Answer:
0.00583 seconds
Explanation:
Distance from mic 1 to origin = 3 m
Distance from mic 2 to origin = 5 m
Speed of sound = 343 m/s
Time taken by mic 1
Time difference = t₂ - t₁ = 0.14577-0.008746 = 0.00583 s
∴ Difference in time taken by the speaker is 0.00583 s
Answer:
a)V= 0.0827 m³
b)P=181.11 x 10² N/m²
Explanation:
Given that
m = 81.5 kg
Density ,ρ = 985 kg/m³
As we know that
Mass = Volume x Density
81.5 = V x 985
V= 0.0827 m³
The force exerted by weight = m g
F= m g= 81.5 x 10 = 815 N ( Take ,g= 10 m/s²)
Area ,A= 4.5 x 10⁻² m²
The Pressure P
P=181.11 x 10² N/m²
