The energy of the wave decreases gradually
bazaltina [42]3 years ago
3 0

Answer:

Explanation:

  The energy of the wave its determined by the mass of the fuid of the wave and the speed. The amount of motion equation P= m.v

  So according to the impulse and amount of motion theorem (ΔP= mvₙ- mv₀).

  If the wave is acted upon by an external dumping force, the wave its going to decrease his energy because the reduction of the speed and the mass.

Ayuda por favor !
Mrrafil [7]

La respuesta es 3 ohmios

Resistencia total = (1/12 + 1/4) ⁻¹

= (1/3) ⁻¹

= 3 ohmios

Por ejemplo, dos resistencias, R1 y R2 están en serie, la resistencia combinada es R1 + R2.

Cuando se conecta en paralelo, la resistencia total es el recíproco de (1 / R1 + 1 / R2)

En este caso las resistencias están en paralelo

Espero que esto ayude, que tengas un día bendecido!
