Answer:
D. 4000 km
Explanation:
f = Frequency of wave that is being transmitted = 76 Hz
= Wavelength of wave that is being transmitted
v = The velocity of electromagnetic waves through air = 
Velocity of a wave is given by

Hence, the approximate wavelength of the waves is 4000 km
103.9 hours, if you never stopped for any reason.
5 times that of initial pressure i.e 1625 kpa
Each station can detect how far away the epicenter was. So each station basically has a circle made of possible epicenters. When you have three, you narrow it down to one, final point.
Answer:false
Explanation:
Ohms law:
Potential difference (volts)=current(ampere)×resistance(ohms)
Coulombs is a unit for quantity of Charges and it is not in ohms law
