Select the correct answer. Henry is an economist and wants to understand the relationship between inflation and consumer spending habits. For his research, he needs
the Consumer Price Index for 2014 and the inflation rate. Based on the prices of goods given, what will he find to be the CPI and inflation rate for
2014? Assume that a consumer's basket for three consecutive years consists of the following
Number of Apples
Number of Oranges
Year
Price of an Apple
Price of an Orange

During physical science, ms. greene challenged her students to produce an energy transformation. james and jill wrapped a 4-inch nail with a coil of fifty turns of wire. they connected one end of the coil to one terminal of a knife switch. they connected the other terminal of the knife switch to the battery. finally, they connected the end of the coil to the other terminal of the battery. james held the tip of a 1-inch nail near the flat end of the 4-inch nail. jill closed the knife switch quickly and then opened it. the 1-inch nail was pulled toward the 4-inch nail. what is the best explanation of why the nail moved? a) electrical energy was converted to mechanical energy in the 1-inch nail. b) the 4-inch nail became an electromagnet and the magnetic force attracted the 1-inch nail. c) the electric current in the 4-inch nail was converted to mechanical energy in the 1-inch nail. d) the 4-inch nail had a positive charge and the 1-inch nail had a negative charge. opposites attracted.
