<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>

<h3>How to depict the information?</h3>

Ok so. What would you do if ur mom and dad said they ordered your x mas gifts online, buuuttt, that your gifts were not going to
vovangra [49]

Answer:

Well I wouldn’t worry about it. The item will come sooner or later and you probaly won’t use it as much, try to ignore the item and stop watching things and reviews of the item because being impatient for the item to come is just gonna make you think it’s coming slower. but late items are not as late as you think, even during this corona thing. Items that arriving from other countries should take about 1-2 weeks and if its in the same country, d_elivery should be 5-7 days Max. Even with corona, planes aren’t slowed down, they just cut the amount planes but not even by a quarter so plane‘s schedule should usually be on time and if delayed, it shouldn’t make you wait for another week, It should take about 2-3 days. So don’t trust the manufacturer if they
