Answer:
14.488 amperes
Step-by-step explanation:
The amplitude I of the current is given by
where
= amplitude of the energy source E(t).
Z = Total impedance.
The amplitude of the energy source is 120, the maximum value of E(t)
The total impedance is given by
where
<em> R= Resistance </em>
<em>L = Inductance </em>
<em>C = Capacitance </em>
<em>w = Angular frequency </em>
= inductive reactance
= capacitive reactance
As E(t) = 120sin(12t), the angular frequency w=12
So
and
Finally
Answer:
14.69 seconds
Step-by-step explanation:
The weighted mean is used to calculate the mean of numbers which don't have the same "weight" or statistical relevance. In this case, that relevance is based on the sample size of each group from which the mean reaction times were obtained.
For all three samples, the weighted mean is obtaining by multiplying each one of the mean reaction times by its <em>n value, </em>adding them, and dividing that result by the sum of all n values.
