Fresh from their relatività speciale class, graffiti artists Avicenna and L. Bassi decide to test their acumen. They climb aboard opposite ends of a 21 m long train and synchronize their watches. The train starts up and quickly reaches a cruising speed of 180000000 m/s. (It is a very special train, indeed.) The plan? To investigate this funny concept called length contraction. At the predetermined moment on their watches, 1 minute after starting, they will open the windows and simultaneously spray their cans of paint, tagging the long brick wall beside the train. Since moving objects are contracted, the two spots will be closer together than 21 m.

Or will they be?

25pts the diagram shows the positions of the sun, moon and earth during spring tides, when the high tides are at their highest and low tides at their lowest. what is it about these positions that causes these high and low tides?

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
