8) one direction is, ironically, not traveling in one direction (i know they aren't current i'm more of a big
time rush guy myself). their car moves at a constant velocity of 4 m/s in the +x direction. in the +y
direction, they start from rest but accelerate up at 1.5 m/s2. determine the car's position horizontally
(in the x-direction) after they have traveled 21 m in the y-direction. show your work! hint: time is one
variable can you find in y which can also be used in x? (16 points)
how do i do this?

Astudent is given an assignment to demonstrate diffraction. he takes a photograph of a straw in a glass of water. the straw appears bent at the water level. which best describes this example? a) this is a good example of diffraction. b) this is an example of dispersion and not diffraction. c) this is an example of refraction and not diffraction. d) this is an example of reflection and not diffraction.

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ
