The rate is 9.8m/sec

heart mediater, it causes rapid increase in heart rate, causes stroke, heart attack etc.
Increasing the temperature the dissolving rate increase.
Gravity causes falling objects to accelerate.
During exercise, the body requires more oxygen to fuel the muscles, which leads to an increase in breathing rate (respiratory rate) and heart rate to deliver more oxygenated blood to the muscles. This helps to meet the increased energy demands of the body during physical activity. Regular exercise can improve cardiovascular and respiratory system efficiency, resulting in lower resting heart rate and more controlled breathing.
9.8 meters per second squared.
Increased Heart Rate
because when your doing the exercises it causes the heart rate to increse.
