Answer:
Capacitive reactance is 132.6 Ω.
Explanation:
It is given that,
Capacitance, 
Voltage source, V = 20 volt
Frequency of source, f = 60 Hz
We need to find the capacitive reactance. It is defined as the reactance for a capacitor. It is given by :



So, the capacitive reactance of the capacitor is 132.6 Ω. Hence, this is the required solution.
Answer:
72km
Explanation:
30 mins --> 30 x 60 s = 1800 s
Distance --> Speed x Time
= 40m/s x 1800s
= 72 000 m
= 72 km (1km is 1000m)
A. 100m because you add the 25m he swam east with the 75m he swam west.
