Answer:
technician A is correct
Explanation:
Technician B has circuit topologies confused. In a series circuit, there is only one path for electrical current to take. In a parallel circuit, the current will divide between paths in proportion to the inverse of their resistance. The least resistance path will have the most current.
Technician A is mostly correct.
Answer:
D. Overrule any other laws and traffic control devices.
Explanation:
Laws and traffic control devices are undoubtedly compulsory to be followed at every point in time to control traffic and other related situations. However, there are cases when certain instructions overrule these laws and traffic control devices. For example, when a traffic police is giving instructions, and though the traffic control devices too (such as traffic lights) are displaying their own preset lights to control some traffic, the instructions from the traffic police take more priority. This is because at that point in time, the instructions from the traffic control devices might not be just applicable or sufficient.
Also, in the case of instructions given by construction flaggers, these instructions have priority over those from controlling devices. This is because during construction traffic controls are redirected from the norms. Therefore, the flaggers such be given more importance.
Answer:
1.52 kw
Explanation:
A1 = 0.45
A1 = 0.25
Flow rate = 1.5m³/sec
P1 = 105
P2 = 106
P-air = 1.225kg/m³
I applied bernoulli's equation as I continued (check the attachment)
hp = 83.21371+1.3686 = 84.4823
Pf = p-air x g x Q x hp
Pf = 1.225x9.81x1.5x84.4823
Pf = 1522.868W
When converted to KW we get
Pf = 1.52 KW
Thank you!
Answer:
800.24
Explanation:
National Electrical Code (NEC), articles 725.143 and 800.24 permit attaching the low-voltage thermostat cable to the EMT that brings power to the furnace in accordance with with NEC 300.11.
