To get the number of unstable atoms:
Column 3: take 900 - 90 = 810 The numbers from column 2
To get the Number of decayed atoms:
take the 810 * 10% = 810 * .1 = 81
Follow the pattern for the rest of the table.
It is the solar system because the planets are in it

acceleration of object ais help the acceleration of an object b OD
Given
v = 343 m/s
ac = 5g
ac = 5*9.8 m/s^2
ac = 49 m/s^2
where,
v: velocity
ac = centripetal aceleration
Procedure
We call the acceleration of an object moving in uniform circular motion—resulting from a net external force—the centripetal acceleration ac; centripetal means “toward the center” or “center seeking”.
Formula

The minimum radius not to exceed the centripetal acceleration is 2401 m.
