Consider four different oscillating systems, indexed using . each system consists of a block of mass moving at speed on a frictionless surface while attached to an ideal, horizontally fixed spring with a force constant of . let denote the displacement of the block from its equilibrium position. order the systems from largest total mechanical energy to smallest. 1) m1= 0.5kg k2=500 n/m amplitude a = 0.02 m

2)m2= 0.6kg k2=300 n/m v2= 1 m/s . when passing through equilibrium

3) m3= 1.2kg k3=400 n/m v3= 0.5 m/s . when passing through x= -0.01 m

4) m4= 2 kg k4=200 n/m v4= 0.2 m/s . when passing through x=-0.05 m

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

Aforce is a vector quantity because it has both?

The momentum of a man riding his bicycle downhill can be calculated. the bicycle and the man have a combined mass of 40 kg. the velocity of the bicycle is 10 m/s. calculate the momentum.
