4. Calculate:the mass of the light bulb is the sum of the values on each rider. To get magnified view of the 1-gram rider,place the cursor over that rider (each tick mark represents 0.1 g.)

100-g rider:___________

10-g rider:___________

1-g ruder:___________

Note because the position of the 1-g slider can be estimated to the nearest 0.01 g, the mass measurement is typically recorded to the nearest hundredth.for example, we would write 201.32 g or 146.70 g if the slider is exactly on a 0.1-g tick mark.

5. Practice:use the gizmo to find the mass of the other objects.write their masses below.
