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.

3 dni temu · Water Displacement Formula. The formula for calculating the density of an object using water displacement is given by: \ [ D = \frac {m} {FW - IW} \] where: \ (IW\) is the initial water level in milliliters (mL).
5 dni temu · Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.
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.
1 dzień temu · It is given by the formula: \[S_{\text{Normal}}=t\left(1-\dfrac{1}{_{\text r}n_{\text d}}\right)\quad\text{where}\quad _{\text r}n_{\text d}=\mu=\dfrac{\text{real depth}}{\text{apparent depth}}\] Note that: \[\text{refractive index}(\mu)=\dfrac{\sin i}{\sin r}=\dfrac{\text{real depth}}{\text{apparent depth}}\]
The formula for the displacement 𝑠 is 𝑠 = 𝑢 𝑡 + 1 2 𝑎 𝑡, where 𝑢 is the initial velocity, 𝑡 is the time, and 𝑎 is the acceleration. This can be rearranged to make 𝑎 the subject, taking 𝑢 to be zero: 𝑎 = 2 𝑠 𝑡 = 3 . 9 2 9 / . m s
1 dzień temu · This simple formula generalizes to define moment of inertia for an arbitrarily shaped body as the sum of all the elemental point masses dm each multiplied by the square of its perpendicular distance r to an axis k. An arbitrary object's moment of inertia thus depends on the spatial distribution of its mass.
