In this video, the puck sits on a room-temperature aluminum ramp. Warmed by the ramp, the dry ice sublimates off the bottom of the puck and forms a thin layer of CO2 gas that levitates the puck, allowing it to slide down the ramp with very low friction. This process also creates a cool and mysterious smoky appearance of the puck, perhaps contributing to Einstein's excitement. The puck eventually compresses a spring and bounces back up the rampāwith clearly bewildered Einstein looking on. While energy conservation is at the heart of this analysis, you will have to use many different concepts and ideas to get all the answers. Don't disappoint Professor Einstein! Note that the screen has a superimposed frame counter, a linear scale, and a protractor scaleāall of them will be important in your analyses! Click play to watch the video below (text description of video), then answer the questions that follow.

Juju.01) 5 geologic events a group of students designed an experiment in an ice rink to represent the solar system. the steps of the experiment are listed below. 5: geologic events 1. choose a student to represent the sun. the planets are represented by two tennis balls. 2. ask the student to hold the tennis balls in each palm and spin on the ice with arms stretched out. 3. ask the student to draw in the arms after about 10 spins. 4. observe the student's arms rotate faster when they are closer to the body. 05 geologic events enors) the experiment most likely demonstrates that (2 points) 07 discussion-based sessment/module planets exert gravitational force on the sun the sun exerts gravitational force on the planets 3.07 discussion-based ssessment speed of a planet depends on its distance from the sun new version available!

what is your question? collegechemistry 5+3 pts in november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
