Los centros de dos pequeñas esferas metálicas con carga de 7.4×10−8 C están a 10 cm uno de otro. a) ¿Cuál es la fuerza eléctrica entre ellas? b) Una de las esferas se toca con otra idéntica neutra, ¿cuál es ahora la fuerza eléctrica si se mantienen a la misma distancia? La constante en la expresión de la ley de Coulomb es k=9.0×109 Nm2C2.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
