Dielectric Constant Of Water

Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.

Electrostatic Potential and Capacitance

An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particle…

Certain types of particle detectors can be used to reconstruct the tracks left by unstable, fast-moving sub-atomic particles. Assume that a track with a length of L=2.97 mm in the laboratory frame of reference has been observed. Further assume that you determined from other detector data that the particle moved at a speed of L=0.910 ⚫ c, also in the laboratory frame of reference. c denotes the speed of light in vacuum. What proper lifetime would you determine for this particle from the data given? T= 4.0 S

While cruising down University Boulevard you are stopped by a cop who states that you ran a red traffic light. Because you don't want to pay the stiff fine, you are attempting a physics defense. You claim that due to the relativistic Doppler effect, the red color of the light λ=616 nm appeared green '=531 nm to you. The cop makes a quick calculation of his own and rejects your defense. How fast, in terms of your speed u divided by the speed of light in vacuum c, would you have to drive to justify your claim? Note that the speed u is taken to be a positive quantity. U 4.0 C
