Suppose there is a 1.1 F drop in temperature for ever thousand feet than an airplane climbs into the sky. If the temperature on the ground is. 45.2 F what will the temperature be when the plane reaches an altitude of 4,000ft

Volume of cylinder with a radius of 8cm and height of 25 cm

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?

Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.
