Before you get ready to go diving, you really want to eat a snow cone. you know there is a small food stand on the other side of the railroad tracks near the beach. as you carefully step over the tracks (making sure to look both ways you notice interlocking joints between some of the tracks. what are these joints called? what purpose do they serve? describe thermal expansion and why these joints are necessary.

How is the gravitational force related to the distance between two objects?

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

Which two particles are found in the center of an atom
