Best ResponseYou've already chosen the best response.1You have an equation using the equation t=k/p Your first step is figure out what k is, to do that, replace t and p with a pair of numbers that "go together" They give you one pair of numbers, the first line in your table. Can you find k?

Best ResponseYou've already chosen the best response.1yeah, but what would be the pairs for the others? like how do I figure it out? :/

Best ResponseYou've already chosen the best response.1the first line says depth pressure time 0ft 1atm 60min they give you a p (1 atm) and time (60 min) use this info in t=k/p to find k

Best ResponseYou've already chosen the best response.1so 60=k/1 ..i would times both sides by 1?

phi

Best ResponseYou've already chosen the best response.1you could, but anything divided by 1 is itself, so just rewrite k/1 as k you get k= 60

phi

Best ResponseYou've already chosen the best response.1so make a note, your equation is t= 60/p

phi

Best ResponseYou've already chosen the best response.1now to use this equation, you need to find the pressure at each depth in the table. Activity 1 gives an equation for how to find the pressure at a depth. Can you use it to fill in the pressure column ?

Best ResponseYou've already chosen the best response.1the d=33+1 equation? :S

phi

Best ResponseYou've already chosen the best response.1yes, but get the details right. What is the equation for finding P ?

Best ResponseYou've already chosen the best response.1p=d/33+1? i don't know :(

phi

Best ResponseYou've already chosen the best response.1They say The pressure P (atm) varies with depthd( ft) according to the equation P= d/33 + 1 You have to be able to read complicated sentences. It's not math, but reading. but to continue, for each depth in your table, you use this equation to find the pressure at that depth. for example, for d=0 ft (depth is zero feet) , replace d with 0 in the equation P= 0/33 + 1 = 1 P is 1 at depth= 0 feet can you fill in the rest of your depths with the pressure at that depth ?

Best ResponseYou've already chosen the best response.1yes! what about the time?

phi
 one year ago
Best ResponseYou've already chosen the best response.1one step at a time. Once you have the pressures filled in, you go back to the equation we figured out already, t = 60/p to find the time (in minutes)

Best ResponseYou've already chosen the best response.1okay, will do :D!

Best ResponseYou've already chosen the best response.1p=33/33+1=2 t=60/2=30 hopefully I got this right? if I got that right then I'm sure the rest are :D

Best ResponseYou've already chosen the best response.1looks good. btw, you will get fractions (or decimals) for depth=20,
