UGC NET 2023 Paper 1 Question Paper (22-Jun-2023) (Shift 2)
The correct answer is

B, D, C, E, A

To solve this question, we need to list the given measurement units in descending order of size. Let's first understand each prefix:

  • Tera (T): Represents \(10^{12}\).
  • Kilo (k): Represents \(10^{3}\).
  • Micro (µ): Represents \(10^{-6}\).
  • Pico (p): Represents \(10^{-12}\).
  • Atto (a): Represents \(10^{-18}\).

Now, listing them in descending order of their magnitudes:

  1. Tera (\(10^{12}\))
  2. Kilo (\(10^{3}\))
  3. Micro (\(10^{-6}\))
  4. Pico (\(10^{-12}\))
  5. Atto (\(10^{-18}\))

Based on the above arrangement, we can see that the correct order from largest to smallest is:

  1. B (Tera)
  2. C (Kilo)
  3. D (Micro)
  4. E (Pico)
  5. A (Atto)

Therefore, the correct answer according to the options provided is: B, D, C, E, A.
