Answer:
The answer is below
Explanation:
Given that the volume (V) = 0.4 m³, temperature difference (ΔT) = 270 K - 350 K = -80 K, pressure (P) = 60 kPa = 60000 Pa, R = 8.314 J/molK
Since we have constant volume, we can use the final state parameters to calculate the number of moles using the ideal gas law:
Given that the molar heat capacity at constant volume () = 28.0 J/(mol K), the heat absorbed (Q) is:
Q ≈ -24 kJ
Answer:
θ = 61.3°
She must swim at an angle of 61.3°
Explanation:
Given;
Width of river = 100 m
Alicia speed in still water = 2.5m/s
Current of river = 1.2m/s
The angle for her to achieve her goal can be derived by the summation of velocity in the direction of the current.
Her speed in the opposite direction of the current must be able to neutralise the speed of the current;
2.5cosθ - 1.2 = 0
2.5cosθ = 1.2
cosθ = 1.2/2.5
θ = cosinverse(1.2/2.5)
θ = 61.3°
As per Newton's law of cooling we know that
in 5 hours the body temperature becomes 79.6 from 84.4
while the surrounding temperature is given as 68 degree F
now from above formula
now let say the person died "t" time ago
now we will have
so he died at approx 5 Am in morning
They are, in fact termed: Body Waves.
