By using the potential energy rule E=mgh=71(10)(2)=1420 note i took the value of gravity 10
A change in potential energy means that there is work
Work=potential energy
Work=1420J

A circuit consists of a resistance R, and an inductance L in parallel connected, which is in series with a second resistance R2.
Allisa [31]

Answer:

The impedance of the inductor is ω L:

This is in parallel wth R giving a resistance of the parallel combination:

1 / Rp = 1 / ω L + 1 / R

Rp = (ω L * R) / (ω L + R)      for the impedance of the parallel combination

Total resistance (impedance) Rt = Rp + R2 = Z

One can use the term impedance to show that the resulting current is not in phase with the resulting voltage    

phase angle φ -    cos φ  = ω L / Rt

V = I Z        shows the relation of voltage and urrent

un cilindro uniforme empujado por una tabla desde una posicion inicial mostrada en la figura, rueda hacia delante por el suelo,
Andreyy89

Answer:

L/2.

Explanation:

Hola.

En este caso, dado que el hombre empuja el cilindro desde el punto L=0 y hasta la mitad de la longitud entre el hombre y el cilindro, es claro que el cilindro se desplaza un L/2 más de la distancia inicial entre el hombre y el cilindro, de este modo, inferimos que el hombre también ha caminado L/2.

¡Saludos!
