Answer:
I will choose the answer A
Answer:
The high-leg voltage is
Explanation:
A diagram showing the arrangement of this three phase transformer is shown on the first uploaded image
The high - leg terminal is in the diagram is from
Generally the high-leg terminal is 1.732 times of the the voltage from line to center tap which is given as 277 V
The high -voltage can be computed as follows
Answer:
The magnitude of displacement is 591km
Explanation:
Displacement is the change in an object's position from the origin. Displacement is a vector quantity, and thus has both magnitude and direction.
D = Xf - Xi = ∆X
Where D is displacement
Xf = final position
Xi = initial position
∆X = Change in position
The cars initial position Xi = 0
The cars finial velocity is (Distance traveled West - Distance traveled North)
Therefore D = (1250 W - 659 N) - 0
D = 591km N
Complete Question
A real (non-Carnot) heat engine, operating between heat reservoirs at temperatures of 650 K and 270 K and performs 4.3 kJ of net work and rejects 8.00 kJ of heat in a single cycle. The thermal efficiency of this heat engine is closest to A) 0.35 B) 0.31. C) 0.28. D) 0.38. E) 0.42.
Answer:
The correct option is A
Explanation:
From the question we are told that
The first operating temperature is
The second operating temperature is
The net workdone is ( output of the engine )
The amount of heat energy rejected is
Generally a heat engine convert heat from a high temperature to mechanical energy and then reject the remaining heat so the absorbed by the engine is
Generally the thermal efficiency is mathematically represented as
Here out is the output of the engine
and in is the input of the engine

Answer:
Backwash effect
Explanation:
Your friend moved along the shore due to ; The swash effect and the Backwash effect
Swash effect is caused by the upsurge of water up along the slopping front of the beach and this same upsurge in water moves back into the beach in what is known as the backwash effect hence the movement of your friend form where they were in the surf zone to another position still within the surface zone is caused by the BACKWASH EFFECT
