An acb sequence balanced three-phase y-connected source supplies power to a balanced, three-phase δ-connected load with an impedance of 15+15i ω/ϕ . the source voltage in the b-phase is 250 ∠−45∘v. the line impedance is 1 + 1i ω/ϕ. use the single phase equivalent circuit for the a-phase to find the current in the a-phase of the load.

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only

answer:

explanation:

An artesian well is simply a well that doesn't require a pump to bring water to the surface; this occurs when there is enough pressure in the aquifer. The pressure forces the water to the surface without any sort of assistance.
