Two very long parallel wires are 1cm apart and carry currents of 10A in the same direction. The material surrounding the wires has r = 1. Determine the force 0.5m section of one of the wires. Do the wires attract or repel one another?

The two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656 nm(red) and 486 nm (blue). light from a hydrogen lamp illuminates a diffraction grating with 520lines/mm , and the light is observed on a screen 1.5m behind the grating. part a what is the distance between the first-order red and blue fringes? express your answer to two significant figures and include the appropriate units.

Avalue that describes how heavy an object is and is related to the force of gravity is
