WebNov 29, 2006 · Homework Equations P2 = P1 + dg (y1 - y2) d = density The Attempt at a Solution First I determine the pressure of the balloon by using P = mg/A, and I got 4.874 Pa Then I use the equation P2 = P1 + dg (h) 4.874 = (0) + (1.29) (9.8) (h). The 1.29 is density of air. I have no idea why I set p1 equal 0. The answer I got is wrong and I am stuck. WebApr 11, 2024 · The plane wave has an angular frequency ω and is traveling in the z-direction through a medium with density of mass ρ 0 and speed of sound c 0. The sphere has a radius R, a mass density ρ 1, and a speed of sound c 1. For simplicity, the origin of the coordinate system is positioned at the center of the sphere.

WebDec 22, 2024 · Density (ρ) is defined as mass (m) per unit volume (V): ρ =m/V. To calculate the density of a sphere, determine its mass, then measure its radius and use the expression (4/3)πr^3 to find its volume. In practice, it's usually easier to measure … WebThe Mass or Weight of a Spherical Shell calculator computes the volume of a spherical shell with an outer radius (r) and a thickness (t). ayuntamiento olivella

Which formula is correct to find the terminal velocity …

WebDensity of the object = \(\frac{m}{v}\) = \(\frac{36 g}{3 mL}\) = 12 g/mL Now, we know the density of both the elements that is the object and water. So, put the values in the specific gravity equation to know the answer. WebA sphere of known size and density is allowed to descend through the liquid. If correctly selected, it reaches terminal velocity, which can be measured by the time it takes to pass … WebFind the density of a sphere on Earth that weighs 4000 g and has a diameter of 150 cm. The first step is done for us (needed to convert 4000kg into g already g). Use formula … ayuntamiento olves
