Asmall compass is held horizontally, the center of its needle a distance of 0.278 m directly north of a long wire that is perpendicular to the earth's surface. when there is no current in the wire, the compass needle points due north, which is the direction of the horizontal component of the earth's magnetic field at that location. this component is parallel to the earth's surface. when the current in the wire is 25.5 a, the needle points 22.3° east of north. what is the magnitude of the horizontal component of the earth's magnetic field at the location of the compass?

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)

It is really hard for me right know

In a series circuit the __ is the same at every point
