Ohm Newton Meter Second Vernier caliper Meter stick 1 2 3 4 5 6 Copyright 2022 - Science Interactive | https://scienceinteractive.com Exploration True False Identify each statement as true or false. 1 The height and radius of a cylinder must be known before calculating its volume. Density is the ratio of the mass of an object to the volume it occupies. 2 The units for expressing volume are m . 2 Density varies with the mass of an object. The _____ is an example of a base unit of measurement associated with a physical object. meter kilogram second All of the above The _____ of the Vernier caliper is/are used to measure the exterior diameters and lengths of small objects. depth probe inner jaws outer jaws All of the above Multiple trials should be conducted when measuring objects with Vernier calipers in order to reduce random error. True False Copyright 2022 - Science Interactive | https://scienceinteractive.com Exercise 1 V = πr is used to calculate the volume of a _____. 4 3 3 cube cylinder sphere All of the above The density of an object can be used to determine its composition. True False 74 Word(s) Of the quantities recorded in data tables 4 and 5 the base measures are the measurements we physically measured such as finding the height of the cylinder by looking for the main scale and vernier coincidence measurements and computing a mean height in centimeters. Also, finding the mass of both the marble and the cylinder are base measurements. The derived measurements are the volume and density calculated for both the marble and the cylinder. Which of the quantities recorded in Data Tables 4 and 5 are base measures and which are derived measurements? Explain your answer. B I U 110 Word(s) Least count is the smallest number that is able to be measured on the vernier caliper. Zero error is the number that tells us if their is and offset of the vernier caliper. If there is an offset when closing the vernier calipers and looking at the placement of the main scale zero and the vernier zero then the zero error needs to be calculated whether it is a negative or positive zero error. Both the least count and zero error are computed before any measurements were taken to avoid any measurement errors and to be aware of the what the smallest measurement can be completed with the vernier calipers
