Particles q1, q2, and q3 are in a straight line. Particles q1 = -1.60 x 10-19 C, q2 = +1.60 x 10-19 C,
and q3 = -1.60 x 10-19 C. Particles q1 and q2 are
separated by 0.001 m. Particles q2 and q3 are
separated by 0.001 m.
What is the net force on q2?
Remember: Negative forces (-F) will point Left
Positive forces (+F) will point Right

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
