Answer: [M L T-3 K-1].
- A [M L2 T-3 K-1]
- B [M L T-2 K-1]
- C [M L T-3 K-1]
- D [M L2 T-2 K-1]
Correct answer: C. [M L T-3 K-1]
Explanation: k = (Q/t)L/(AΔT) = [M L2 T-3][L]/([L2][K]) = [M L T-3 K-1].
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.
