A4kg block is sliding on a horizontal frictionless floor at a speed of 2.5ms and runs into a horizontal spring. the spring has a spring constant of 30nm. what is the maximum compression of the spring after the collision?

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
