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 · 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 · 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).
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 · 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.
2 dni temu · Air mass is calculated based on the zenith angle using the formula: \ [ \text {Air Mass} = \frac {1} {\cos (\text {Zenith Angle})} \] The zenith angle should be converted to radians for this calculation. Example Calculation. For a zenith angle of 30 degrees: \ [ \text {Zenith Angle in Radians} = 30 \times \frac {\pi} {180} = \frac {\pi} {6} \]
1 dzień temu · The velocity of the object changes direction continuously, even if its speed remains constant, due to the centripetal force acting towards the center of the circle. ... Centripetal Force Calculation. A car of mass 1,000 kg is traveling at a speed of 20 m/s around a circular track with a radius of 50 meters. Calculate the centripetal force ...
