Answer:
Pressure of gas A = 544.324 kPa
Pressure of gas B = 2217.784 kPa
Explanation:
Data provided in the question:
Total volume of the cylinder, V = 5.55 L = 0.00555 m³ [1 m³ = 1000 L]
Moles on gas A, = 1.21 mol
Moles on gas A, = 4.93 mol
Temperature, T = 27.3°C = 27.3 + 273 = 300.3 K
Now,
Pressure =
here,
R is the ideal gas constant = 8.314 J/mol.K
Therefore,
Pressure of gas A =
=
= 544324.32 Pa
= 544.324 kPa
Pressure of gas B =
=
= 2217784.22 Pa
= 2217.784 kPa
Answer:
Radiant energy

Answer:
Explanation:
Since the surface is frictionless, momentum will be conserved. If the bullet of mass has an initial velocity and a final velocity and the block of mass has an initial velocity and a final velocity then the initial and final momentum of the system will be:
Since momentum is conserved, , which means:
We know that the block is brought to rest by the collision, which means and leaves us with:
which is the same as:
Considering the direction the bullet moves initially as the positive one, and writing in S.I., this gives us:
So kinetic energy of the bullet as it emerges from the block will be:
The answer is B. StructuralismThis school believes that the mind is divided into three basic elements, namely: sensations, feelings and images. This idea allows psychologist to study the interaction between the elements in order to create a conscious experienced. This will allow the person to associate the elements to one another and thus create a perception
