Question 4184

Over-applied overhead means:

Actual overheads are less than applied overheads.✔️
Actual overheads are greater than applied overheads.
Fixed costs were not allocated properly.
Direct labor costs were overstated.

Correct Answer Logic:

Overhead is applied to production using a predetermined rate. Over-applied overhead occurs when the applied overhead (predetermined rate × actual activity) exceeds the actual overhead incurred. In other words, actual overheads < applied overheads. This means production was charged more overhead than was actually spent.

Chemistry QUESTION #1078

Question 4193

Statement I: Ferromagnetism is considered as an extreme form of paramagnetism. Statement II: The number of unpaired electrons in Cr$^{2+}$ ion ($Z=24$) is the same as that of Nd$^{3+}$ ion ($Z=60$).

Statement I is true but Statement II is false✔️
Statement I is false but Statement II is true
Both Statement I and Statement II are true
Both Statement I and Statement II are false

Correct Answer Logic:

Statement I is true — ferromagnetism arises from cooperative alignment of magnetic dipoles in domains, and is indeed an extreme form of paramagnetism. Statement II: Cr$^{2+}$ ([Ar]3d$^4$) has 4 unpaired electrons. Nd$^{3+}$ ([Xe]4f$^3$) has 3 unpaired electrons. They are NOT the same. Statement II is false.

Physics and Math QUESTION #757

Question 4196

A small parallel resistance (shunt) used to convert a galvanometer into an ammeter is given by:

Rs = (Ig/(I-Ig)) x Rg✔️
Rs = (Ig-I)/Ig
Rs = Ig/(I-Iθ)
None

Correct Answer Logic:

The shunt resistance Rs = IgRg/(I-Ig). This ensures most current bypasses the galvanometer making it function as an ammeter.

Physics QUESTION #984

Question 4197

The torque due to the force $(2\hat{i}+\hat{j}+2\hat{k})$ about the origin, acting on a particle whose position vector is $(\hat{i}+\hat{j}+\hat{k})$, would be:

$\hat{i}-\hat{k}$✔️
$\hat{i}+\hat{k}$
$\hat{j}+\hat{k}$
$\hat{i}-\hat{j}+\hat{k}$

Correct Answer Logic:

$\vec{\tau} = \vec{r}\times\vec{F} = (\hat{i}+\hat{j}+\hat{k})\times(2\hat{i}+\hat{j}+2\hat{k})$. Computing the determinant: $\hat{i}(1\cdot2-1\cdot1)-\hat{j}(1\cdot2-1\cdot2)+\hat{k}(1\cdot1-1\cdot2) = \hat{i}(1)-\hat{j}(0)+\hat{k}(-1) = \hat{i}-\hat{k}$.

Mechanical Engineering QUESTION #2449

Question 4200

Critical speed of a rotating shaft is the shaft speed at which:

$p = \omega_n$ — the rotational speed equals the shaft's natural lateral frequency, causing resonance✔️
The shaft material yields due to torsional stress
The bearing clearance exceeds the shaft deflection
The shaft temperature reaches a critical value

Correct Answer Logic:

The critical speed of a rotating shaft is when $p=\omega_n$, i.e., the spin speed equals the natural frequency of lateral vibration. At this speed, even small imbalance causes large deflections.
