A string of 18 identical holiday tree lights is connected inseries to a 190V source. The string dissipates 62.0 W. One of thebul
PtichkaEL [24]

Answer:

549.9 ohms, 65.65 watts, the power went up

Explanation:  power P = V²/R

v= 190volts , P =62watts

from P =V²/R

62=190²/R

making R the subject

R×62= 190²

62R =36100

R=36100/62

R=586.25 ohms

Resistance of each lamp = 586.26/18 =32.3ohms

a) resistance of the light string now = 17×32.3 = 549.9 ohms

b) P=V²/R

where R=549.9ohms , P=?

P=190²/549.9

P=36100/549.9

P=65.65watts

Power dissipated has increased( went up )

>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.
