Which situation would result in a decrease of 39.2 ) in the described object's gravitational potential energy?

Under normal temperature and pressure conditions, what type of rock could be formed from weathering in erosion of metamorphic rock

What property of an object determines its inertia?

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.)
