Answer:
The west axis component of walk is, A = 5 miles
The east axis component of walk is, B = 8 miles
Explanation:
Given data,
The displacement of hiker south of west, R = 9.4 miles
The angle formed south of west, Ф = 60°
The vector components along,
the west axis is
A = R cosФ
A = 9.4 x cos 60
A = 4.7 miles
A = 5 miles
The west axis component of walk is, A = 5 miles
the south axis is
B = R sinФ
B = 9.4 sin 60
B = 8.14 miles
B = 8 miles
The east axis component of walk is, B = 8 miles
Answer:
521.8 V
Explanation:
The RMS value of the voltage of an AC signal is given by
where
is the peak voltage, which corresponds to the amplitude of the AC waveform
In this problem, we know the RMS voltage
Therefore, we can re-arrange the previous equation to find the peak voltage (the amplitude of the waveform):
Answer:
C
