What is the percentage error in the area of the plate?   %. (Remember to exclude the % symbol with your answer.)




参考答案: 6


本题详细解析:
Area involves a multipli*cc523 o o 4ffhzp22 b2oc;p:mkjrpx dcation so the percentage uncertainties need to be added. Uncertainty in length is one part in 50, i.e. 2%; and in the heij2*rozcp m2 o 2xcp 5hcf3o k:fpd4b;2ght it is one part in 25 or 4%. Adding the uncertainties gives 6%.
