my focus was shaking and it was the motor mounts, got them replaced and the shaking stopped.... as far as the car just stopping, its gotta be a completely separate issue..... i dont think the bad mounts should cause that. 8 out of 8 people think this is helpful.
Beta radiation, consisting of electrons or positrons, is halted by an aluminum plate. Gamma radiation is damped by lead. Beta particles are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei, such as potassium-40. The beta particles emitted are a form of ionizing radiation also known as beta rays. The production of beta particles is termed beta decay. They are designated by the Greek letter beta (Î²). There are two forms of beta decay, Î² â and Î² + , which respectively give rise to the electron and the positron.
The velocity of beta particles and the calculation of the kinetic energy of beta particles. The mass of a beta particle (electron) = 9.11 x 10-31 kg, typical beta particle speed is 90% of the speed of light (0.9 c). This calculation ignores relativistic effects (relativity theory) whereby the mass of a particle dramatically increases, the nearer its velocity is to that of light. (Note that the mass of a beta particle with a speed of 0.9 c is 2.09 x 10-30 kg).
