The dimensions of volume and acceleration (respectively) are:
Correct answer: C. L3 and LT-2
- A. LT-1
- B. LT-2 and LT-1
- C. L3 and LT-2
- D. L4 T-1 and LT
- E. LT3 and T2
Explanation
The following is the solution:Volume is equal to L x L x L=L3 Acceleration is equal to the rate of changeof velocity=Velocity/Time; ->Since velocity is equal to Distancetravelled/Time=L/T=LT-1 Plug these units into the formula ofacceleration=LT-1/T=LT-2. Hence the units are: L3 and LT-2

About Measurements
Physical quantities are expressed with SI base and derived units, while measurement limits are described through accuracy, precision, absolute and percentage error, and significant figures. Dimensional analysis checks equations, derives relationships and detects inconsistent units, but it cannot determine numerical constants or distinguish quantities with identical dimensions.
