Answer:
volume of air breath = 495.75 mL per min
Explanation:
given data
oxygen required = 2.4 × 10² mL / Min = 240 mL
inhaled air = 20 %
exhaled air = 16 %
to find out
volume of air per breath
solution
we know here that breathes 12 time every minute
and we consider here air breath = y per min
we know oxygen remain in body = 20 % - 16 % = 4%
and required 12 time air breath
so air required = 240 / 12 = 19.83 mL
so oxygen breath equation will be
y × 4% = 19.83
y = 19.83 / 0.04
y = 495.75
so volume of air breath = 495.75 mL per min
Answer:
The answer is B complimentary
Explanation:
If I'm right you use the formula E=mgh
so it would become E=8×1.6×2
Your answer is 25.6J (joules) :)
It'll last 20 hours. If it travels 110 miles in one hours, 110 times 20 equals 2,200.
