The wavelength of light emitted by a particular laser is 488 nm. This laser light illuminates two slits that are 58.0 µm apart. (a) What is the angular separation between the n = 2 and n = −2 maxima? ° (b) If a screen is placed 1.70 m from the slits, what is the distance between these two maxima? Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. cm (c) If you want these two maxima to be 1.00 cm apart, how far from the slits do you need to place the screen? cm

How does an observation about an object differ from an inference about that object

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)

The amount of work done is determined by 2 factors. describe an example of work (using the scientific definition) list the 2 factors that determine the amount of work done.
