Answer:
Here is the full question
E = 420 − 7
s The elevation, E , in meters, of a skydiver s seconds after parachute activation is given by the equation above. What is the best interpretation of 420 as shown in the equation?
a) The skydiver started diving at an elevation of 420 meters.
b) The skydiver activated the parachute at an elevation of 420 meters.
c) The skydiver took 420 seconds after parachute activation to reach the ground.
d) The skydiver's elevation decreased by 420 meters per second after parachute activation.
Explanation:
Answers is that The skydiver's elevation decreased by 420 meters per second after parachute activation.
Answer:
3. Homogenous and unsaturated
Explanation:
Since your given information mentions 50 grams of solvent and 5 grams of solute, you must double each amount because "
Table G Solubility Curves" in the Regents Chemistry Reference Table notates curves based off of 100 g samples of water. Therefore, you must look for how soluble 10 grams of KCl is in 100 grams of water at 25 degrees Celsius.
As the picture shows, 10 grams of KCl is well below the curve for saturation, meaning that the solution is undersaturated.
As for the second part of the answer, we can tell that the solution is homogenous (of uniform composition) because there is no possibility of the salt, KCl, falling out of solution and making the mixture heterogenous (of mixed composition).
Putting all of those ideas together, we can tell that the answer to this question is:
3. Homogenous and unsaturated
Answer:
The difference is that the cumulative GPA covers shorter periods, like a term or a semester. The overall GPA refers to the average grades obtained by a student throughout his entire academic experience. This means the overall GPA includes grades from all terms and semesters.
