Given that f = 3u( (1)/(v1) - (1)/(v2)) find the value of u when f is 23 , v1 is 3 , and v2 is 6 ​

Question

Given that


`f = 3u( (1)/(v1) - (1)/(v2))`
find the value of u when f is 23 , v1 is 3 , and v2 is 6


​

Answer 1

substitute the numbers into the equation:
23 = 3u (1/3 - 1/6 )
23 = 3u ( 1/6 )
3.83 = 3u
u = 1.27
