Ablock with mass m= 6.7 is hung from a vertical spring. when the mass hangs in equilibrium, the spring stretches x = 0.29m. while at the equilibrium position, the mass is then given an initial push it downword and v 4.6 m/s. the block oscillates on the spring without friction.
1)what is the spring constant of the spring? 2)what is the oscillation frequency? 3)after t = 0.42 s what is the speed of the block? 4)what is the magnitude of the maximum acceleration of the block? 5)at t = 0.42 s what is the magnitude of the net force on the block?

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
