Question

254 +8
(a) Using u = 5x + 8
(b) Using u = 75x+8​

Answer 1

Explanation:

Some scales, such as the traditional beam balance, measure mass directly by counteracting the downward force by another equal downward force on the opposite side of the pivot. On a beam balance, you add enough mass to the opposite pan to counterbalance the unknown mass. No force is measured.
