Determine el valor de la potencia electrica que experimente un circuito cual se somete a 120 voltios emitidos por accion de las

Allisa [31]

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 =

QC In ideal flow, a liquid of density 850 kg / m³ moves from a horizontal tube of radius 1.00cm into a second horizontal tube of

kvv77 [185]

The volume flow rates for ∆P is 6.81m³/s .

<h3>What is pressure?</h3>

The amount of force applied on perpendicular to the surface of an object per unit area. The unit of it is pascal.

According to bernaulli's theorem theorem

P+1/2pV²+pgy = constant

where p fluid density

g is acceleration due to gravity, pressure at elevation,v is Velocity at elevation ,y is height of elevation.

As there are two tubes then the height of tube 1 is equal to height of tube two .

P1-P2=1/2p(Vd²-Vl²)

The flow rate of liquid is A1V1=A2V2 .

What is the study of kinematics based upon ?<br><br>thankyou ~

NikAS [45]

Kinematics is the study of the motion of a system of bodies without directly considering the forces or potential fields affecting the motion. In other words, kinematics examines how momentum and energy are shared among interacting bodies.
