Homework Help v1.3

I need help again....
I don't quite understand the flow rate thing in science.

I did a experiment on it and i was wondering if you guys can help clear it up for me.

I don't get how the flow rate for 20-24oC is higher than the flow rate for 45-50oC, and the time for 20-24oC is longer than the 45-50oC one too.

[batman555]

Flow rate is the measure of mass or volume of your substance over a time interval.

From your table, your flow rate is higher for the higher temperatures. I speculate that it is because of the higher energy in the higher temperatures that help the molecules move faster. Or move the same distance in a shorter amount of time.

[Banana_Alchemist]

So i'm confused now...

which temperature has the highest flow rate?
if the 20-24oC has teh highest flow rate then how come the time is longer than the 45-50oC time?

[RagingVortex]

Frankly, I think the Flow Rate and Time needs to be explained. What units is the rate in? Time for what to happen?

[Banana_Alchemist]

I personally dunno cause i just copied that chart from a friend cause i missed most of the science class

[RagingVortex]

Then I think your friend wrote something down wrong.

Assuming that the correction for the middle column as 12°C is supposed to be there, the time goes down as the temperature goes up. (to be expected) Yet the flow rate goes down, then back up, something that doesn't correspond to the times recorded. Somehow I think that middle column's flow rate is incorrect.

[Banana_Alchemist]

Yep he wrote in something wrong, i just asked him about it, after reading your post, and you were right, the middle column's flow rate was supposed to be 0.58.

I kinda cleared it all up, thanks

I could only find a few summaries/counter essays. Alot of the sites ask for money first for the essays.

I need some help... and i don't know how many people can help me... but I would appreciate all the help I can get.

I need anything on derivatives of sine functions... pretty much on calculus level, maybe just pre-calc I don't know. I have to describe the behavior of the gradient of the function f(x) = sin X on the given domain. I know how to graph this, however I am confused what it means with describing the behaviour of the gradient, on the given domain? :S hehe was a while ago since I did this... Then I have to do a conjecture of the derived function...

Thnx! grateful for all the help I will get...

^its asking u to find the slope funtio
ie. f'(x)
which i believe is cosx

Yeah... I know that the drivative of sin is cos... but I am asking what they mean with describing the behaviour of the function on the given domain? and what is a conjecture for a function? :S

sorry if I was confusing or not specific enough...

and by the way... anyone that has a good website about this stuff?

[Denny Crane]

just say is the function increasing or decreasing in the domain range
max and min values, or any local maxima/minima in the area

Thats it? wow... to me it sounded a lot more complicated than that... thnx!

Me again..

Can anyone tell me the relationship between mass and weight?, cause i don't think there is a relationship cause there two different things, and teh textbook ask me to state teh relationship, so i'm kinda confused.

[heinzbitte]

W=MG

Weight= Mass x Acceration due to gravity (around 9.81)

I'm not positve though.

[Banana_Alchemist]

I was trying to find the Relationship between the two, sry if the eariler post wasn't really clear

The weight of a body is the magnitude of the net force required to prevent a body from free falling; weight= mass x acceleration. Remember, mass and weight are two different things; weight depends on the value of gravity but a body's mass (an intrinsic property) does not change.

[batman555]

force = mass * acceleration

weight = mass * gravity

Weight is a measure of how hard gravity is pulling on the mass. Mass remains constant, but if gravity changes, then so does the weight. This explains why you'd weigh differently on the moon.

Does this answer your question?

[Banana_Alchemist]

yea pretty much thanks again

1250= 100t + 16t squared the basic formula is D=rt+16t squared where r stands for rate and t stands for time and D stands for distance I need to find out t HELP PLEZ!!!!!!!!!!!!!
