d. In many methods that employ multiple measurements, one particular type of measurement may be the "weak link" that limits overall precision. For the density measurements you made here, you will determine what contributes most to the CV of your calculated density - the measurements of mass or of dimensions. Typical standard deviation for measurement of length and of mass using the equipment employed in this lab are the following: Dimensions: 0.01 cm Mass: 0.002 g Select the data for your lightest object, focusing on its mass and its shortest dimension, and answer the following two questions:

Silica, sio2, is formed on silicon as an electrically insulating layer for microelectronic devices. silica is formed when silicon is exposed to o2 gas at an elevated temperature. at 900˚c, it takes 90 minutes for the oxygen to diffuse from the surface to form a 0.06 micron (0.06 x 10-6 m) thick layer of sio2 on

Chlorophyll a had the molecular formula c55h72mgn4o5 how many atoms are in this molecule

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
