A10 6 kg space-station in the form of a huge wheel is rotating at 0.2 rad/s. for purposes of this problem, you may consider it's center of mass to be at rest, and that all the mass is concentrated in the rim, which is 100 m from the center. a large meteor (5 x 105 kg) is speeding towards it at 700 m/s, along a line that would first hit the rim and then go through the center if it kept on going. the meteor hits the rim of the station, where it sticks. (a) what was the moment of inertia of the station before being hit? (b) what was the angular momentum of the station before being hit? (c) how fast is the center of mass of the station plus meteor travelling after collision? (d) how fast is the station now rotating after collision?

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

Occurs when an energy source transfers heat directly to another subject space; an example would be an object becoming warm by sitting in the sunshine

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit
