Explanation: Those factors are mass and distance. I hope this helps!
Answer:
2100 kPa
Explanation:
The temperature is constant, so the only variables are pressure and volume.
We can use Boyle’s Law.
p₁V₁ = p₂V₂ Divide both sides of the equation by V₂
p₂ = p₁ × V₁/V₂
p₁ = 485 kPa; V₁ = 648 mL
p₂ = ?; V₂ = 0.15 L = 150 mL Calculate p₂
p₂ = 485 × 648/150
p₂ = 2100 kPa
(4) 615 m
Explanation:
From the table we see that the speed of sound in air at 20 °C is 343 m/s. Knowing this we devise the following reasoning:
if the sound travel through the air 343 meters in 1 second
then the sound travel through the air X meters in 2.38 seconds
X = (2.38 × 343) / 1 = 816.35 meters
