Q: In an experiment, a student measures the mass of an object as 200 g with an uncertainty of ±5 g. What is the range of possible values for the mass?

Solution: Range = Measured value ± Uncertainty = 200 g ± 5 g = 195 g to 205 g.

Steps: 5

Step 1: Identify the measured value of the mass, which is 200 g.
Step 2: Identify the uncertainty, which is ±5 g.
Step 3: Calculate the lower limit of the range by subtracting the uncertainty from the measured value: 200 g - 5 g = 195 g.
Step 4: Calculate the upper limit of the range by adding the uncertainty to the measured value: 200 g + 5 g = 205 g.
Step 5: Combine the lower and upper limits to find the range of possible values: 195 g to 205 g.
