A non-conducting sphere with radius a = 4.0 cm is inside a conducting shell with radii b = 15.0 cm and c= 20.0 cm as shown. Assume that the electric field at ri = 10.0 cm is measured to be 3.2×10³ N/C radially inward, while the electric field at r2 = 45.0 cm from the center is 1.5x10² N/C radially outward. a) What is the charge on the insulating sphere? b
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.
