Two ends of a steel wire of length 8 m and 2mm radius, are fixed at two rigid supports. Calculate the increase in tension in the wire when temperature fall by 10°C. [α steel =12x106K-1,ysteel=2x1011Nm-1]

in physics zero. in muscle fatigue could be high

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
