Change in rotational kinetic energy Homework Statement A disk of mass m1 is rotating freely with constant angular speed ω. Another disk of mass m2 that has the same radius is gently placed on the first disk. If the surfaces in contact are rough so that there is no slipping between the di...
Change in Earth's gravity & rotational KE due to changes in Radius Homework Statement Let g be the acceleration due to gravity at the Earth's surface and K be the rotational kinetic energy of the Earth. Suppose the Earth's radius decreases by 2%. Keeping all other quantities constant, (a...
This three-dimensional distribution of the fluid density can be resolved by recording with the optical setup several projections in different directions through the flow and processing the obtained data with the methods of computer tomography. If the flow has rotational symmetry, one projection only ...
Recently I was searching the internet and books for the connection between conservation of angular momentum and conservation of rotational energy and found nothing. Let's say an ice skater rotates and draws the arms in - the rotation speeds up. The rotational energy must increase because the......
The larger the surface energy density, the more uniform the distribution of particles. When the particle size is 2.0 mm, the particles in the surface energy density conditions of 0.1 J/m2 and 1.0 J/m2 are in the bottom of the pipeline concentration aggregation area. When the particle size ...
From the slope of the Arrhenius-type diagram of ln(fr/T) versus 1/T shown in Figure 10a,c for low- and high-frequency relax- ation, we could estimate the activation enthalpy for the unimolecular equilibrium between different rotational isomers and dimerization reaction of Nisin, respectively. ...
