Blood vessels are the body part that is included in the circulatory system.
Answer: -1038.8 kJ
Explanation:
From the question, we can see that PV^n = constant. And as such, we can deduce that it is a polytropic process. Thus, we can use the polytropic work equation to calculate the needed work input.
from the question we were given
Mass of nitrogen, m = 7kg
initial temperature, T1 = 250k
Final temperature, T2 = 450k
Polytropic index, n = 1.4
Specific gas constant, R = 0.2968kJ/kgK
W = [p2 * v2 - p1 * v1] / 1 - n
W = [m * R * T2 - T1] / 1 - n
W = 7*0.2968*(450 - 250)] / 1 - 1.4
W = [7*0.2968*200] / -0.4
W = 415.52 / -0.4
W = -1038.8 kJ

Answer:
A
Explanation:
most mammals are viviparous instead of oviparous. oviparous means laying eggs
Your question asks which is an example of an atom that has no change, or charge.
Your answer would be C). 2 protons, 2 electrons, and 1 neutron
These atoms would be known as a neutral atom.
In order for an atom to be neutral, it must have the same amount of protons and electrons.
We know that Protons are positive
We also know that Electrons are negative
In order for the atom to be neutral, they must have an equal amount of protons and neutrons to "cancel out"
In answer choice C, you would see that there are 2 protons and 2 electrons.
2- 0 = 0, in which allows this atom to be neutral.
Therefore, answer choice C. 2 protons, 2 electrons, and 1 neutron would be your answer.
