Question

QUESTIONS Q1. Both the meter stick and the vernier caliper can be used to measure the length of an object to 1/100th of a centimeter. Which, however, is the most accurate instrument? Why? Q2. Compare the volumes of the aluminum block as measured by the meter stick and the vernier caliper by calculating the percent difference of the two measurements. Based on the uncertainty of the measuring devices, which volume measurement is the most accurate? Can you verify this with the graph of your data? Q3. It is given that the density of aluminum is 2.70x10$^3$ kg/m$^3$. Show that this is equivalent to 2.70g/cm$^2$. Q4. Say you have a block of aluminum with dimensions of 3.54cm x 6.79cm x 2.2cm. Use the accepted value of the density of aluminum to determine the mass of this block. Make sure that you use the correct number of significant figures!
