WebThe method is based on Newton's equations of motion which are applied to discrete particles. The forces acting on each particle, e.g., the gravitational force or contact forces are balanced. Equation describes the translational velocity u i of a particle resulting from the force balance and Equation its rotational velocity ω i. All forces ...

Since the gap between … WebThe diameter of the m th dark ring was found to be 0.28 cm and that of the (m + 10) th 0.68 cm. If the wavelength of sodium light is 589 nm, calculate the radius of curvature of the lens surface. For the m th ring: [(0.14x10 … WebFor a 200cm radius, the surface sag over the 6cm diameter is: R − R 2 − d 2 4 = 200 − 200 2 − 6 2 4 = 0.0225013 c m. If instead the radius were 203cm, the surface sag would be: R − R 2 − d 2 4 = 203 − 203 2 − 6 2 4 = 0.0221687 c m. so that the difference is 3.3 × 10 − 4 c m or about 3.3 microns: only a few fringes in the ... birth of jesus bitesize
