Answer:
Explanation:
Volume ,V = 3 L
Initial temperature ,T₁ = 273 K
Initial pressure ,P₁ = 105 kPa
Final temperature ,T₂ = 381 K
Lets take final pressure =P₂
We know that ,If the volume of the gas is constant ,then we can say that
Now by putting the values in the above equation we get
Therefore the final pressure will be 146.53 kPa.
Answer:
From smallest ratio to the largest ratio:
Coasting Universe - Critical Universe - Recollapsing Universe(From left to right)
Explanation:
The coasting universe is one that expands at a constant rate given by the Hubble constant throughout all of cosmic time. It has a ratio of actual density to critical density that is less than 1
The critical universe is one that is at balance with no expansion .I.e. the actual density and the critical density are equal, which makes the ratio of actual density to critical density to be equal to 1
Recollapsing Universe: The expansion of the universe reverses in the future and the universe eventually recollapses. The recollapsing universe has the ratio of the actual density to the critical density to be greater than 1

Answer:
Explanation:
Conservation of momentum
Initial momentum is zero as both gun and bullet are motionless in the frame of reference before firing.
0 = 0.012(1500.0) + 4.0v
v = - 4.5 m/s
Must be a rail gun as the fastest powder driven bullets are moving at roughly half the speed described.
