Dante is leading a parade across the main street in front of city hall. starting at city hall, he marches the parade 4 blocks east, then 3 blocks south. from there, the parade marches 1 block west and 9 blocks north and finally stops. what is the vector displacement and direction of the the parade, starting from the city hall and the stopping point?

displacement: 6.71 m, direction: 63.4 degrees north of east

displacement: 8.01 m, direction: 21.9 degrees north of east

displacement: 2.56 m, direction: 39.7 degrees north of east

displacement: 4.31 m, direction: 88.1 degrees north of east

The displacement is 6.71 [m} and the angle is 63.4° to the north of east

Explanation:

Using a sketch showing Dante's displacement, we can find each of the points Dante moves through. First, it moves 4 blocks east, the new coordinate (4.0), then moves 3 blocks south and we will get the new coordinate (4, -3). Then Dante moves 1 block west, thus the new point is (3, -3). And finally it moves 9 blocks north where the new coordinate in and gets -3 - (-9) = + 6.

The displacement can be found using the equation for the straight line.

We can realize that the triangle formed is a right triangle, therefore we can find the angle of the displacement.

come closer and become far apart and become steam/gas

-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
