Answer:
B) Beth went back toward her origin.
Step-by-step explanation:
From 0 to 6, the graph increases. The dependent variable in this case is position and the independent variable is time; this means for this portion of the graph, as time increases the position increases as well.
From 6 to 10, the graph decreases. As time increases the position decreases. This means she goes back to her original position.
The angle would be 70 degrees because 180-110=70
<u>Answer</u>-
<em>The total capacitive reactance of the circuit is </em>442.10<em> Ω.</em>
<u>Solution-</u>
Three capacitors, a 12 mF, a 20 mF, and a 30 mF, are connected in series to a 60 Hz source.
The effective/equivalent capacitance of the circuit is,
When capacitors are joined in series, the total value of capacitance in the circuit is equal to the reciprocal of the sum of the reciprocals of capacitance of all the individual capacitors.
We know that,
Where,
= Capacitive Reactance (in Ω)
f = frequency (in Hz)
C = Capacitance (in F)
Here given,
= ??
f = 60 Hz
C = 6 mF = F
Putting the values in the formula,
Therefore, the total capacitive reactance of the circuit is 442.10 Ω.
If it's $2.70 now, the cost would be $4.45 in 1995.
