Complete question: The chart shows the movement of a ball after several seconds.

Column A is on the x-axis, and Column B is on the y-axis. Which titles should replace A and B?

a. Column A should be “Time,” and Column B should be “Position.”

b. Column A should be “Position,” and Column B should be “Time.”

c. Column A should be “Velocity,” and Column B should be “Speed.”

d. Column A should be “Speed,” and Column B should be “Velocity.”

Answer:

Column A should be "Time," and Column B should be  "Position"

Explanation:

In general, the first column always refers to the x-axis, this is the independent variables. While the second column refers to the y-axis, the dependent variables.

Option A) names Time and Position to the columns. This seems to be correct as time is an independent variable, while the ball position depends on time. The x-axes is named "time", and the Y-axes is named "ball position".

Option B) is not possible because the Position is not the independent variable, and time is not the dependent variable.

Option C) and D) are not possible, as both of them are variables that depend on time.

Calculate the number of neutrons in an atom of an element that has a mass number of 98 and an atomic number of 42
olya-2409 [2.1K]
There are 56 neutrons. To find them, you just have to subtract the atomic number with the atomic mass. If you dont know, the atomic number is the number of protons (and electrons) in an atom. The atomic mass is the number of both the protons and neutrons. Of you subtract the atomic number, you get protons.
