The kinematics and geometry can locate the point where the earthquake occurs: Point of interception of the three circles
The earthquakes occur due to a sudden movement of two tectonic plates, this movement produces longitudinal and transverse waves with different speeds, called S and P waves. The speed of the waves is constant, so we can use the uniform kinematic movement relationship
v = d / t
Where v is the speed of the wave, d is the distance and t is the time.
The speed of the two types of waves is known, they depend on the material and type of wave varies between 4 and 7 km / S, the time is measured in the seismometers, for which we can calculate the distance.
For a seismometer, the calculated distance corresponds to a circle, so to locate the epicenter of the earthquake we must have a minimum of three earthquakes, the point of intersection of the circles is the place of occurrence of the event, see the attachment for a diagram of the process.
In conclusion, with kinematics and geometry we can locate where the earthquake occurs: Point of interception of the three circles

Answer:
Lower Heart Rate
Athletes' heart rates tend to be lower than heart rates of non-athletes. A low resting heart rate is generally a sign of good cardiovascular fitness and efficiency. A well-trained athlete may have a normal resting heart rate of only 40 beats per minute, compared with the average heart rate that ranges from 60 to 100 beats a minute.
Lower Disease Risk
Athletic types may have better overall health and be less apt to develop certain diseases. Regular exercise boosts your immune system and lowers the risk of serious health conditions such as cancer and heart disease. Physical activity can also reduce the risk of type 2 diabetes and osteoporosis while helping to manage cholesterol levels and blood pressure. You gain about two hours of additional life expectancy for each hour of regular exercise, according to the American Heart Association.
Psychological Effects
Athletes may have better mental clarity and focus than non-athletes. Exercise increases the flow of oxygen, which has a direct impact on brain function, explains the American Heart Association. Exercise can help improve your memory and reduce negative feelings, such as anger, tension, anxiety and depression.
A comprehensive study of the academic performance of North Carolina high school student-athletes in North Carolina over a three-year period attests to the positive psychological effects of athletic capabilities. Researchers discovered obvious differences between athletes and non-athletes. The study of nearly 127,000 high school students found dropout rates were lower and grade point averages were higher in students who participated in sports. The study was led by Dr. Roger Whitley in collaboration with the North Carolina High School Athletic Association.
Motivated by Excellence
Athletes, especially competitive athletes, have high ambitions. It's a trait that allows them to persevere through setbacks and failures and to come out the other side stronger. Athletes are highly motivated individuals who set their sights on a prize and are single-minded in their pursuit of excellence. They are propelled by passion to become the best they can be and the benefits of that inner drive are a higher level of self-esteem and confidence.

Answer:
Whenever the pH of a solution is 7, it will be a neutral solution. Such a solution will have no effect on any litmus solution or any other indicator. pH of an Acidic Solution: All the acidic solutions have a pH of less than 7.
