Answer: It is D (The average kinetic energy of the particles)
Explanation:
I don’t know what you mean by “give me a reason to live as well” but I think you should live because even though it is hard sometimes there will always be someone that cares about you and would never know what life would be like without you even if you may not have found that person yet they are somewhere in the world and you just need you keep going and find that special person! Hope this helps!
Answer:
His displacement is 260 – 169 = 91 km
His distance traveled is (260 – 134) + ( 169 – 134 ) = 161 km
Explanation:
Answer:
Using the log combination rules to reduce the famous Sakur-Tetrode equation, The change in entropy is given as:
∆S = NK*ln(V"V$/V").
Where V"V$ is final Volume (Vf) after constraint's removal,
V" is Initial Volume (Vi) before constraint's removal.
Temperature (T) is constant, Internal Energy, U is constant, N and K have their usual notations
Explanation:
Given in the question, the container is an adiabatic container.
For an adiabatic contain, it does not permit heat to the environment due to its stiff walls. This implies that the Internal Energy, U is kept constant(Q = U). The temperature is also constant (Isothermal). Thus, the famous Sakur-Tetrode equation will reduce to ∆S = NK* In(Vf/Vi).
Vf is the volume after the constraint is removed(Vf = V"V$). Vi is the volume occupied before the constraint is removed (Vi = V")
The correct answer is D. Let us analyze briefly each concept in order to justify this answer.
A) Chemical changes are changes in which the nature of the material changes; for example when paper burns. Cutting paper is not a chemical change because the substance of the paper remains the same. When changes are very drastic like the start of the Universe or in radioactive materials, there are nuclear reactions which change the substance and are another category of processes.
B) Cosmic Redshift is an aftermath of the dilation of the Universe. Galaxies that are moving away from us give off a lower frequency light, hence their light is becoming "more red". This is not the cause of the production of light elements.
C) Cosmic Background Radiation is a direct aftermath of the Big Bang and it is predicted by the model. Because we have that at the start, all matter was concentrated together, it was very dense and it radiated. As the Universe dilated, this radiation became less intense, but it is still detectable.
D) Nucleosynthesis is the term we are looking for. It literally means: composition of nuclei. It refers to how protons and neutrons combined in the first 3 minutes to form nuclei of light elements
Answer:
one of the characteristics of a mammal is their several hollow bones another is their three chambered heart and the last is highly developed nervous system
Explanation:
the reason i picked those three is because not all mammals live their life on land and also mammals font have internal fertillization when they are done they take care of their babies and when they grow up they live their own life
