Physics QUESTION #4412

Question 5162

A loop moves toward a stationary magnet. The induced current will:

Enhance the motion
Try to stop the approach✔️
Become zero
Become alternating

Correct Answer Logic:

By Lenz's law, the induced current opposes the change causing it. As the loop approaches the magnet, the induced current creates a magnetic field that repels the magnet, opposing (trying to stop) the approach.

Chemistry QUESTION #1090

Question 5163

Molar conductivity $\Lambda_m = 90\ \text{S cm}^2\text{mol}^{-1}$ for $0.050\ \text{mol L}^{-1}$ monobasic weak acid. Degree of dissociation: [$\Lambda_+^\circ = 349.6$, $\Lambda_-^\circ = 50.4\ \text{S cm}^2\text{mol}^{-1}$]

0.225✔️
0.215
0.115
0.125

Correct Answer Logic:

$\Lambda_m^\circ = \Lambda_+^\circ + \Lambda_-^\circ = 349.6+50.4=400\ \text{S cm}^2\text{mol}^{-1}$. Degree of dissociation $\alpha = \frac{\Lambda_m}{\Lambda_m^\circ}=\frac{90}{400}=0.225$.

Question 5164

One apple pie has $10$ slices, and each apple pie feeds five people. Henry is having a party with $200$ people. How many slices of pie does he need?

200
50
400✔️
100

Correct Answer Logic:

Each pie feeds $5$ people and has $10$ slices, so each person gets $\dfrac{10}{5} = 2$ slices. For $200$ people: total slices $= 200 \times 2 = 400$ slices.

Mathematics QUESTION #6031

Question 5170

Let $f(x)=\begin{cases}\max\{|x|,x^2\},&|x|\le2\\8-2|x|,&2<|x|\le4\end{cases}$. Let $S$ be the set of points in $(-4,4)$ where $f$ is not differentiable. Find $S$.

Empty set
$\{-2,-1,0,1,2\}$✔️
$\{-2,-1,1,2\}$
$\{-2,2\}$

Correct Answer Logic:

On $[-2,2]$: $\max(|x|,x^2)=x^2$ when $x^2\ge|x|$, i.e., $|x|\ge1$; equals $|x|$ when $|x|\le1$.

So $f(x)=|x|$ for $|x|\le1$ and $f(x)=x^2$ for $1\le|x|\le2$.

Check non-differentiability: At $x=0$: $|x|$ is not differentiable. At $x=\pm1$: left-hand $f'=\pm1$, right-hand $f'=2x=\pm2$ — not equal, so not differentiable. At $x=\pm2$: $f(2^-)=4$, $f(2^+)=4$; $f'(2^-)=4$, $f'(2^+)=-2$ — not differentiable.

So $S=\{-2,-1,0,1,2\}$.

Chemistry QUESTION #5568

Question 5174

An organic compound A reacts with $NH_3$ to give B. On heating, B gives C. C reacts with $Br_2$/KOH to give $CH_3CH_2NH_2$ (ethylamine). Identify compound A.

$CH_3COOH$
$CH_3CH_2CH_2COOH$
$CH_3CH(CH_3)COOH$ (2-methylpropanoic acid)
$CH_3CH_2COOH$✔️

Correct Answer Logic:

Working backwards: $CH_3CH_2NH_2$ (ethylamine) is produced by Hofmann bromamide degradation of $CH_3CH_2CONH_2$ (propionamide). Propionamide (C) is produced by heating propanoic acid ammonium salt (B). B is formed when $CH_3CH_2COOH$ (propanoic acid = A) reacts with $NH_3$. So A = $CH_3CH_2COOH$.

Question 5175

The term 'syneresis' in the context of yoghurt and cheese refers to:

Microbial spoilage causing off-flavors
Contraction of the protein gel network expelling whey✔️
Excessive lactose crystallization causing sandiness
Lipid oxidation causing rancidity

Correct Answer Logic:

Syneresis is the spontaneous contraction of the casein gel/curd matrix expelling entrapped whey. In yoghurt, excessive syneresis causes a watery layer. It is influenced by protein concentration, $\text{pH}$ at gelation, heat treatment of milk, and rate of acidification.

Question 5179

Evaluate: $999^2 - 998 \times 1000$

1✔️
2
3
4

Correct Answer Logic:

Using identity $a^2 - b \times c$: Let $a = 999$, $b=998$, $c=1000$. Note $998 \times 1000 = (999-1)(999+1) = 999^2 - 1$. So $999^2 - (999^2 - 1) = 1$.
