To maintain a constant speed, the force provided by a car's engine must equal the drag force plus the force of friction of the road (the rolling resistance). the density of air is 1.2 kg/m3.
(a) what are the drag forces in newtons at 77 km/h and 106 km/h for a toyota camry? (drag area = 0.70 m2 and drag coefficient = 0.28.) at 77 km/h n at 106 km/h n
(b) what are the drag forces in newtons at 77 km/h and at 106 km/h for a hummer h2? (drag area = 2.44 m2 and drag coefficient = 0.57.) at 77 km/h n at 106 km/h n supporting materials

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
