A chemical reaction that releases heat is exothermic, so that means that the chemical reactions in our body are releasing heat as aerobic respiration is inefficient. Therefore why are humans called endothermic? Does this mean that cold blooded organisms are exothermic?

In traveling to the Moon, astronauts aboard the Apollo spacecraft put themselves into a slow rotation to distribute the Sun's energy evenly. At tje start of their trip, they accelerated from no rotation to 1.0 revolution per minute during a 12-min time interval. The space-craft can be thought of as a cylinder with a diameter of 8.5m. Determine (A) the angular acceleration, and (B) the radial and tangential components of the linear acceleration of a point on the skin of the ship 5.0 min after it started this acceleration

A friend of mine told me that she has ruined remotes and telephones, because she gives off too much electricity. She said she had been hooked up to a volt meter and it said she was giving off between 300 - 400 millivolts. She also says she's been able to charge rechargeable batteries. I find this very interesting, and was wondering if there was other info about this somewhere. It's almost like having super powers (very weak super powers, but powers nonetheless).
