Answer:
C) 200 m/s
Explanation:
The sound travels a total distance of 360 m in 0.03 minutes.
v = (360 m) / (0.03 min × 60 s/min)
v = 200 m/s
Answer:
Frequency, f = 7.57 Hz
Explanation:
It is given that,
Capacitance, 
Capacitive reactance, 
We need to find the frequency. The capacitive reactance of the capacitor is given by :
f is the frequency
f = 7.57 Hz
Hence, this is the required solution.
Answer:Electric Current!
Explanation: Electric current ;)
<span>The word is "pitch", which is exactly that: How "high" or "low" a sound is.</span>
Using the Debroglies equation,energy can be found,as 1.9773*10*-9
then, energy* wave length= hc
c is the speed of light and is the planks constant.
wave length =1.006*10*-16 m
