Consider a car moving leftward on the x-axis. when it is at x = 100 m and moving at a speed of 20 m/s, it begins to slow down uniformly until it stops after travelling for 4.0 seconds. a. draw a motion diagram to represent this part of the motion. b. draw two graphs, x vs. t, and vx vs. t. indicate how the given information is used to draw the graphs. c. how far did it travel in coming to a stop from when it first started to slow down?

Natural forces that can alter ecosystems include seasons and climate changes. t or f

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.

What is the measurement of how fast an object moves relative to a reference point?
