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. It can also be used in calculating the density or specific gravity of an object.

27 cze 2024 · The basic formula to calculate displacement is a reworking of the velocity formula: d = vt. Where d is displacement, v is average velocity, and t is the time period, or the time it took to get from point A to B. If the object has constant velocity, solving for displacement is straightforward.
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).
18 cze 2024 · The wave equation is a second-order differential equation, meaning that it involves second-order derivatives of the displacement with respect to time and space. The general form of the wave equation is: ∂^2y/∂t^2 = c^2 ∂^2y/∂x^2. Where y is the displacement of the wave, t is time, x is space, and c is the speed of the wave. The wave ...

21 cze 2024 · This is the equation for the velocity at any time during the vertical ascent. At the top of the trajectory, the velocity is zero. We can solve the velocity equation to determine the time when this occurs: \(\LARGE \frac{V_{0}}{V_{t}}=\tan(\frac{gt(v=0)}{V_t})\) \(\LARGE t(v=0)=\frac{V_{t}}{g}\tan^{-1}(\frac{V_{0}}{V_{t}})\)
3 dni temu · It is described by the equation v = H0D, with H0 the constant of proportionality—the Hubble constant —between the "proper distance" D to a galaxy (which can change over time, unlike the comoving distance) and its speed of separation v, i.e. the derivative of proper distance with respect to the cosmic time coordinate.
