Movement that is like a t 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. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another 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 = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

Astudent uses universal ph paper to find the ph of three solutions . solution a has a ph of 5 solution b has a ph of 11 and solution c has a ph of 7 identify which solution is acidic which solution is neutral and which solution is basic

This has nothing to do with school. i wrote a poem to my crush, who i'm asking out soon. tell me if it's cheesy, or cute. "roses are red, violets are blue no love story sounds right if it doesn't include you. dance with me all night, gaze into my eyes i'll hand you my heart, as well as my pride. when i hear your name, my heart goes insane. your all that i want, all that i need promise me you'll stay with me. here it is the final line, jasmine hill will you be mine?
