Jeff is part of a trekking team. as he climbs a hill, he drops his water bottle, which has a mass of 0.25 kilograms.
the bottle slides down the hill and is moving at a velocity of 14 meters/second the instant it hits the ground. the vertical height from where jeff dropped the bottle is meters. ignore friction, and use , pe = m × g × h, and g = 9.8 m/s2.

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.

When using the scientist method, which step comes last?

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.)
