Since the magnetic field of the Earth and the induced field are at right angles, you can use the Pythagorean Theorem to determine the strength of the combined field. This theorem states that the square of the length of a right triangle’s hypotenuse (c) is equal to the sum of the squares of the lengths of the two legs (a and b): a2 + b2 = c2. In this situation, a is the strength of Earth's magnetic field and b is the strength of the induced magnetic field.

Predict and draw: Based on the strength of the field at points (50, 0) and (-50, 0), what do you think the strength of the magnetic field will be at point (0, 50)? -You may draw them on paper or using a digital drawing tool then insert the image to ✏️ show your work below.

In a steady-flow steam power plant system, two adiabatic high-pressure and low-pressure turbines ane used to generate power. superheated steam enters the high-pressure turbine at 8 mpa and 550°c. the steam expands in the high-pressure turbine to a saturated vapor at 3 mpa. in order to increase the powe generation of the power plant, another steam turbine working in a lower pressure ranges is deployed. the outlet vapor from the first turbine is heated up at a boiler to the temperature of 500 c at the constant pressure of first turbine's outlet (3 mpa). then, the vapor enters the second turbine and produces extra work. the exit conditions of the second turbine are 5o kpa and 90 percent quality. if the total power output of the power plant is 25 mw, determine a) the mass flow rate of the water (kg/s). b) heat transfer rate in the boiler (mw).
