The table lists information about four devices. A 4 column table with 4 rows. The first column is labeled device with entries W, X, Y, Z. The second column is labeled wire loops with entries 60, 40, 30, 20. The third column is labeled current in milliamps with entries 0. 0, 0. 2, 0. 1, 0. 1. The last column is labeled metal core with entries yes, yes, no, no. Which lists the devices in order from greatest magnetic field strength to weakest? W, X, Y, Z W, Z, Y, X X, Z, Y, W X, Y, Z, W.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.

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.
