What is convex mirror formula? 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors. What is the formula to calculate mirror? It is also known as a mirror formula…. u is the Object distance. v is the Image distance. f is the […]

Can gamma rays be stopped? The energy that is released as the atoms become stable is known as radiation. There are three types of radiation: alpha particles, beta particles and gamma rays. Beta particles can be blocked by a sheet of aluminum, but gamma rays require several inches of lead, concrete or steel to be […]

Can you trick an O2 sensor? You can “trick” the computer by putting in an 02 simulator which basicly just sends the computer an “all ok” voltage so that the computer thinks the converter is still there. What color is the signal wire on an O2 sensor? It’s usually the black one on a 4 […]

Why Maxwell equations are not invariant under the Galilean transformation? is not invariant under the Galilean transformations. Therefore the wave equation is not invariant under the Galilean transformations, for the form of the equation has changed because of the extra term on the left-hand side. The electromagnetic wave equation follows from Maxwell’s equations of electromagnetic […]

Does power equal force times velocity? Remember that power is equal to force times velocity (equation (2) above), and energy is power multiplied by time. This means all the solutions below will work: A power of 294 watts for one second. A power of 29.4 watts for ten seconds. What is average power formula? Use […]
