Answer:
Ethnomethodology theory
Explanation:
Take note of the fact that we are told Kevin worries that the police will stop and question him even though he has not done anything wrong.
This statement shows us that Kevin already understood his society from past experiences, and thus he tries to avoid social interactions with particular member of his society (the police) who may be show discrimination towards him.
Answer:
120V
Explanation:
Given parameters:
Current = 6A
Resistance = 20Ω
Unknown:
Voltage = ?
Solution:
According to ohms law;
V = IR
Where V is the voltage
I is the current
R is the resistance
Now, insert the parameters and solve;
V = 6 x 20 = 120V
When resistors are connected in series, they act like
a single resistor whose resistance is their sum.
100 ohms and 400 ohms, connected in series, look like
a single resistor of 500 ohms.
Current = (voltage) / (resistance)
= (60 volts) / (500 ohms) = 0.12 A.

Current is measured by connecting a meter in series
with an energized component. In other words, a break
is made in the circuit, the meter is connected in the break,
and the current to be measured literally flows through the meter.</span>
