Question

Given: Av = 2.8 Au and v u = 3. 4 when

If u varies from u change in u is: 3 to u 3.8, the
A. 0.3
B. 0.4
C. 0.5
D. 0.8

Answer 1

The change in variable u is calculated by subtracting the initial value from the final value (3.8 - 3), which gives us a change of 0.8.

Step-by-step explanation:

The question appears to have a typographical error but seems to be asking about the change in variable u (∆u). To find the change in u, we simply subtract the initial value of u from the final value of u.

Initial value of u (ui): 3
Final value of u (uf): 3.8
Change in u (∆u): uf - ui = 3.8 - 3 = 0.8.

The change in u is 0.8. Therefore, the correct answer is D. 0.8.
