Answer:
C. Brainstorm
Explanation:
<em>Brainstorming refers to thinking and developing ideas and solutions to problems</em>. It involves a free-thinking approach and putting oneself in the context of the problem you are attempting to solve. You can use the empathy maps to combine ideas from interviewing other people on the same. This stage is followed by defining the problem, concept generation, developing a solution, constructing a testing a prototype, evaluating the solution and finally presenting the solution.
Answer choice A is incorrect because it is the last stage .
Answer choice B is incorrect because it is the second stage.
Answer choice D is incorrect because it is step 5 and 6.

See explanation for step by step procedure to get answer.
Explanation:
Given that:
The conveyor belt is moving downward at 4 m>s. If the coefficient of static friction between the conveyor and the 15-kg package B is ms = 0.8, determine the shortest time the belt can stop so that the package does not slide on the belt.

Answer:
(a). max possible efficiency = 55.62%
(b). max power output = = 133.5 MW
Explanation:
From the question we were given the Maximum temperature in the system as
Tmax = 500°C
Minimum temperature in the system Tmin = 70°C
the Heat supplied to the boiler Qb = 240000 KJ/s
we use the temperature conversion factor from °C to K
given T(K) = T (°C) + 273
⇒ Tmax = 500 + 273 = 773 K
⇒ Tmin = 70 + 273 = 343 K
(a). we are to determine the maximum possible thermal efficiency;
(Πth)max = 1 - Tmin/Tmax
(Πth)max = 1 - 343/773 = 0.5562
(Πth)max = 55.62%
(b). to determine the maximum possible power output for the plant we have;
(Πth)max = Wmax/Qb
where Wmax rep the maximum power output
(Πth)max = 0.5562
Qb = 240000
∴ Wmax = 0.5562 × 240000 = 133505.6 Kw
Wmax = 133.5 MW
