Boilers Mechanical Engineering QUESTION #2409

Question 8

The bulk modulus of elasticity $E$ of a fluid is defined as:

$E = dp/(d\rho/\rho)$
$E = dp/(-dv/v)$ — ratio of pressure increase to fractional volume decrease
$E = \rho c^2$ where $c$ is sound speed
Both options B and C are correct expressions for $E$✔️

Correct Answer Logic:

Bulk modulus $E=-dp/(dV/V)=\rho c^2$. Both definitions are equivalent. For water: $E\approx2.1$ GPa.

Physics QUESTION #1031

Question 9

A particle of mass $m$ moves around the origin under constant force $F$ towards origin. Using Bohr model, how do radius $r$ of $n$th orbit and speed $v$ depend on $n$?

$r \propto n^{2/3};\ v \propto n^{1/3}$✔️
$r \propto n^{4/3};\ v \propto n^{-1/3}$
$r \propto n^{1/3};\ v \propto n^{1/3}$
$r \propto n^{1/3};\ v \propto n^{2/3}$

Correct Answer Logic:

For circular orbit under constant force: $F = \frac{mv^2}{r}\Rightarrow v^2 = \frac{Fr}{m}$. Bohr quantization: $mvr = \frac{nh}{2\pi}\Rightarrow v = \frac{nh}{2\pi mr}$. Substituting: $\frac{F r}{m} = \frac{n^2h^2}{4\pi^2m^2r^2}\Rightarrow r^3 \propto n^2\Rightarrow r \propto n^{2/3}$. Then $v \propto \frac{n}{r} \propto \frac{n}{n^{2/3}} = n^{1/3}$.

Chemistry QUESTION #7350

Question 10

If uncertainty in position $\Delta x$ equals uncertainty in momentum $\Delta p$, then the uncertainty in velocity $\Delta v$ is:

$\sqrt{\dfrac{h}{\pi}}$
$\dfrac{1}{2m}\sqrt{\dfrac{h}{\pi}}$✔️
$\sqrt{\dfrac{h}{2\pi}}$
$\dfrac{1}{m}\sqrt{\dfrac{h}{\pi}}$

Correct Answer Logic:

Heisenberg's Uncertainty Principle: $\Delta x \cdot \Delta p \geq \dfrac{h}{4\pi}$

Given $\Delta x = \Delta p$, so $(\Delta p)^2 = \dfrac{h}{4\pi}$

$\Delta p = \sqrt{\dfrac{h}{4\pi}} = \dfrac{1}{2}\sqrt{\dfrac{h}{\pi}}$

Since $\Delta p = m \cdot \Delta v$:
$\Delta v = \dfrac{\Delta p}{m} = \dfrac{1}{2m}\sqrt{\dfrac{h}{\pi}}$

Mathematics QUESTION #7471

Question 12

If the vectors $\vec{AB} = 3\hat{i} + 4\hat{k}$ and $\vec{AC} = 5\hat{i} - 2\hat{j} + 4\hat{k}$ are the sides of a triangle ABC, then the length of the median through A is:

$\sqrt{18}$
$\sqrt{72}$
$\sqrt{33}$✔️
$\sqrt{45}$

Correct Answer Logic:

The median from A goes to midpoint M of BC. Position vector of B from A is $\vec{AB} = 3\hat{i}+4\hat{k}$, and of C from A is $\vec{AC} = 5\hat{i}-2\hat{j}+4\hat{k}$. Midpoint M has position vector $\frac{\vec{AB}+\vec{AC}}{2} = \frac{(3\hat{i}+4\hat{k})+(5\hat{i}-2\hat{j}+4\hat{k})}{2} = \frac{8\hat{i}-2\hat{j}+8\hat{k}}{2} = 4\hat{i}-\hat{j}+4\hat{k}$. Length of median $AM = |\vec{AM}| = \sqrt{16+1+16} = \sqrt{33}$.
