With a speed of v(initial), a perfectly rounded mass ball as known as “m” is moving towards the left and touches a uniform disc of mass as known as M and radius as known as R which is covered in super glue that instantly sticks whatever it touches and is pivoted about its center. Find the answers to the following questions How fast is the whole system rotating after the collision? Before coming to rest, to what angle will the system rotate?
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.
