El inducido de un generador eléctrico bipolar consta de una núcleo cilíndrico de 20cm de longitud y 10cm de diámetro, sobre donde va arrollado 200 espiras dispuestas en dos circuitos en paralelo la inducción magnética en el entre hierro es de medio . Calcular la fem media generada cuando el inducido gira 30 revoluciones por segundo

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

Your target variable is δf, the magnitude of the difference in frequency between the waves emitted from the sonar device and the waves received by the device after reflecting off the whale. write an expression for δf in terms of the relevant frequencies using the subscript notation introduced above.

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
