Uhm I’m not understanding the question
Answer:
option B
Explanation:
The correct answer is option B
Seaming is an operation in which the edges are folded over another part to achieve the tight fit.
Seaming is generally used to join other parts together.
So, seaming is generally used for producing fluid-tight joints.
This process is used in the food industry on canned goods, metal roofing, and in the automotive industry.
Answer:
0.0833 k J/k
Explanation:
Given data in question
total amount of heat transfedded (Q) = 100 KJ
hot reservoir temperature R(h) = 1200 K
cold reservoir temperature R(c) = 600 k
Solution
we will apply here change of entropy (Δs) formula
Δs = 
Δs = 
Δs = 
Δs = 0.0833 K J/k
this change of entropy Δs is positive so we can say it is feasible and
increase of entropy principle is satisfied
Probably because it’s metal and metal is a better thermal conductor
Answer:
Explanation:
To obtain 240 V from 12 V batteries they must be connected in series. The number needed is ...
240/12 = 20 . . . batteries needed
__
The current draw will be ...
(3000 W)/(240 V) = 12.5 A
Then the time available from the battery stack is ...
(120 Ah)/(12.5 A) = 9.6 h
The motor can run 9.6 hours from the series connection.
