Science TN Ready Practice-Set 3

A company designed an electromagnetic tool that removes dents from metal plates. The dented metal is placed between 2 magnets. A current is then supplied to the electromagnets. The attraction between the 2 magnets forces the dented metal plate back into place. How can engineers test to see if their design is successful?

• compare the cost of operating the tools to other dent removal tools

• compare the shape of the treated metal with the original shape of the metal

• compare the type of metal plates treated by the company to those of other companies

• compare the energy requirements of two similar dent removal tools

Cold ocean currents are most likely to be located at deeper ocean depths than warm water currents because

• winds push the cold water down

• ocean tides force cold water downward

• cold water is more dense and sinks

• cold water has less salt to help it freeze and sink
