

If high-scoring students are more likely to answer incorrectly than low-scoring students, the item discrimination index D = (Upper Group % Correct) – (Lower Group % Correct) will be negative. Negative D values are the most serious item analysis warning sign, typically indicating a keying error, ambiguous wording, or a misleading clue that advantageously targets lower-ability guessers over informed higher-ability students.

Physics QUESTION #993

Question 18

A body of mass 100 g moves in a circular path of radius 2 m on a vertical plane. The velocity at point $A$ (bottom) is $10\ \text{m/s}$. The ratio of kinetic energies at point $B$ (at $30°$ from bottom) and $C$ (at top, $90°$ from $A$) is: (Take $g = 10\ \text{m/s}^2$):

$\dfrac{2+\sqrt{2}}{3}$
$\dfrac{2+\sqrt{3}}{3}$✔️
$\dfrac{3+\sqrt{3}}{2}$
$\dfrac{3-\sqrt{2}}{2}$

Correct Answer Logic:

Using energy conservation: $KE_B = KE_A - mgh_B$ and $KE_C = KE_A - mgh_C$. Height of B: $h_B = r - r\cos30° = 2(1-\frac{\sqrt{3}}{2})$. Height of C: $h_C = r = 2$ m. Ratio $\frac{KE_B}{KE_C} = \frac{5-mg(2-\sqrt{3})}{5-mg\cdot2} = \frac{2+\sqrt{3}}{3}$.

Question 19

The uterine tubes terminate in a hollow muscular organ positioned in front of the rectum and behind the urinary bladder, which is called the:

Uterus✔️
Vagina
Cervix
Endometrium

Correct Answer Logic:

The uterus is the hollow, thick-walled muscular organ where implantation of the fertilised egg and foetal development occur. It is positioned in the pelvic cavity anterior to the rectum and posterior to the urinary bladder. The uterine (Fallopian) tubes open into its superior angles. The cervix is the lower, narrow portion of the uterus; the vagina is the birth canal; the endometrium is the inner lining of the uterus.

Question 20

The boundary value problem $u_{xx}+u_{yy}=0$ with $u=0$ on three sides and $u(x,b)=f(x)$ is solved by the method of:

Finite differences
Separation of variables✔️
Euler's method
Newton-Raphson

Correct Answer Logic:

The Laplace equation $u_{xx}+u_{yy}=0$ on a rectangle with homogeneous Dirichlet conditions on three sides is a classic problem solved by separation of variables. Assuming $u(x,y)=X(x)Y(y)$ and applying boundary conditions leads to a Fourier sine series solution.
