By conservation of momentum,
Distance lighter fragment slide= 7*6.7=46.9m
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:
0.0786
Explanation:
zero after the decimal place is not a significant figure since it comes before the real integer "7".
"5 " in ten thousandth place is rounded off to "6" because the next digit is also another "5",
so we get the three sfg 0.0786
Answer:
Explanation:The rate of decrease of velocity is given with respect to displacement. As v approaches zero when s approaches 39, it can be written as
where c=19
when s=8 we have
hence a can be found by the chain rule
From the equation
the s in term of t can be found
Hence it can be seen that if s approaches 39 the t function becomes undefined hence s is never 39m
