Acylindrical specimen of some metal alloy having an elastic modulus of 120 gpa and an original cross-sectional diameter of 3.8 mm will experience only elastic deformation when a tensile load of 1810 n is applied. calculate the maximum length of the specimen before deformation if the maximum allowable elongation is 0.46 mm.

Astone dropped into a well is heard to strike the water after 8seconds. find the depth of the well if the velocity of sound is 350m/s

Which situation will produce the greatest change of momentum

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
