The paradox of a charge in a gravitational field is an apparent physical paradox in the context of general relativity. A charged particle at rest in a gravitational field, such as on the surface of the Earth, must be supported by a force to prevent it from falling. According to the equivalence principle, it should be indistinguishable from a ...
v. t. e. In physics, the observer effect is the disturbance of an observed system by the act of observation. [ 1][ 2] This is often the result of utilising instruments that, by necessity, alter the state of what they measure in some manner. A common example is checking the pressure in an automobile tire, which causes some of the air to escape ...
Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. [ 1] In physics, energy is a quantity that provides the capacity to perform work or moving (e.g. lifting an object) or provides heat. In addition to being converted, according to the law of conservation of energy, energy is ...
Scientists. v. t. e. Electrostatic induction, also known as "electrostatic influence" or simply "influence" in Europe and Latin America, is a redistribution of electric charge in an object that is caused by the influence of nearby charges. [ 1] In the presence of a charged body, an insulated conductor develops a positive charge on one end and a ...

Proportional counter. The proportional counter is a type of gaseous ionization detector device used to measure particles of ionizing radiation. The key feature is its ability to measure the energy of incident radiation, by producing a detector output pulse that is proportional to the radiation energy absorbed by the detector due to an ionizing ...
Two pylons are planned to be erected on Dyfan and Carys Walters' farm [BBC] "This plan isn’t going to benefit anyone here in the Towy Valley," Dyfan says. "It’s to take energy to the grid ...
Energy level splitting. In quantum physics, energy level splitting or a split in an energy level of a quantum system occurs when a perturbation changes the system. The perturbation changes the corresponding Hamiltonian and the outcome is change in eigenvalues; several distinct energy levels emerge in place of the former degenerate (multi- state ...
