Physics QUESTION #991

A rectangular metallic loop moves out of a uniform magnetic field region into a field-free region at constant speed. When partially inside, the plot of magnitude of induced emf $(\varepsilon)$ with time $(t)$ is:

Linearly increasing graph
Decreasing curve (exponential)
Linearly increasing then constant
Constant (horizontal line)✔️

Correct Answer Logic:

As the loop exits at constant speed, the rate of change of flux is constant ($\varepsilon = Bvl$ = constant). So the emf is constant with time — represented by a horizontal line. Answer key: option (4) = constant horizontal line.

Which sentence uses the APOSTROPHE correctly?

The dogs bone was buried in the garden.
The dog's bone was buried in the garden.✔️
The dogs' bone was buried in the garden.

Bio-Technology QUESTION #10593

Question 4815

Flow injection analysis (FIA) in bioprocess monitoring is most valued for:

In situ measurement of dissolved gases directly in the fermenter
Automated, reproducible, time-discrete chemical analysis of multiple analytes from a sample stream✔️
Continuous real-time measurement with no sampling required
Physical separation of cells from the broth online

Correct Answer Logic:

FIA operates by injecting a precisely measured sample volume into a flowing carrier stream where chemical/enzymatic reactions occur in a plug-flow reactor coil. A detector (photometric, amperometric, or biosensor) measures the reaction product. Key advantages: high automation, reproducibility (~99%), ability to handle complex matrices via dilution, and rapid analysis (<1 min per sample). It interfaces with the fermenter via cross-flow filters, avoiding sterilisation problems.

How many cyclic subgroups does $\mathbb{Z}_{18}$ have?

4
5
6✔️
7

Correct Answer Logic:

The cyclic subgroups of $\mathbb{Z}_{18}$ correspond to divisors of 18: $1, 2, 3, 6, 9, 18$. Each divisor $d$ gives a unique cyclic subgroup $\langle \frac{18}{d} \rangle$ of order $d$. There are 6 divisors, hence 6 cyclic subgroups.
