Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

11. At time t;, the kinetic energy of a particle is 30.0 J and the potential energy of the system to

only conservative forces act on the particle, what are the potential energy and the total energy of
the system at time t;?

A student struggled with his first midterm exam and is slightly angry. For this reason he drops a 10 kg object on the good teacher from a height of 5 m. When seeing the object fall to the ground, the teacher asks the logical question: How much will the internal energy of the box have increased after hitting the ground? If the specific heat of the box is cp = 3 kJ / kg.K How much will the temperature of the box have increased?

a javelin thrower releases their 600-g javelin 2.0 m above the ground traveling at an angle of 30∘∘ above the horizontal. top-rated javelin throwers do throw at about a 30∘∘ angle, not the 45∘∘ you might have expected, because the biomechanics of the arm allow them to throw the javelin much faster at 30∘∘ than they would be able to at 45^\circ$. in this throw, the javelin hits the ground 70 m away. Calculate the initial speed of the throw.

A fixed mass of gas undergoes changes of pressure and volume as shown below. V When the gas is taken from state P to state R by stages PQ and QR, 8 kJ of heat are absorbed by it and 3 kJ of work are done by it. When the same resultant change is achieved by stages PS and SR, 1 kJ of work is done by the gas. In this case which of the following represents the heat transfer? Select one: 8 kJ of heat are absorbed b. 4 kJ of heat are rejected 12 kJ of heat are rejected O d. 10 kJ of heat are absorbed
INTRODUCTION: In thermodynamics, energy can be neither created nor destroyed (1st law): it is either converted to usable work or lost as waste heat. The second law of thermodynamics states that the total entropy (disorder) of a system will never decrease over time; that is, systems can only be at constant entropy or have increasing entropy. This may be restated by saying that there is an upper limit to the efficiency of the conversion of heat to work, as in a heat engine. From these principles of thermodynamics, it is clear that there is an upper limit to how efficient power generation can be at most power plants. Many power plants, including those fueled by fossil fuels, nuclear sources, geothermal sources, biomass, and solar thermal, operate by generating a source of heat (burning fossil fuels, reacting nuclear materials, using the sun’s rays, etc.), using this heat source to heat water to steam, and passing this steam through a turbine. When the turbine spins, power is generated.…
