Asample of aluminum metal absorbs 11.2 j of heat, upon which the temperature of the sample increases from 23.2 °c to 30.5 °c. since the specific heat capacity of aluminum is 0.90 j/g-k, the mass of the sample is g.

Which of these has some mechanical energy? a. an atom b. heat inside earth c. a book on a shelf d. the fire from a lit match

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)

The release of energy by the nucleus of atom as a result of nuclear fission is radiant energy true false
