Blue and red lasers (with wavelengths 475 nm and 633 nm, respectively) are shone through a diffraction grating towards a wall 4.2 m away. Each laser produces a pattern of dots on the wall and the dots from both patterns are very close together in three locations, each separated by 3.1 m.

Use the table to answer question 22 23 and 24.

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.

A-4.60 μc charge is moving at a constant speed of 6.80×105 m/s in the +x−direction relative to a reference frame. at the instant when the point charge is at the origin, what is the magnetic-field vector it produces at the following points.
