A solid disk of mass =0. 800 kg and radius =0. 250 m is suspended vertically and is free to rotate about its center without friction. A point object that has the same mass as the disk is placed at an angle thetai=30. 0â clockwise from the top along the rim, causing the disk to rotate. The acceleration due to gravity is =9. 80 m/s2. What is the angular speed f of the disk when the object is directly below the center of the disk.

Athermometer is removed from a room where the temperature is 70° f and is taken outside, where the air temperature is 10° f. after one-half minute the thermometer reads 60° f. what is the reading of the thermometer at t = 1 min? (round your answer to two decimal places.) ° f how long will it take for the thermometer to reach 30° f? (round your answer to two decimal places.)

(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.
