Identify two technologies that can be used to find the locations of objects. Identify the type or types of waves each technology uses.

Coal contains energy. a. light b. kinetic c. chemical d. mechanical

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.

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.)
