If the bar magnet on the left were broken in half, what statement correctly predicts how the two halves of the magnet would react to the magnet on the right? A) Neither halves of the broken magnet would be attracted to the magnet on the right because a magnet must have two poles. Eliminate B) The two halves of the broken magnet would be attracted to each other, but neither would be attracted to the magnet on the right. C) Only the right side of the broken magnet would be attracted to the magnet on the right since it contains the south-oriented magnetic domains. D) The right side of both halves would be attracted to the magnet on the right since the south pole of each half would be facing the north pole of the other magnet.

D) The right side of both halves would be attracted to the magnet on the right since the south pole of each half would be facing the north pole of the other magnet.

Explanation:

According to the law of magnetism, "Like poles repel, unlike poles attract" If the bar magnet on the left is broken, both halves will consequently have two poles, the north and south poles. If the right sides of both halves are of the south pole, the bar magnet on the right is of the north pole. i.e. The south pole of both halves are facing the north pole of the bar magnet on the right. Therefore, both halves will be attracted to the bar magnet on the right.

i would think it's food chain

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it
