atom is accurate? - ✔✔✔✔-neutrally charged atoms contain equal amounts of
protons and electronsANSTwo identical metal blocks are in contact side-by-side. A
positively charged rod moves near the left block. Which of the following most
accurately shows the resulting distribution of charge throughout the metal
blocks? - ✔✔✔✔-When a positively charged rod moves near the left of the block,
it attracts or pulls negative charge of the block.ANSa positively charged plastic
balloon filled with air will stick to a neutrally charged nonmetal ceiling. Which of
the following is the most likely explanation for this behavior? - ✔✔✔✔-The ballon
caused the ceiling to polarize, which created a net attracting force between the
polarized ceiling and the balloonANSan electroscope is a device that has small
gold foil strips suspended from a metal rod. If the electroscope is negatively
charged, the foil strips will repel and separate from each other. If you bring a
negatively charged rod near the top of a negatively charged electroscope, the foil
strips will - ✔✔✔✔-separate furtherANSWhich of the following is an accurate
example of charging by induction - ✔✔✔✔-a student brings a charged rod near a
block of metal. The student taps the block of metal with a hand and then
removed the charged rodANSTwo charged particles each with a net charge of-q
are a distance r apart. The electric force F is measured The distance between the
particles then doubles to 2r and the amount of charge on both charges doubles to
-2q. Relative to the original force, what is the new electric force. - ✔✔✔✔-
