NOTE: This question involves Gauss's Law. I would think one would use the following formula: Φ = qen/ε0. I'm just not sure how to find Φ to solve for qen in Φ = qen/ε0. I'm not given an angle, so I can't use this formula: Φ = EAcosΘ. Help would be appreciated.
What is the flux if the angle is 600?
The coorect answer should have variable m in it
In the methane molecule, CH4, each hydrogen atom is at the corner of a regular tetrahedron with the carbon atom at the center. If one of the C-H is in the direction of and an adjacent C-H bond is at the direction . results to an angular bond of approximately 109o for a static frozen molecule. However, the molecule we can encounter everyday continuously vibrates and interact with the surrounding causing its bond vector to vary slightly. According to a new spectroscopy analysis, the adjacent bond vectors was found to be A = 0.95i + 0.87j + 0.99k B = 1.06i + -1.08j + -0.93k What is the angle (in degrees) between the bonds based on this new data?
