Dc-power supply problem

Reference no: EM13667561

A new material is found to be superconducting below 94 K. How much resistance will a 93 mm long sample of this material have if it is at a temperature of 84.6 K while linked to a 4.5 V DC-power supply?

What is the ratio of the radii : A proton and an electron have the same kinetic energy and travel in parallel paths as they enter a region of constant magnetic field. They each begin to move in circular paths. What is the ratio of the radii?

White light is incident from air onto a triangular prism : White light is incident from air onto a triangular prism at a 45 degree angle by respect to the normal. It refracts at the prism then again at the air as it exits the prism. If the prism has an index of refraction of 1.49 for red light and 1.52 for v..

Discover magnitude of the induced current in the coil : An N-turn square coil with side l and resistance R is pulled to right at constant speed v in the positive x-direction in the presence of a uniform magnetic field B acting perpendicular to the coil. At time t = 0, the right side of the coil is at the ..

Doppler effect for light is exactly same because for sound : The Doppler Effect for light is exactly the same because it is for sound. Hubble discovered that things further away from us were moving away from us faster than things close to us. In fact, there is almost a linear relationship among distance and re..
