The experimenter from the video rotates on his stool, this time holding his empty hands in his lap. you stand on a desk above him and drop a long, heavy bean bag straight down so that it lands across his lap, in his hands. what happens? hints

The answer would be he will spin slower.  The bean bag is not spinning beforehand it contacts the experimenter, so (through conservation of rotational momentum) he must stock the rotational momentum mandatory to make it spin at the same degree as his lap. Consequently, he ends up spinning slower.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
