Which set of coordinates most accurately locates the boundary between the Jurassic mudstones and the Cretaceous shales and sandstones? Location 1: 39.701200 degree, -105.201430 degree
Location 2: 39.701072 degree, -105.201621 degree
Location 3: 39.700935 degree, -105.201790 degree
Location 4: 39.700575 degree, -105.202275 degree

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

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.
