Performing the Chemical Test by Reagent Strip The urine must be collected using appropriate technique and be tested within one hour ofcollection. If tests cannot be performed within this time, the specimen may be refrigerated for upto 8 hours.
Elastic and Inelastic Collisions. A perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision. An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision. Any macroscopic collision between objects will convert some of the kinetic energy into internal energy and other forms of energy, so no large scale impacts are perfectly elastic.
true or false 2.impulse is defined as the force exerted on an object times the time it lasts 3.if the net external force acting on a system is zero then the total momentum of the system is zero 4.when two objects collide and completely bounce apart with no lasting deformation or generation of heat the collision is said to be elastic 5.when two objects collide and completely stick together the collision is said to be inelastic 6.impulses are normally smaller when bouncing takes ...
