For a Person at Rest,the Velocity V (In Liters Per $v = 0.85 \sin \left( \frac { \pi t } { 3 } \right)$

question 30

Multiple Choice

For a person at rest,the velocity v (in liters per second) of airflow during a respiratory cycle (the time from the beginning of one breath to the beginning of the next) is given by​ $v = 0.85 \sin \left( \frac { \pi t } { 3 } \right)$ , ​
Where t is the time (in seconds) .
(Inhalation occurs when v > 0,and exhalation occurs when v < 0. )
​
Find the time for one full respiratory cycle.
​

• A)7 sec
• B)9 sec
• C)3 sec
• D)8 sec
• E)6 sec
