In an industrial gun, when the trigger is pulled a gas under pressure is released into the barrel behind a ball of mass . The ball slides smoothly inside the barrel and the force exerted by the gas on the ball varies as Where is length of the end of the barrel from the initial position of the ball and is instantaneous displacement of the ball from its initial position. Neglect any other force on the ball apart from that applied by the gas. Calculate the speed of the ball with which it comes out of the gun.

QUESTION7 Calculate the signal attenuation along a neuron of radius 5 μm after the signal has traveled a distance of 900 μm. The ratio of the axoplasmic resistivity to the wall resistivity is 0.5. Note that the signal attenuation is the amount by which the voltage has decreased after traveling a distance, and it is given by the Attenuation Factor (AF). QUESTION8 Calculate the ratio of the speed of propagation of a myelinated neuron to a non-myelinated neuron. The myelinated neuron radius is 7 μm and has capacitance per unit area of 5x10^-5 Fm^-2.
