4 dni temu · Archimedes’ principle is very useful for calculating the volume of an object that does not have a regular shape. The oddly shaped object can be submerged, and the volume of the fluid displaced is equal to the volume of the object.

1 dzień temu · Archimedes' Principle Simple Calculations. Example 1: Floating Object. Given: A wooden block with a volume of 0.5 m³ is floating on water (density of water, ρ f =1000 kg/m 3 ). Find: The buoyant ...
4 dni temu · Measurement of volume by displacement, (a) before and (b) after an object has been submerged. The amount by which the liquid rises in the cylinder (∆V) is equal to the volume of the object. The most widely known anecdote about Archimedes tells of how he invented a method for determining the volume of an object with an irregular shape.
3 dni temu · The formula for calculating the density of an object using water displacement is given by: \ [ D = \frac {m} {FW - IW} \] where: \ (D\) is the density in grams per cubic centimeter (g/cm³), \ (m\) is the mass of the object in grams, \ (FW\) is the final water level in milliliters (mL), \ (IW\) is the initial water level in milliliters (mL).
1 dzień temu · Explanation. Snell's Law states that the ratio of sine of angle of incidence and sine of angle of refraction is always constant for a given pair of media. \dfrac {\sin i} {\sin r}=\text {constant}=n=\text {refractive index} sinrsini = constant = n = refractive index. Let us consider that light enters from medium 1 to medium 2,
5 dni temu · To calculate the specific gravity of a substance, follow these easy steps: Isolate a known volume of the substance: V. Use a scale to measure the mass of that volume: m. Calculate the density of the substance with the ratio: ρ = m/V. Choose your reference substance and calculate its density: ρ₀ = m₀/V₀.
5 dni temu · However, in practical applications, it may be inconvenient and difficult to obtain the actual dimensions of the to-be-measured object. In this situation, if the image sensor plane is parallel to the object surface of the structure, as shown in Figure 1; meanwhile, the horizontal distance between the optical center O and the object surface, denoted by D, can be obtained by the distance ...
