In the video you watched above, Julie Chu of the 2008 US Olympic Hockey Team applied 100 lbs of force in .02 seconds. The .175 kg (the mass) puck left her stick at 80 mph (the video didn't say that, but it's a good guess). The conversion of 80 mph to m/s gives us 36 m/s. Quick "Google" conversion gives me 100 lbs is 445 Newtons. Let's use the what we know about the work energy theorem to come up with some interesting facts. Assuming the puck was at rest (initial velocity of 0 m/s), what was the pucks change in kinetic energy

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer
