Assume that a product goes through three sequential processes a, b, and c. moreover, assume that each process takes 3 minutes per unit. currently, there is an order for 5 units of this product to be produced. if the manufacturer employs a one-piece flow system, what is the earliest time for completing the first unit of this product? select one: a. 9 minutes b. 45 minutes c. 15 minutes d. 36 minutes e. 6 minutes

because if the tool that you are using is not balanced it there would be false mass.

answer: the potential energy decreases from 379 j to 243 j

explanation:

for the law of conservation of energy, the total energy in a system must be conserved. the total energy of the system is given by the sum of kinetic (k) and potential (u) energy:

e = k + u

the total energy is e=675 j, and this does not change.

initially, the kinetic energy is k=296 j, so the potential energy is

at the end, the kinetic energy is k=432 j, so the potential energy is

so, we see that the potential energy has decreased from 379 j to 243 j.
