Mechanical or Electromagnetic
Answer:
Part a)
When rotated about the mid point

Part b)
When rotated about its one end

Explanation:
As we know that the angular acceleration of the rod is rate of change in angular speed
so we will have

When rotated about the mid point



now torque is given as


Part b)
When rotated about its one end



now torque is given as


They have more energy than radio waves.
Answer:
La potencia de la bombilla es de 1056 W.
Explanation:
La potencia de la bombilla se puede calcular usando la siguiente ecuación:

En donde:
P: es la potencia
I: es la corriente = 2,4 A
V: es la diferencia de potencial = 440 V
Entonces, la potencia es:

Por lo tanto, la potencia de la bombilla es de 1056 W.
