I was watching Kim Possible and I started wondering if that naked molerat really exists. Then I googled it and found out that it's a real animal specie. But is disgusting. It seems to be inside out. Here the link for those who wanna check it out: http://en.wikipedia.org/wiki/Image:Nacktmull.jpg

Is there any animal uglier than that thing?

x^2 + 5x
------------ <- division line
x^2 - 25

how do u do that...i did (a+b) * (a-b) at the bottom becuz it's perfect squares but after that im stuck.

2y^3 - 12y^2 + 2y
----------------------
y^2 - 6y + 1

im completely stuck there. these questions are on a sheet that asks us to use the formula ax^2 + bx +c

PS: ^ <- this sing means to the power of....y^2 means Y squared

A sample of lauric acid was heated above its melting point in a test tube and then cooled in a bath of water until it solidified. The termperature of the acid was measured as a function of time

Then they show a temp-time graph the starts up around 62 C and drops to 46 C and remains at a constant temp for the rest of the graph

1. what is the physical meaning of the flat region on the graph?
is it just that the temperature of the acid at the time is constant and the acid is changing state?

2. Use the graph to estimate the melting point.

Would it just be the 46 C where the graph starts going constant?

3. Is heat being absorbed or released as it solidifies?

I put released since it says it is cooled in a bath of water...meaning the heat goes to the surroundings.

Can you just tell me if thats correct

If I were to keep track of a star's movement in the east and another star in the west, once a week at relatively the same time, how many degrees would the star appear to move? Also do they appear to be higher or lower in the sky?

Can you lift your weight using a pulley and rope, or would you just be lifting your body off the ground because the load is heavier than you, like a pull up.

I ran a 12V 1700mA battery recharger off a 12V 500mA voltage adaptor, and the adaptor died. Why? And how close do the mA ratings need to be for this not to happen?
