Answer to: Describe how to determine the density of an irregular object. By signing up, you'll get thousands of step-by-step solutions to your...
Citationsy was founded in 2017 after the reference manager Cenk was using at the time, RefMe, was shut down. It was immediately obvious that the reason people loved RefMe — a clean interface, speed, no ads, and simplicity of use — did not apply to CiteThisForMe. It turned out to be...
Several 3D FullWAVE FDTD simulations were performed at a fixed wavelength, at various incident angles of the illumination to determine the optimal angles at which light is coupled into each of the three metal-strip waveguides. Figure 1: Schematic of the surface-plasmon spatial multiplexer Figure 2...
There's always a little confusion between mass and weight. Mass, which is the quantity you need to determine density, is a body's inherent inertial resistance to a change in motion, but weight is the force exerted by gravity on the body. Mass can be measured in kilograms, but weight is...
The direction of these unit vectors is in the x-, y- and z-directions respectively, as shown in the diagram. Diagram of three unit vectors. Examples of Unit Vectors To determine if a vector is a unit vector, it is possible to check if the length is one. Consider the vector given ...
Answer to: How do I get from mgh=\frac{1}{2}mv^{2}+\frac{1}{2}I\omega ^{2} (where ''I'' is the moment of inertia of a cylinder with uniformly...
Calculating magnitudes for forces is an important part of physics. When you're working in one dimension, the magnitude of the force isn't something you have to consider. Calculating magnitude is more of a challenge in two or more dimensions because the force will have "components" along both...
Similar to shoe trees, boot stretchers are shaped like feet and can be adjusted so you can reshape steel toe boots according to your preferred dimensions. Moreover, they can also make boots wider, up to one size bigger than they originally are. ...
Learn how to calculate the vector components of an object’s velocity in two dimensions and see examples that walk through sample problems step-by-step for you to improve your physics knowledge and skills.
The Cut Line feature, used to determine the shortest line between objects. Limitations and Uses of Calculating Distances in COMSOL Multiphysics® These techniques for determining distances can be used in any model. Although the examples presented here are in 2D, they can all be generalized to 3D...
