I pull my child in a sled over the snow. The rope makes an angle with the horizontal so that the pulling force has a horizontal component of 16 N and a vertical component in the upwards direction 25 N . The combined weight of the child and sled is 84 N . I'm getting tired and so the sled is slowing at a constant rate of 0.80 m/s each second. Calculate the magnitude of the frictional force between the sled and the snow.

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
