A 3 μf capacitor is connected to a 6 v battery. what is the charge on each plate of the capacitor?
Lapatulllka [165]
C = 3 uf = 3 × 10^(-6) f
v = 6volts
Q = C.v
 = <span>3 × 10^(-6) </span>× 6
 = 18 × 10^(-6)
 = 1.8 = 10^(-5)

&gt;En cual de las siguientes situaciones la fuerza neta sobre el cuerpo es cero?
ExtremeBDS [4]
La respuesta es "Un avion que vuela al norte con rapidez constante y altitud constante".

Para que la fuerza neta sea 0, la aceleracion debe ser 0, para esto la velocidad debe ser constante.  

Para que la velocidad sea constante el objecto debe estar moviendo con rapidez (magnitud de la velocidad) constante y sin cambiar direccion; ya que la velocidad es un vector asi es que depende en magnitud y direccion.

En las demas opciones la magnitud de la velocidad (rapidez) cambia y/o la direccion.

During one cycle, a refrigerator removes 500 J from a cold reservoir and discharges 800 J to its hot reservoir. (a) What is its
Paraphin [41]

Answer:

a)COP = 1.67

b) W = 300 J

Explanation:

given,

refrigerator removes = 500 J from a cold reservoir

discharge = 800 J to its hot reservoir

a) COP = \dfrac{Q}{w}      

   COP = \dfrac{500}{800-500}

   COP = 1.67                        

b) heat per cycle exhausted to the

     W + 500 = 800                        

     W = 800- 500                        

      W = 300 J
