Students want to make a scale model of the Earth and Moon system that shows correctly-scaled sizes and distances. Here are some guidelines they have to follow. It has to be shown in the classroom, and the classroom is 51 square meters in area.
It has to be easily moved around since orbital motion and rotations will be shown.
It cannot cause damage if it is dropped.
All the students in the class should be able to see it from their desks.

Four different students came up with different designs. The designs and characteristics are shown in the table below.

Which design best satisfies the criteria and constraints of this Earth-Moon model?
A.
design 1
B.
design 3
C.
design 2
D.
design 4

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
