Determine the value of the exponents m and n for the equation to be dimensionally consistent. a) m = 3 n = β1
Question
Answer:
Okay, let's check the dimensional consistency of this equation:
Length^m * Time^n
For the equation to be dimensionally consistent, the left and right sides must have the same dimensions.
Length has dimensions of L
Time has dimensions of T
Then:
L^m * T^n must be dimensionless
For L^m to be dimensionless, m must be 0.
For T^n to be dimensionless, n must be -1.
Therefore, the only value of m and n that makes the equation dimensionally consistent is:
m = 0
n = -1
So the answer is:
m = 0
n = -1
(a) is not a dimensionally consistent solution because m should be 0, not 3. Only when m=0, n=-1 is the equation dimensionally consistent with the left and right sides being dimensionless.
