To monitor the breathing of a hospital patient, a thin belt is girded around the patient's chest. The belt is a 200-turn coil. When the patient inhales, the area encircled by the coil increases by \( 45.0 \mathrm{~cm}^{2} \). The magnitude of the Earth's magnetic field is \( 50.0 \mu \mathrm{~T} \) and makes an angle of \( 28.0^{\circ} \) with the plane of the coil. Assuming a patient takes 1.89 s to inhale, find the average induced emf in the coil during this time interval. 21.02

A slowly moving engine bumps into a string of coupled railroad cars standing on a siding. A wave pulse is transmitted down the string of cars as each one bumps into the next one. What type of wave is this? Multiple Choice a mix of transverse anditudinal

\( 8 \Rightarrow 12 \) Se tiene una tubería de \( \Phi=2.0 \mathrm{~m} \) en un punto a 320 m sobre el nivel del mar, el agua posee una velocidad de \( 12.0 \mathrm{~m} / \mathrm{s} \) y una presión de 45 m . El agua sale de la turbina con una velocidad de \( 1.8 \mathrm{~m} / \mathrm{s} \) y a presión atmosférica en un punto a 260 m sobre el nivel de mar. ¿Qué valor tiene la potencia que toma la turbina?
