Calculate the mass of PbCl2 formed when an excess of 0.100 M solution of NaCl is added to 0.4L of 0.7 M Pb(NO3)2. Pb(NO3)2 + 2 NaCl --> PbCl2 + 2 NaNO3
A 0.60 kg ladle sliding on a horizontal frictionless surface is attached to one end of a horizontal springPhy(k = 430 N/m) whose other end is fixed. The ladle has a kinetic energy of 8.6 J as it passes through its equilibrium position (the point at which the spring force is ze...
(a) At a certain instant, a particle-like object is acted on by a force F=(2.9N)i-(1.7N)j+(5.7N)k while the object's velocity is v= -(3.2m/s)i+(4.5m/s)k. What is the instantaneous rate at which the force does work on the object? (b) At some other time, the velocity consist...
