question

Greta passed a comb through her hair several times. She then placed the comb next to a stream of water flowing from a faucet. Greta observed the stream of water bend toward the comb. How did passing a comb through her hair allow the comb to bend the stream of water?

choices

  • by making the comb more absorbent
  • by giving the comb an electrical charge
  • by increasing the thermal energy of the comb
  • by breaking some of the chemical bonds in the comb
