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.
Problem 1. [Projectile motion.]
A projectile is fired with the initial velocity v0 from the end of the building of height h.
The initial velocity makes angle θ with the horizontal (see the figure). The projectile
lands at a distance L from the end of the building.
(a) Find the symbolic equation for L as a function of v0, h, θ and gravitational
acceleration g. Show that in the limit h → 0 you recover the equation for the
projectile range on a level surface.
(b) Find the symbolic equation for the final speed vf of the projectile just before it hits the ground.
(c) Given that v0 = 30.0 m/s, h = 20.0 m, and θ = 30.0degrees, find the distance L and speed vf
