Could you show the derivation of elastic strain energy per unit volume?
U= vol metric integral1/2(stress* strain)dxdydz
Beta oxidation of these molecules converts them into acetyl-coa which can then enter the Krebs cycle for energy derivation these are?
answer is fatty acids (I had the exact same question in my Ap Test)
What is the key reason behind radioactive decay?
E = mC squared The mass energy equation (Einstein' derivation) applied to sub atomic particles which shed protons to attain a more stable electrovalence leads to the energy associated with that bond being released Alpha particles ,beta particles or gamma particles Americium-241--->neptunium -237 + Alpha particle (Helium Nucleus)
Why is there half the number mv2 in the equation of kinetic energy?
The formula as usually written is............. KE =1/2 mass * velocity squared KE = 1/2mV^2 but you can rewrite this as.......... KE = mV^2/2 which answers your question by saying........ mass and velocity squared are divided by 2 to get kinetic energy
Does kinetic energy actually increase the speed of an object?
Gaining kinetic energy 'E' amounts to saying that the momentum of an object increases. E = p^2 / 2m where p is momentum and m is mass. (Momentum is just mass times speed.) So, to increase the speed the kinetic energy has to change. In other words, if you set the kinetic energy to any value you like and keep it constant, there won't be a speed up. What is the change in kinetic energy? You can just as well ask what is the change in momentum. Physicists have chosen the latter question and call the change in momentum 'the force'. F = dp / dt where F is force and d/dt means derivation with respect to time. It is the pushing force acting on objects that makes them gain speed. Kinetic energy is usually something that you calculate at the end when you have found out what the forces in your problem are and what the momentum is as a function of time.
What is the derivation of temperature?
Temperature(s) is/are not derived, they are arbitarily decided scales. They are indirect measures of atomic/molecular vibrational energy.
Derivation of magnetic quantum number from schrodinger wave equation?

How is kinetic energy of an object determined?
The kinetic energy of anything is determined by the mass and velocity of the substance. This is represented in the equation: KE=(1/2)mv2
Why integration and derivation is important in chemical engineering?
integration and derrivation have maney applications in chemical engineering .they are used to make calculions in heat transfer ,mass transfer,mass balance,energy balance ,fluid mechanic,process controle which are important topics in chemical engineering.

Mathematical derivation of law of conservation of energy?
The mathematical derivation of te Law of Conservation of Energy is setting the First derivative of the energy to zero. The derivative being zero means there is no change (conservation) of energy.There are two problems in physics : first the formulation of energy is incorrect, energy is a quaternion quantity consisting of a scalar (potential) energy and a vector energy,E= Scalar + Vector = Es + Ev.Typical scalar energies are the gravitational scalar energy Es= -GmM/r and the electrical scalar energy Es= -qQzc/4pi r.The vector energy is generally Ev= mcV where V is the vector motion and c is the speed of light.The second problem in Physics is that the Derivative is also a quaternion,X= d/dr + Id/dx + jd/dy + kd/dz = d/dr + Del = d/cdt + Del where the scalar dr=cdtGiven the Quaternion nature of Physics, the mathematical derivation of the Law of Conservation of Energy is:0=XE= (dEs/dr - Del.Ev) + (dEv/dr + Del Es + Del xEv)For this first derivative to be zero there is another condition 0=DelxEv. This is required because the vector DelxEv is perpendicular to the other two vectors. If DelxEv is not zero the sum of the three vectors will not be zero. With 0= DelxEv, the other vectors are collinear and opposite to reduce to zero.Therefore, the mathematical and physics Law of Conservation of Energy is :0 = XE = (dEs/dr - Del.Ev) + (dEv/dr + Del Es)this quaternion equation resolves to a scalar equation and a vector equation:0 = (dEs/dr - Del.Ev) and0 = (dEv/dr + Del Es)dEs/dr=Del.Ev also called the Continuity Equation (dEs/cdt = Del.Ev)dEv/dr = -Del Es or dEv/cdt = -Del Es

Why does Eo equal to mc2 (rest energy equals to rest mass x speed of light x speed of light)?
For the complete derivation of the formula, read a text on Special Relativity. Here, I just want to note that when you multiply a mass times the square of a speed, you will get, precisely, units of energy. Also, it means there is a certain equivalence between mass and energy. For example, if you add heat to a substance, there will be a small increase in its mass as well. Greetings, I never liked that expression. Mechanical energy is mv2/2. See, there's that "divided by two" sitting in the expression. Why not with light? I've heard all the usual reasons, and I don't like them. Cheers,
Range of a bow and arrow?
When a bow is pulled back with the arrow in place, elastic potential energy is stored in the bow and thus arrow. When released, all that potential energy is converted into kinetic energy. EPE=KE. Since you know the "pounds" of the bow, the weight of the arrow, and how high the arrow is from the ground you can calculate the an arrows range assuming it is parallel to the ground. Derivation: KE= .5 X Mass X Velocity^2 Distance= Velocity X Time Time the Arrow is in Flight= [( vertical distance x 2)/ (32 ft/sec^s)]^(1/2)
