which of the following is an example of an insulation -
....ANSWER.....✓✓a piece of paper
a block of wax
a block of glass
all of the above are examples
which of the following statements concerning charge is
most accurate - ....ANSWER.....✓✓the total charge
present in the system and surroundings is constant in
any process
Two charged particles both have positive net charges.
They are near each other and released from rest. Which
of the following statements best describes the
interaction of the particles ? - ....ANSWER.....✓✓The
particles will repel. As they get further apart, the

amounts of protons and electrons
Two 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? - ....ANSWER.....✓✓When a positively charged
rod moves near the left of the block, it attracts or pulls
negative charge of the block.
a 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? - ....ANSWER.....✓✓The ballon caused the
ceiling to polarize, which created a net attracting force
between the polarized ceiling and the balloon
an 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 -
....ANSWER.....✓✓separate further
