I would like to be able to generate enough electricity to supply my home, and get off of the grid. I already have a home made wind generator powering a car alternetor, into car batteries going through an invertor for some things. I have 40 acres of land to work with, and the wind blows every day, but not consistantly. I would like some information that might further my indepenance with out huge expenses up front for set-up

What is the lethal dose of plutonium? Is that high or low for a toxic compound? How long is it retained in the liver? In bone?

We eat a lot of seafood that's imported from different countries. But most of them are shipped frozen already. I want to have some idea (like the technology [if any] used) on how live marine fish and other products are transported worldwide.

Thanks.

It seems that Jupiter gives off more energy than it receives from the sun as a result of fusion at its core and its structure is gaseous much more like the sun than the earth. Is Jupiter really a dwarf star in orbit around the sun as opposed to being a planet?

A crate is pulled by a force(parrallel to the incline) up a rough incline. The crate has initial speed of 1.49 m/s. The crate is pulled a diestance of 7.46 m on the incline by a 150 N force. The acceleration of gravity is 9.8 m/s^2 and the angle is 28 degrees. The friction coefficient is 0.27. What is the change in kinetic energy of the crate, answer in Joules. And what is the speed of the crate after it is pulled 7.46 m? answer in m/s.
Anyone know the answers and why?
