ANSWER:
Cardiac output(CO) in L/min = stroke volume(SV) X Heart rate(HR)
Therefore,
CO= 100 x 75= 7500 ml/min
CO= 7.5 L/min
EXPLANATION:
CARDIAC OUTPUT is the volume of blood, pumped by the heart, that goes through the systemic circulation every minute. It is determined by the stroke volume and heart rate.
STROKE VOLUME is the volume of blood ejected from the ventricles of the heart in each contraction.
HEART RATE is the number of times the heart beats in a minute.
D because if you are trying to reduce the carbon footprint then using less coal or oil based energy would be best. plus using the solar panels will help because all you have to rely on is the sun and your own power bank for energy. there for leaving less of a carbon footprint.
Heat stroke is the most serious heat-related illness. It occurs when the body becomes unable to control its temperature: the body's temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down. Body temperature may rise to 106°F or higher within 10 to 15 minutes.
