The answer for this would be A. since power is Joules/seconds and energy is rated in Joules
Interactúan dos objetos cargados dependiendo de la carga domínate en el objeto, ya que cargas iguales se repelen y cargas opuestas se atraen. ... Al frotar un cuerpo cargado con otro objeto de carga neutra, este se cargara pero adquiriendo la carga opuesta al objeto cargado inicialmente.
Answer:
a. 2.5 X 10^-1
Explanation:
First of all we shall calculate the resistance of the bulb of 75W , 240 V .
power = V² /R , V is potential and R is resistance
75 = 240²/ R
R = 240²/ 75
= 768 ohm .
Now this bulb is used with 120 V
current = 120 / 768
= .15625 A
power = V X I
potential x current
= 120 x .15625
= 18.75 W.
comparing it with 75 W
the ratio
18.75 / 75
= 2.5 x 10⁻¹.
