Answer:
D. 2.5 Hz
Explanation:
Frequency = speed of wave / wavelength
= 335 /140 ( from graph)
= 2.4
Yes they are equivalent because 7x5=35 and 8x x 5=48x
Answer:
The current lags the potential difference by π/2 in an inductor
Explanation:
The potential difference leads to the current by . Alternate signals such as current and voltage -in this case- are periodic, this means that this signals are repeated at fixed spaces of time. Thus, In an inductor the current lags the potential difference by .
