Ejercicios de Laboratory: measurement, errors, elasticity and fluids

6 ejercicios de Laboratory: measurement, errors, elasticity and fluids que han salido en los exámenes de Física II de la URV (Grado en Química) 2022-2024.

Ejercicio Lab 1 · 2024

Explain how the volume resolution error changes when determining all length dimensions solely by caliper instead of other instruments, compute the magnitude of this change, and discuss whether random error is affected.

Ejercicio Lab 4 · 2024

Theoretically evaluate the center of gravity coordinates (X_CG, Y_CG) of a flat homogeneous 10 cm x 10 cm plate with a central top cutout leaving two side arms of width 3 cm and a base of height 3 cm.

Ejercicio Lab 5 · 2024

A sphere with diameter 2.12 cm has mass 126.75 g in air and apparent mass 122.18 g in a liquid. Calculate: a) the buoyant force exerted by the liquid, b) the density of the liquid.

Question 3 (Pract 4) · 2022

Draw the complete schematic diagram representing the experimental setup used during Practice 4.

Question 4 (Pract 5) · 2022

Using the data obtained in the laboratory, justify quantitatively whether the experimental uncertainty related to the weight measurement or that of the diameter measurement has a greater influence when calculating the density of a liquid. Furthermore, determine the additional relative error introduced if pi is…

Question 6 (Pract 7) · 2022

Complete the circuit diagram corresponding to the setup constructed during Practice 7 in the laboratory.
