It can measure from 0.0001 mg to 30 g. The electronic analytical balance used in the lab features a taring control that disregards the weight of the container on the pan. Thus‚ the value displayed on the balance only refers to the sample in the container. Ten 1-peso coins were then collected as samples. Each coin was weighed on the balance

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that
