Which of the following industries generate non-biodegradable wastes?
1) Cotton mills
(2) Paper mills
(3) Thermal power plants
(4) Textile factories
Textile factories
Step 1: Understanding Non-Biodegradable Waste
Non-biodegradable waste refers to materials that do not decompose naturally and persist in the environment for a long time, causing pollution. These include plastics, heavy metals, industrial chemicals, and fly ash.
Step 2: Analyzing the Given Industries
1. Cotton mills: Incorrect. Cotton mills primarily generate biodegradable waste, such as natural fiber residues.\ 2. Paper mills: Incorrect. Paper waste is mostly biodegradable and recyclable.
3. Thermal power plants: Correct. These plants generate large amounts of non-biodegradable waste such as fly ash, bottom ash, and heavy metal residues, which contribute to environmental pollution.
4. Textile factories: Incorrect. Textile waste can include biodegradable materials like natural fibers, though synthetic fibers may persist longer. Step 3: Evaluating the Given Options
- Option (1): Incorrect, as cotton waste is biodegradable.
- Option (2): Incorrect, as paper is mostly biodegradable.
- Option (3): Correct, as thermal power plants generate non-biodegradable industrial waste.
- Option (4): Incorrect, as textile waste varies, but most of it is biodegradable.
Thus, the correct answer is
Option (3).
The IUPAC name of the following compound is:
\[ \text{The domain of the real-valued function } f(x) = \sin^{-1} \left( \log_2 \left( \frac{x^2}{2} \right) \right) \text{ is} \]
Let \( A = [a_{ij}] \) be a \( 3 \times 3 \) matrix with positive integers as its elements. The elements of \( A \) are such that the sum of all the elements of each row is equal to 6, and \( a_{22} = 2 \).
\[ \textbf{If } | \text{Adj} \ A | = x \text{ and } | \text{Adj} \ B | = y, \text{ then } \left( | \text{Adj}(AB) | \right)^{-1} \text{ is } \]
