1. A tourist drops a rock from rest from a guard rail overlooking a valley. What is the velocity of the rock at 4.0 s? What is the displacement of the rock at 4.0 s? 2. Suppose the tourist in question #1 instead threw the rock with an initial velocity of 8.0 m/s [down]. Determine the velocity and displacement of the rock at 4.0 s (Remember the v i
19 cze 2024 · You can calculate the buoyant force with the following buoyancy formula: B = ρ × V × g. where: ρ — Density of the liquid the object is immersed in, measured in kg/m³; V — Volume of the displaced liquid, measured in m³; g — Gravitational acceleration in m/s²; and; B — Buoyant force.
We can use this same technique to determine the density of the fluid if the density of the coin is known. All of these calculations are based on Archimedes’ principle, which states that the buoyant force on the object equals the weight of the fluid displaced.
Objective: To learn how to use the Excel spreadsheet to record your data, calculate values and make graphs. To analyze the data from the Acceleration Due to Gravity Experiment by means of. a computer and a spreadsheet program and to learn the treatment of experimental errors.
Stated in words, Archimedes’ principle is as follows: The buoyant force on an object equals the weight of the fluid it displaces. In equation form, Archimedes’ principle is. F B = wfl, F B = w fl, where F B F B is the buoyant force and wfl w fl is the weight of the fluid displaced by the object.
Archimedes' principle states that the buoyant force on a fluid is equal to the weight of the displaced fluid. To calculate the buoyant force, we use the equation. buoyant force = density of fluid × volume of displaced fluid × acceleration due to gravity.
Vector equations – for constant acceleration the 5 equations involving, displacement, velocity etc can be used. · If asked to write an equation in terms of t for displacement/ velocity etc – simplify your equation as far as possible by collecting the i terms and j terms. e.g.
