Step-by-step explanation:
The speed of sound in air at 50°C can be calculated using the following formula:
v = 332 + 0.6T
where v is the speed of sound in m/s and T is the temperature in Celsius.
Substituting T = 50°C into the formula, we get:
v = 332 + 0.6(50)
v = 332 + 30
v = 362 m/s
Therefore, the speed of sound in air at 50°C is approximately 362 m/s.
Similarly, the speed of sound in air at 70°C can be calculated using the same formula:
v = 332 + 0.6T
where T = 70°C
Substituting T = 70°C into the formula, we get:
v = 332 + 0.6(70)
v = 332 + 42
v = 374 m/s
Therefore, the speed of sound in air at 70°C is approximately 374 m/s.
