I am having difficulty in finding the answer to this questionMaria and Sharna were analyzing the data from their lab reportMaria had calculated the mass of an aluminum block to be 31.80 gSharna reported that the true mass must fall in the range of 31.800 g to 31.801 gDid Sharna correctly represent the uncertainty in their measurement? Explain.
Alpha rays can penetrate a piece of paperGamma rays can penetrate several centimeters of lead.
1.) A 2.) D Ihvinny is wrong, alpha rays can not penetrate a piece of paper- alpha rays are helium nuclei.
The question should read: Maria and Sharna were analyzing the data from their lab reportMaria had calculated the weight of an aluminum block to be 31.80 gSharna reported that the true mass must fall in the range of 31.800 g to 31.801 g The only way to know the answer to this is to know the quality and accuracy of their instrumentsIf their instruments are capable of measuring + or - .0005 g and the air displaced by the block weights .0005 g Then Sharma is correct RomeoMike - scientific measurment does not involce rounding and a rounding errer could not cause this discrepency Buoyancy
