Our federal government has three parts. They are the Executive, (President and about 5,000,000 workers) Legislative<span> (Senate and House of Representatives) and</span>Judicial<span> (Supreme Court and lower Courts). The President of the United States administers the Executive Branch of our government.</span>
<span>We can calculate the speed of sound with this formula:
v = 331 + 0.6T, where v is the velocity of the sound wave in units of m/s and T is the temperature measured in degrees Celsius.
When the temperature is 36°C, the velocity of the sound wave is:
v = 331 + (0.6)(36) = 331 + 21.6 = 352.6 m/s.
The correct answer is A. 352.6 m/s
(Please note that we do not use the unit Hz to measure the velocity of a sound wave. The unit Hz is used to measure frequency. We should use m/s to measure the velocity of a sound wave.)</span>
