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

i do.

explanation:

i want to explore the wonders of the universe and find out if there really is life out there. i think the universe is beautiful.

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
