Abigail is a sixth grade student who has never been in trouble before, but she just got caught scratching graffiti onto a bench at the playground. She doesn't
know why she did something that she knew was wrong, but you have an idea!
Her Risk and Reward Workers may be the problem.
1. Write a letter to abigal that shows what happens with the boss brain, reward workers, and risk workers during middle and high school.
—Checklist:
It must be at least five sentences.
I used complete sentences as well as proper grammar and spelling.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Light from a sodium lamp passes through a diffraction grating that has 1000 slits per millimeter. the interference pattern is viewed on a screen 1.000 m behind the grating. the first (m = 1) two bright yellow fringes that are visible are 0.7288 m and 0.7300 m from the central maximum. what are the wavelengths of these two fringes?

What is the increase in density of a medium due to wave travel?
