ANSWER:

3 seconds

STEP-BY-STEP EXPLANATION:

We have the following formula:

v=u+a\cdot t

Where, v is the final velocity that is equal to 4 m/s, u the initial velocity that is 10 m/s, a is the acceleration that would be equal to -2 m/s^2, we replace and calculate for t:

\begin{gathered} 4=10-2\cdot t \\ 2t=10-4 \\ t=\frac{6}{2} \\ t=3\text{ sec} \end{gathered}

STatiana [176]

Answer:

by doing rapid shallow breathing and pursed lip breathing  

Explanation:

Pressure with in the chest wall and the outside of the lungs remains negative because the intrapleural pressure is always lesser than the intra-alveolar pressure or atmospheric pressure. In general forced expiration leads to an increasing positive pressure in pleura. This happens because the pleura airway gets compressed and the size of airway reduces thereby forcing expiration.  

People who are able to resist airway can increase airflow by doing rapid shallow breathing and pursed lip breathing

If a bullet travels at 551.0 m/s, what is its speed in miles per hour?
77julia77 [94]
<span>First, convert meters into feet. One meter = 3.28 feet. Next, convert meters per second to feet per second. 551.0 m/s = 1,807.28 ft/sec. Now using the knowledge that 5280 ft = 1 mile and there are 3600 seconds in an hour; convert 1,807.28 ft/sec into miles per hour. The final answer to the question is 1,232.24 miles per hour.</span>
