A testable hypothesis must be just that--testable. You must be able to provide evidence that your hypothesis can be proven true in order for it to be considered accurate enough for future use among scientists. This can be done through repeated experimentation.
Answer: 241.5
Explanation:
Move the slider on the 100 gram beam to the first mark on the right, which is the 100 gram mark. If the pointer still is above the central mark, continue to move the slider to the right. Once the pointer drops below the central mark, move the slider back to the previous mark to the left. If the pointer drops below the central mark at 100 grams, move the slider back to zero.
Move the slider on the 10 gram beam to the 10 gram mark. Perform the same adjustments you did in the previous step until you find the appropriate slot for the 10 gram slider.
Repeat the same process with the 1 gram slider.
Add the values from each slider. For instance, if the 100 gram slider is on 200, the 10 gram slider is on 40 and the 1 gram slider is on 1.5, you would add 200 plus 40 plus 1.5 to get a total of 241.5 grams as the mass of your object in the tray.
