When the temperature is near [[$ 0 $]] ° C, the speed of sound (m/s) that travels through air can be calculated with the formula [[$ c = 330 + 0,6T $]], where T is the temperature in degrees Celsius.

a) When the speed of sound increases by [[$ 6 $]] m / s, by how many degrees does the temperature rise?



Answer: The temperature rises by °C when the speed of sound increases [[$ 6 $]] m/s.

b) When the temperature drops to [[$ 5 $]] ° C, what happens to the speed of sound?

Answer: As the temperature drops to [[$ 5 $]] ° C, the speed of sound increases decreases by m/s.

c) If a graph of speed is plotted as a function of temperature, then at what point does the graph intersect the y axis?

Answer: The graph intersects the y axis at m/s.
