Homework Statement In a Young's double-slit experiment, a set of parallel slits with a separation of 0.102 mm is illuminated by light having a wavelength of 580 nm and the interference pattern observed on a screen 4.50 m from the slits. (a) What is the difference in path lengths from the two...

Homework Statement A container is filled to a depth of 20.0 cm with water. On top of the water floats a 29.0-cm-thick layer of oil with specific gravity 0.800. What is the absolute pressure at the bottom of the container? (Answer in Pa) Homework Equations P= ρgh+ P(atmospheric) The...

I actually tried putting it in Pa instead and I got it right thank you so much for the tip! :)

I do not know the correct answer, I only have 5 tries and this is my last try to get it right :frown: and I can proceed to part b whenever I want but for it to be right I need to have the exact right answer for part a so it would help a ton if you could help point out the exact answer which I...

but then why are my calculations wrong according to my webassign answer key :confused:

Homework Statement (a) Calculate the absolute pressure at the bottom of a fresh-water lake at a depth of 22.5 m. Assume the density of the water is 1.00x10^3 kg/m3 and the air above is at a pressure of 101.3 kPa. (b) What force is exerted by the water on the window of an underwater vehicle at...

I'm not quite sure how to simplify that part it would help if you would tell me how :c

Homework Statement A 25g object moving to the right at 20cm/s overtakes and collides elastically with a 10g object moving in the same direction at 15 cm/s. Find the velocity of each object after the collision Homework Equations Ʃp=Ʃp' v1+v1'=v2+v2' The Attempt at a Solution First...

Hey guys I figured it out and identified the forms of energy as PEs initial=PEgfinal/ mgdsin30=1/2kx^2 and rearranged the formula for d and plugged in numbers, I believe I got the right answer now thanks for the help <:

Homework Statement A .500 kg block rests on a horizontal, frictionless surface as in the figure below. The block is pressed back against a spring having a constant of k=625 N/m, compressing the spring by 10cm to point A. Then the block is released. a) Find the maximum distance d the block...
