Answer: 248 Newton
Explanation:
force = rate of change of momentum
change of velocity
= 4 + 4 = 8 m/s
rate of change of momentum = mass per second x change of velocity
= 31 kg/s x 8 m/s
= 248 kg m/s^2 or Newtons
<u>Answer:</u>
False, Four seismometer statitons are no required to find the earthquake's epicenter.
<u>Explanation:</u>
The least number of seismometer stations sufficient for finding the epicenter of earthquake is three. Epicenter is point on earth's crust from where the seismic rupture gets originated. Using the distances to the epicenter from atleast three seismometers the epicenter of earthquake can be determined. This distance is used as the radius and 3 circles are drawn. The point at which the 3 circles intersect is called as epicenter of the earthquake. With one seismometer station, we can determine only the distance to the epicenter. With two seismometer station, measurements are ambiguous. Using more than three seismometer stations produces redundant information. Hence three seismometer is sufficient to determine the epicenter of earthquake.
False.
