Answer:
The temperature in degrees Celsius is <em>-48°C </em>.
Step-by-step explanation:
The given equation is:
v = 20√[t + 273]
Therefore, rearranging we get:
(v / 20)² = t + 273
t = (v / 20)² - 273
but the speed of sound, v, is equal to 300 m/s
Therefore,
t = (300 / 20)² - 273
<em>t = -48°C</em>
<em></em>
Therefore, the temperature in degrees Celsius is <em>-48°C </em>.
