The diagram shows how air circulation forms a sea breeze on a warm day. A beach meets the sea in the middle of the image with a blue sky above containing a bright sun. On top above the water is A pair of arrows changing from red to blue pointing right toward the sea labeled 1 Return Flow. Then a blue arrow points down over the sea labeled 2 Cool. Then a pair of arrows going from blue to red point left labeled 3 Sea Breeze. Then a red arrow points up over the sand labeled 4 Warm. Which best describes what is happening in the diagram? At point 1, the air in the convection current is warmer and denser than at point 3 because its molecules contain more kinetic energy. At point 2, the air absorbs thermal energy from the surrounding air, which causes it to become heavier and sink. At point 3, the air in the convection current is cooler and lighter than the air in other parts of the current, so it is preparing to rise. At point 4, thermal energy from warm air over the land is transferred upward toward cooler areas of the atmosphere

1) sections 1, 2, and 10 are significant primarily because they suggest the likelihood that a) widow wycherly is actually the woman in the full-length portrait. b) dr. heidegger wants to include his guests in an experiment with the water. c) dr. heidegger plans to drink some of the water from the vase and needs witnesses. d) the guests will be asked to witness dr. heidegger's transformation when he drinks the water.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
