Problem 3: A banked highway is designed for traffic moving at v = 82 km/h. The radius of the curve r = 347 m. Part (a) Write an equation for the tangent of the highway's angle of banking. Give your equation in terms of the radius of curvature r, the intended speed of the turn v, and the acceleration due to gravity g. Expression: tan(0) = Select from the variables below to write your expression. Note that all variables may not be required. B, y, 0, b, d, g, h, j, k, m, n, P, r, S, v Part (b) What is the angle of banking of the highway? Give your answer in degrees. Numeric : A numeric value is expected and not an expression. 0 =
Stellar evolution
We may see thousands of stars in the dark sky. Our universe consists of billions of stars. Stars may appear tiny to us but they are huge balls of gasses. Sun is a star of average size. Some stars are even a thousand times larger than the sun. The stars do not exist forever they have a certain lifetime. The life span of the sun is about 10 billion years. The star undergoes various changes during its lifetime, this process is called stellar evolution. The structure of the sun-like star is shown below.
Red Shift
It is an astronomical phenomenon. In this phenomenon, increase in wavelength with corresponding decrease in photon energy and frequency of radiation of light. It is the displacement of spectrum of any kind of astronomical object to the longer wavelengths (red) side.
Please answer question 3, the answer to part a is not tan(theta)= v^2/rg
