Answer: √(ħG/c⁵).
- A √(ħG/c⁵)
- B √(ħG/c³)
- C √(ħc/G)
- D √(ħG/c)
Correct answer: A. √(ħG/c⁵)
Explanation: √(ħG/c⁵) is the Planck time, having the dimension of time.
The 7 SI base units. All derived units (newton, joule, watt, volt, etc.) can be expressed as combinations of these 7 fundamental units raised to various powers.
Concept context
SI base units, dimensional analysis, significant figures, and error propagation. The toolkit every physics calculation relies on.
