(10%) problem 8: two particles which have the same magnitude charge but opposite sign are held r = 6 nm apart. particle i is then released while particle ii is held steady; the released particle has a mass of 9.91 × 10-23 kg. particle i's speed is 110 km/s when it is 0.76r away from particle ii.

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.)

Which fators influence ocean currents

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?
