Answer: [M L-1 T-1].
- A [M L-1 T-2]
- B [M L T-1]
- C [M L-1 T-1]
- D [M L-2 T-1]
Correct answer: C. [M L-1 T-1]
Explanation: From F = 6πηrv, η = F / (rv) = [M L T-2] / ([L][L T-1]) = [M L-1 T-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.
