Question 1: Complete the calculations of the table based on the data given below Test No Weight (N) H, (cm) H2 (cm) P.E. (initial) (J) P.E. (final) (J) Loss in P.E. (J) 60 43.0 1 1.8 | 60 2 2.0 44.4 2.2 60 45.7 Question 2: Complete the error calculations If the weight used in the experiment is having an uncertainty of 1.4± 0.01N, the initial height is measured, with an uncertainty of 50 ±0.05 cm and th calculated by the formula weight x height) Calculate, 1. The absolute uncertainty in the calculated value of Initial Potential Energy (in Joules) = 2) The absolute uncertainty in the calculated value of Final Potential Energy (in Joules)

What is the difference between accuracy and precision? Explain 2. Calculate the volume and percent error/uncertainty in the volume of a rectangular sample block of length 13.51 ±0.05 cm, width 6.23 ±0.02 cm, and thickness of 1.76±0.02 cm. 3. Calculate the mass density and uncertainty in the mass density of the sample block. Mass of the block is 289± 1gr. 1.
