If the mass of a moving object decreases from 100 grams to 25 grams, what happens to its momentum? (2 points)

Acylindrical specimen of a nickel alloy having an elastic modulus of 207 gpa (30 × 106psi) and an original diameter of 10.2 mm (0.40 in.) experiences only elastic deformation when a tensile load of 8900 n (2000 lbf) is applied. compute the maximum length of the specimen before deformation if the maximum allowable elongation is 0.25 mm (0.010 in.)

In a system, when potential energy decreases, then entropy also decreases. true false
