Acompact car, mass 660 kg, is moving at 1.00 ✕ 102 km/h toward the east. the driver of the compact car suddenly applies the brakes hard for 2.1 s. as a result, an average force of 4.8 ✕ 103 n is exerted on the car to slow it down. (a) what is the change in momentum, that is the magnitude and direction of the impulse on the car?

What is the fate of the electrons that interact with a specimen in an electron microscope?

What is the momentum of a 2 kg object moving at 15 meters per second

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
