It is not possible to see very small objects, such as viruses, using an ordinary light microscope. An electron microscope can view such objects using anelectron beam instead of a light beam. Electron microscopy has proved invaluable for investigations of viruses, cell membranes and subcellularstructures, bacterial surfaces, visual receptors, chloroplasts, and the contractile properties of muscles. The "lenses" of an electron microscope consist ofelectric and magnetic fields that control the electron beam.As an example of the manipulation of an electron beam, consider an electron traveling away from the origin along the x axis in the xy plane with initialvelocity v,- vi. As it passes through the region x = 0 to x-d, the electron experiences acceleration a = a,i + aj, where a, and a, are constants. Forthe case v, = 2.00 x 10 m/s, a,- 7.52 x 1014 m/s, and a,- 1.68 x 10o15 m/s?, determine the following at x = d- 0.0100 m.%3D(a) the position of the electron(b) the velocity of the electronm/s i+m/s)(c) the speed of the electronm/s(d) the direction of travel of the electron (1.e. the angle between its velocity and the x axis)

As an example of the manipulation of an electron beam, consider an electron traveling away from the origin along the x axis in the xy plane with initial velocity vv. As it passes through the region x -O to x- d, the electron experiences acceleration aal+aj, where a, and a, are constants. For the case v,- 2.00 x 10 m/s, a, 7.52 x 1014 mys, and a, 1.68 x 105 m/s?, determine the following at xd0.0100 m. (a) the position of the electron m (b) the velocity of the electron m/s i+ m/s ) (c) the speed of the electron m/s (d) the direction of travel of the electron (1.e. the angle between its velocity and the x axis)

External stimuli are communicated to the brain by means of electrical signals propagating along nerve cells at a speed of approximately 25 m/s. Similarly, electrical messages are sent at the same speed from the brain along nerve cells to the muscles. Reflex actions are controlled by a relatively simple nerve circuit from a muscle to the spine and back to the muscle. Estimate the reflex time for a stimulus at the knee. (Assume that the signal resulting from the stimulus must travel a distance Δs = 1 m.)
