Answer:
0.11694 kg/m³
Explanation:
T₁ = 0.0 °C = 273.15 K
ρ₁ = Density = 0.16 kg/m³
T₂ = 100.6 °C = 373.72 °C
PV = mRT
Realtion with density
P, m and R are constants, so
∴ New density of the gas is 0.11694 kg/m³

Answer:
t = 3.94 s
Explanation:
This can be modeled as a case of free fall motion. Because, the falcon is going down with acceleration, that is equal to acceleration due to gravity. To find the time taken by the falcon to intercept the pigeon, we will use second equation of motion for vertical direction:
where,
h = height = 76 m
vi = initial speed of falcon = 0 m/s
t = time required = ?
g = acceleration due to gravity = 9.81 m/s²
Therefore,
<u>t = 3.94 s</u>
