Responder: 480 vatios
Explicación:
La potencia en un circuito eléctrico am puede expresarse como el producto si la corriente y el voltaje en el circuito.
Potencia = corriente × voltaje
Corriente dada = 4 amperios
Voltaje = 120 voltios
Potencia gastada en el circuito = 4 × 120
Potencia gastada en el circuito =
480 vatios
You haven't said whether the two resistors are connected
in series or in parallel. It makes a difference.
-- If they are in series, then their combined effective resistance is
(3 + 2) = 5 ohms.
Current in the circuit is (voltage)/(resistance) = 1.5/5 = 0.3 Amp.
-- If they are in parallel, then their combined effective resistance is
(3 x 2) / (3 + 2) = (6/5) = 1.2 ohms.
Current in the circuit is (voltage)/(resistance) = 1.5/1.2 = 1.25 Amp.
Is this a multiple choice question?
If not, well then the answer is that the volcano sort of sinks into the ground. Like it sort of subducts.
Hope this helped!!!:)

Answer:
The recoil velocity is 0.354 m/s.
Explanation:
Given that,
Mass of hunter = 70 kg
Mass of bullet = 42 g = 0.042 kg
Speed of bullet = 590 m/s
We need to calculate the recoil speed of hunter
Using conservation of momentum
Where,
= mass of hunter
= mass of bullet
u = initial velocity
v = recoil velocity
Put the value in the equation
Hence, The recoil velocity is 0.354 m/s.
