A student has a sample of a solid dissolved in a liquid. The task is to separate the mixture into its pure components. What question is best asked in the design of the experiment to determine how to separate the components?

A) Can the solution be filtered using filter paper and a funnel?
B) Can the solid be physically removed with forceps or a small manipulative?
Eliminate
C) Will the solvent evaporate at a different temperature than the solute in a distillation procedure?
D) Will the solid form a distinct layer on the bottom of the mixture when the mixture is not in motion?

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?

The three classes of rocks are sedimentary, metamorphic, and igneous. how are rocks classified into one of these three groups?
