Chem question on dash-wedge structures - Physics Forums
Sep 18, 2008 · A dash-wedge structure is a representation of a molecule that shows the three-dimensional arrangement of atoms. It uses dashes and wedges to indicate the position of atoms that are either in front of or behind the plane of the paper, respectively.
Why is Understanding Wedge-Dash Diagrams Important for …
Apr 13, 2021 · A wedge-dash diagram can provide information about the stereochemistry of a molecule, including the relative positions of atoms and the presence of chiral centers. How is a double bond represented in a wedge-dash diagram? In a wedge-dash diagram, a double bond is represented by two parallel lines between the atoms, with two wedges or dashes on ...
Wedge-and-dash Molecular Structures in 2-dimensions - Physics …
Nov 19, 2009 · Homework Statement I'm having trouble drawing a wedge-and-dash, 2 dimensional molecular structure for Vitamin C (ascorbic acid). All of the diagrams I've looked at (on the Wikipedia page, and some .edu websites) are incomplete: they either don't include the carbon and/or hydrogens molecules, or...
How Do You Correctly Draw Enantiomers of Ibuprofen? - Physics …
Nov 2, 2010 · How are dash and wedge bonds drawn? Dash and wedge bonds are drawn by placing a horizontal line (dash) or a triangle (wedge) on the bond between two atoms. The dash is used to represent a bond pointing away from the viewer, while the wedge is used to represent a bond pointing towards the viewer. Can dash and wedge bonds be used in all molecules ...
Is 2,3-Dichlorobutane Really a Meso Compound? - Physics Forums
Jun 29, 2012 · It's more difficult to determine whether a molecule is a meso compound if it's not drawn as a Fischer projection. In the case that a molecule is drawn as a dash-wedge structure, one should attempt to recognize if it is a meso compound by exploiting symmetry instead of trying to superimpose images. However, exercise caution.
Equations of motion of a block on a spinning wedge - Physics …
Apr 1, 2020 · How is the motion of a block on a spinning wedge calculated? The motion of a block on a spinning wedge can be calculated using the principles of Newton's laws of motion and rotational dynamics. This involves setting up and solving equations that take into account the various factors affecting the system's motion.
Another Statics problem with friction - Physics Forums
Nov 29, 2014 · I broke the 400lb block with wedge touching it up from the wedge on the ground. I've got two FBD's I analyzed. Considering the 400lb block I summed forces in y to find Fn2. Then I considered the wedge to find P. The Attempt at a Solution The attachment has my solution. P should be 313lb I got 273lb.
Proof of Frobenius' Theorem: Directly Showing ##\\omega …
Mar 14, 2022 · Most of my texts have the standard proof of Frobenius' theorem (both the vector field and differential forms versions) and through multiple indirect equivalences conclude that ##\omega \wedge d\omega = 0## implies (locally) that ##\omega = \alpha d\beta## where ##\omega## is a 1-form and ##\alpha,\beta## are scalar fields.
What is the smallest horizontal force needed to move the crate …
Nov 15, 2016 · Wedge problems have many real-world applications, such as in construction, where wedges are used to lift heavy objects, and in engineering, where wedges are used in various machines and tools. They are also commonly used in physics and mechanics courses to teach students about the principles of statics and the importance of understanding forces ...
Block sliding down wedge (w/ friction), wedge on frictionless floor
Jun 21, 2010 · A large Wedge with mass 10 kg rests on a horizontal frictionless surface (think right triangle on a unit circle, theta <90 deg.). A block with a mass of 5 kg starts at rest (near the top) and slides down the inclined surface of the wedge, which is rough (does this imply friction?).
