Aparticle is represented by the following wave function: ψ(x) = 0 x < −l/2 = c(2x/l + 1) − l/2 < x < 0 = c(−2x/l + 1) 0 < x < +l/2 = 0 x > +l/2 (a) use the normalization condition to find c. (b) evaluate the probability to find the particle in an interval of width 0.010l at x = l/4 (that is, between x = 0.245l and x = 0.255l. (no integral is necessary for this calculation.) (c) evaluate the probability to find the particle between x = 0 and x = +l/4. (d) find the average value of x and the rms value of x: xrms = (x2)av.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

the word that best describes martin luther king jr.'s tone in the video is dignified

martin luther king, jr. was a social activist and baptist minister who played a key role in the american civil rights movement from the mid-1950s until his assassination in 1968. the video shows his manner and attitude having or showing a composed or serious manner that is worthy of respect so dignified is the correct answer

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
