18. A certain isotope of the element lawrencium (Lr) has a half-life of 646s when observed at rest. Suppose you observed a sample of this isotope moving at a speed of .800c relative to you. a. What would you measure for its half-life? b. Suppose you saw half of the sample decay as it travelled from point A to point B. According to someone moving with the radioactive sample, what is the distance from point A to point 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.
half life? please help and show steps thank you!
