In Active Example 3-29 you calculated that you would have to work six weeks to earn enough money to buy a 1082.49 television. You would be working five shifts of four hours each at 9.25/hr. But, alas, when you received your first pay check, you found that exactly 23 of your earnings had been withheld for social security, federal and state income taxes, and workers compensation insurance. Taking these into account, how many weeks will it take to earn the 1082.49?

In our first lab experiment we will be identifying metals by measuring theirdensities and comparing them to known values. Here at NJIT we have a very large and generouslaboratory materials budget, so all sorts of exotic and extremely valuable metals will be providedfor the experiment. Using the values listed below, determine the identity of the metal samples.If the density value determined is not amongst the values below then one of those cheapRutgers samples crept into our stock of metal samples and you should answer “unknown metal”.Note: volume measurements are not very exact. If your density determination is off by 0.1 or0.2 from the known value, that’s probably good enough for an identity. Table in image 4a. You weigh your sample and determine it weighs 71.8 grams. You put the sample into 15.6 mL ofwater and the total volume rises to 22.4 ml. What metal do you have?4b. You weigh your sample and determine it weighs 56.3 grams. You put the sample into 28.9 mL ofwater and the total…
Is it faster to 1) adjust the liquid level to exactly hit a graduated cylindermeasurement mark or, 2) to estimate the last digit of precision in reading thevolume? Is one more accurate than the other?
I am slightly confused on how to do this. I think I figured it out but I just want to compare data and take notes on what I have done incorrectly.
If 1.5 x 1022 carbon atoms were placed side-by-side in a line, how long would that line be (in feet) if the radius ofa carbon atom is 77 pm? Set up and solve a single step dimensional analysis problem that includes all necessaryfactors.
