One tool scientists use to learn about the weather is radar. to use radar, a weather tower sends out radio waves and then detects the waves that are reflected back to the tower. If a great number of ratio waves are reflected back from a particular area, what does that tell scientists about the weather in that weather in that area? (A.) There is going to be a drop in air pressure in the area (B.) There is only sunshine in the area, with no clouds (C.) There is a light sprinkling of rain in the area (D.) There is a large amount of rain or snow in the area

(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.

Oxygen undergoes an isentropic expansion from 120 degree c and 280 kpa absolute to 140 kpa absolute. determine the final temperature of the oxygen and the amount of work per kg of o_2 produced in the process if it is adiabatic.

Work = force × a. work b. energy c. distance d. momentum
