In a lab a block weighing 80 n
WebIn a lab, a block weighing 80 N is attached to a spring scale, and both are pulled to the right on a horizontal surface, as shown above. Friction between the block and the surface is negligible. What is the acceleration of the block when the scale reads 32 N? (A) 2.0 m/s2 (B) 2.5 m/s2 (C) 4.0 m/s2 (D) 6.0 m/s2 (E) 8.0 m/s2. 69. Web6. To assess the accuracy of a laboratory scale, an object known to weigh exactly 1 gram is weighed n times and the mean scale weight, x, is com-puted. The scale readings are normally distributed with an unknown mean of µ and a standard deviation of σ = 0.01gm. How large should n be so that a 95% confidence interval for µ has a margin of ...
