1 AnswerEngineering7 years agoWhich uses less electricity to heat a glass of water? One burner on a 4 burner stove top, or a coffeemaker?
Say it takes 7 mins to heat the water to the same temperature on a stove as opposed to 3.5 mins with a coffee maker. Calculations would be awesome too! I'm excluding heating it in a microwave because of the experiments I've seen on youtube when watering plants with microwaved water.

3 AnswersCell Phones & Plans9 years agoCough and Throat home or simple OTC remedies?
My dad always had this thing about clearing his throat all the freaking time with like a shrill for as long as I can remember. It freaking drove me nuts as a teen. Now when I go to visit, he still insists on clearing his throat, and spitting with like a dry and hollow cough. Lately I noticed its getting pretty bad, and more consistant, but he insists on doing it all the time. He's never smoked, drank and plays golf regularly. Is it out of habit he does it, or is there really something wrong with the guy, and are there any home remedies that can help him out?
Thanks so much

4 AnswersMathematics9 years agoHow did you quit smoking?
I have been a smoker for about ten years now, 8 of which I have chosen to strictly smoke all natural tobacco using cotton only filters and rice papers. I thought that if I eliminated the excess chemicals in smoking I could quit easier, but it has taken this long to no avail. I don't get too amped when I don't smoke, but I have a lot of trouble keeping my mind off of smoking when I don't. Any advice and stories would really be helpful!!

Additional Details
Easy 10 points for most helpful explanation. I don't even want the answer, I just wanna know how to get the limits.
11 minutes ago
Sorry, the k term is supposed to be (1-t^2)
This is calculus III stuff. I have to find the arc length, I know what the antiderivative is gonna be, I just need the find the limits of integration to get a finite value.
Thanks
