Volume of hemisphere: $\frac{2}{3}\pi R^3$. Volume of cone: $\frac{1}{3}\pi R^2 h$. Total = $\frac{4}{3}\pi R^3$ (sphere volume). So $\frac{2}{3}\pi R^3 + \frac{1}{3}\pi R^2 h = \frac{4}{3}\pi R^3$. Simplifying: $2R + h = 4R$, giving $h = 2R$.

Physics and Math QUESTION #769

Question 8987

$\int x\cos x\, dx = ?$

$x\sin x - \cos x + c$
$x\sin x - \cos x - c$✔️
$x\cos x - \sin x + c$
None

Correct Answer Logic:

Using integration by parts: $\int x\cos x\, dx = x\sin x - \int \sin x\, dx = x\sin x + \cos x + c$. Note: The paper marks option B ($x\sin x - \cos x - c$) but the standard result is $x\sin x + \cos x + c$.

Physics QUESTION #1189

Question 8991

The Ultraviolet catastrophe means:

The spectral energy concentration towards longer wavelength.
The spectral energy concentration at the middle of the spectrum.
The spectral energy concentration towards shorter wavelength side.✔️
None of these

Correct Answer Logic:

The ultraviolet catastrophe was a prediction of classical physics (Rayleigh-Jeans law) that a blackbody should radiate infinite energy at very short (ultraviolet) wavelengths: $u(\nu) \propto \nu^2 T$. The spectral energy density was predicted to increase without bound towards shorter wavelengths, which was catastrophically wrong and was resolved by Planck's quantum hypothesis.

Bio-Technology QUESTION #10594

Question 8996

The industrial production of L-glutamate by Corynebacterium glutamicum requires a culture condition that triggers product secretion. This is achieved by:

Addition of penicillin or biotin limitation to permeabilise the cell membrane✔️
Increasing dissolved oxygen tension above 80% saturation
Growing cells under strictly anaerobic conditions
Adding chloramphenicol to inhibit protein synthesis

Correct Answer Logic:

C. glutamicum normally retains glutamate intracellularly. Secretion is triggered by membrane permeabilisation via: (1) biotin limitation (alters membrane fatty acid composition, reducing membrane integrity), or (2) addition of penicillin (inhibits peptidoglycan synthesis) or detergents. This allows glutamate — produced in excess via the TCA cycle and GOGAT pathway — to leak out, making fermentation profitable. Global MSG production exceeds 2 million tonnes/year.

MBBS QUESTION #10205

Question 8997

A newborn boy is noted to have an empty scrotum with the testis palpable at a point along its normal path of descent. If the testis has failed to complete its descent by birth, it is most commonly arrested within which structure?

The inguinal canal✔️
The pelvic cavity, near the bladder
It has descended fully into the scrotum
The retroperitoneum, near the kidney

Correct Answer Logic:

Cryptorchidism most commonly involves arrest of testicular descent within the inguinal canal, reflecting incomplete traction/guidance by the gubernaculum; undescended testes carry an increased risk of infertility and germ cell tumors if uncorrected.

General Knowledge QUESTION #2608

Question 8998

In the decimal system (base-10), which statement is CORRECT?

You can use digits 0 through 8 only (9 digits total)
You can use digits 0 through 9 (10 digits total)✔️
You can use digits 1 through 10 (10 digits total)
You can use digits 0 through 10 (11 digits total)

Correct Answer Logic:

In the decimal system, there are exactly 10 possible digit symbols ranging from zero (0) to nine (9). The number 10 itself is NOT a single digit — it is composed of two digits (1 and 0). This is why the system is called 'base-10'.
