In physics, potential energy is the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. The unit for energy in the International System of Units is the joule (J). One joule can be defined as the work required to produce one newton of force, or one newton times one metre. Potential energy is the energy of an object. It is the energy by virtue of an object's position relative to other objects. Potential energy is associated with restoring forces such as a spring or the force of gravity. The action of stretching the spring or lifting the mass is performed by a force which works against the force field of the potential. The potential energy of an object is the energy it possesses due to its position relative to other objects. It is said to be stored in the field. For example, a book lying on a table has a large amount of potential energy (it is said to be at a high potential energy) relative to the ground, which has a much lower potential energy. The book will gain potential energy if it is lifted off the table and held above the ground. The same book has less potential energy when on the ground than it did while on the table. If the book is dropped from a height, it gains kinetic energy, but loses a larger amount of potential energy, as it is now at a lower potential energy than before it was dropped.

agent is given by a question. The relationship with compressors, change and volume changes given by Cushion 12.7. So that is the secretion returned inside the right box. Now we're given that he is single 0.1% off me. Not therefore in council fraction. This is equal to 0.1 over 100 times We're not. So the ratio between dehl be over find one over 100. Now we also need the utmost very pressure, which is a constant, and it's equal to tended by five times into the part five Newton for me. Now, now we use this, A question will 0.7. So from here we get an expression for Delta P in terms off they TV not and be. Now we can use this value this ratio and directly plug this value into this. A question on also the value off be that were given. I'm doing that. Figured the pressure chains to be nine times 24 7 energon bombmakers, girl. Now it's time to find the issue between Del P and P atmosphere. So we do that using the answer that we just found on the value of a most Merrick Christer and we get to the show to be 900 atmospheres
