Deztany,
The heat capacity of ice is about 0.5 cal g-1 oC-1 . The heat required to change the temperature of an object is
heat (in cal) = (mass of object in g) x (temperature change of object in oC) x (heat capacity of object in cal g-1
oC-1 )
You do the math!...

Jason,
As I understand it, making a perfume doesn't really involve chemistry. You have to decide what "top note" (the first odor you smell, is the most volatile component usually), "middle note" (the odor after the top note evaporates off), and "bottom note"...

Sorry, Mark, not so.
Well let's see.
This is an equation; the (not necessarily integer) value on the left must equal the (not necessarily integer) value on the right. You are not ONLY concerned with the constant values on the right and left, because it's the total values that must match...

Don't start eating -- the answer is infinite, as far as you have stated the problem. It's not an interesting situation as framed anyway -- if you can only eat a specified number of items, you obviously maximize your calories by eating only gum drops. On
the other hand, if your sister, who weighs...

Matt,
Look at the dimensions of your concrete slab. What is length, width, and height here? Unless I'm very much mistaken, the thickness (height) had better be the 150mm dimension! OK, you're trying to frame the edges of the slab. That will be the perimeter
of the rectangle 6.0m x 2.5m. You...

Cacita,
You might want to look up "Munsell Color" or "Color Wheel" or "Color Space".
Any sample of light (for example, the light reflected from an object) has both a detailed composition (measurable instrumentally, and expressed per one of several systems, such...

Gable,
There's a few things you haven't indicated in your question. (One assumes you mean 0.75 inch, though you didn't say so.) What is the material of the sheathing pipe? Even if PVC, it is available in various wall thicknesses for various uses. One assumes
you only need a minimal covering...

Fernando,
When confronting a series such as this, usually you start by trying to make a pattern by the differences between successive terms. Thus 3, 9, 4, 12, 7, becomes +6, -5, +8, -5. The problem from this point lies in the unfortunate fact that an infinite number
of patterns...

Draw your circle edge and a tangent, a radius (R1) to the tangent point (T), and another radius (R2) to a point 64" along the tangent line (Point A). Then add a chord through T and the intersection of R2 and the circle (Point B). Bisect the angle formed
by R1 and R2, with the half-angle...

Ooh, what a poorly worded question! But if each person on a team (not just you!) can get 1, 2, or three points, does that help? Not really, if you take "ways" to mean things like who gets points, and in what order. But if nobody cares about that (did you
ever see a team where nobody...

Ali,
I predict that Amy and Sam are going to have trouble meeting back up -- they don't seem to have exchanged sufficient information!

Cody,
In problems of this sort, you need to start by considering how you calculate probabilities and how you combine them. For each individual cage, the probability distribution is determined by the combinations you could pick and their individual probabilities
of being selected. Then, the...

Kirubel,
It's a little difficult to be sure of the problem, when you're made such a mess of the typing. Why don't you learn to proofread and correct what you type? It's a definite "skill for success"!
Your title implies that the mean incomes for black and white populations were...

Jim.
This statement of the problem is confusing; is the goal the drawing of at least 2 brown socks, or of only 2 brown socks? It really matters; the former lets you draw, for example, 2 brown socks, then 2 of any color, and then multiply for the combinations,
whereas the latter requires you...

You would use the comma; you are refining and restating the phrase immediately preceding. -- It might be more apt to compare the Tao to a construct (the order of the Universe, or how the Universe *is*), rather than to a mechanism (how the Universe *works*),
however. Just sayin'!

Maybe just a bit more explanation would help. The rate law (without catalyst) assumes that the substances are reacting with each other only, in whatever state they may be (you may have noticed that usually only gases enter into rate laws; that's because
the effective concentration of liquids...

Lisa,
Wyzant isn't intended to answer your physics problem sets -- 5 problems at a time is spamming. It's to get you some spot help, past difficulties of conceptualizing what you have to do.
I'll help you with this one, though, and perhaps you can apply the type of thinking to the other...

Greg,
I suggest the following. You need to figure all the forces on the car doing the 95 km hr-1 loop, but you already know that that will depend on the angle of banking of the road.
So how do you figure the angle of banking? It's the angle that results in NO skidding tendency for the 80 km...

Joey,
Calm down! This kind of word problem is usually easy to solve (unless you haven't been given enough information to find a solution, in which case you may need to make some assumptions and then figure a reasonable answer).
The problem you're having, is that word problems are rather...

Dear Char,
It's more than a little hard to follow what the exact problem is that you're trying to solve! But, assuming that you really do mean a stain, and that the stain results from the impact of a spherical drop of liquid, you could make the probably grossly erroneous
assumption that the...
