The Moons appearance as seen frorm Earth changes during the 28-day lunar cycle. You can see how the
changes happen by looking at the Sun-Earth-Moon systerm.
This diagram shows the relative positions of the Sun,
Earth, and the Moon at each point in the cycle.

Which staterment best describes how the phase of the Moon changes from a
full moon to a new moon?

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.

Answer///(d) atoms contain small,negatively charged particles;

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

Ithink the answer for this is: an electromagnet is a magnet  with a soft metal core.
