Answer:
Arrival times of P and S waves
Explanation:
Seismological recording station has a seismometer that senses that motion in the ground, a clock that records time and a data recorded.
The distance between beginning of the first P wave and the first S wave will give you the time the waves are apart.This time value will be used to find the distance between the seismograph and the epicenter of earthquake and you mark it.This is corresponding distance in km to the time in seconds obtained before.You then find the amplitude of the strongest wave and mark it on the right side of chart.Amplitude is the height on paper of the strongest wave.Using a ruler join the amplitude point and the point where you marked the distance to epicenter.This line will cross the magnitude chart at a point which represents the magnitude of the Earthquake.
Answer:
0.000133046 V
Explanation:
B = Magnetic field = 7 T
t = Time = 20 s
d = Diameter = 2.2 cm
r = Radius =
A = Area =
Induced emf is given by
The induced emf is 0.000133046 V
Answer:
600 J
Explanation:
The formula to find the kinetic energy of an object is
- m = mass in kg
- V = velocity in m/s
- KE is measured in Joules just as all other forms of energy.
Now, let's plug in the variables we're given and simplify.
Thus, the answer is 600 Joules.
The "pitch" of a sound is the impression your brain forms
that corresponds to the frequency of the sound wave.
When the frequency is high, your brain says "high pitch".
When the frequency is low, your brain says "low pitch".
