Hi, i wonder if it is possible to assemble a homemade "refrigerator" to achieve temperatures lower than -100 C ? Any ideas?

I have no idea where to stat on this question. A magnetic field is perpendicular to a 0.040 m 0.080 m rectangular coil of wire that has 110 turns. In a time of 0.040 s, an average emf of magnitude 2.0 V is induced in the coil. What is the magnitude of the change in the magnetic field? Can...

In a home heat pump, heat is absorbed from the Earth by a fluid circulating in buried pipes and delivered to the home interior. Suppose that the heat pump is 40% as efficient as a Carnot refrigerator. If the ground surrounding the pipes is at 5`C and the interior temperature of the house is kept...

I run a bingo game at the nearby nursing home. The other day a lady covered all of the 25 [5x5] spaces on her card with 17 numbers yet to call. If there are 75 numbers to call at the beginning of the game, and the numbers are distributed in columns randomly among 1-15 under "B," 16-30 under...

Hi, I am from the uk and very interested in home power generation. I am aware that there is a system that you can install in the home which will 'sell' excess power back to the grid if for example you are running a wind turbine which produces more electricity than your home requires...

I am having problems with this question: An m = 2.12 kg box rests on a plank that is inclined at an angle of q = 64.5° above the horizontal. The upper end of the box is attached to a spring with a force constant of 15.2 N/m. If the coefficient of static friction between the box and the...

On in the afternoon Saturday of Thanksgiving we let our cat Mies out. After about 3 hrs, he hadn't returned and I began to get worried, as he is usually never gone for more than an hr or two before he wants to be let back in. I went out and called for him but he was nowhere around. I started to...

this is my first time in here. Thought I'd look around, see the place moonbear calls home. I like what you've done with the place, but I got to tell you the thread titled, "Sticky fun with molecular biologists." Wasn't exactly what I thought it would be.
