You have five identical apples and six identical pears. The mass of an apple is 100 g and the mass of a pear is 101 g. You put all the fruit in a bag and place the bag on a scale. The scale reads 1100 g. Calculate the binding energy of the apple - pear system, in joules. Ignore the mass of the bag. Write your answer as E x 1014 J and type in just the value of E
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.
You have five identical apples and six identical pears. The mass of an apple is 100 g and the mass of a pear is 101 g. You put all the fruit in a bag and place the bag on a scale. The scale reads 1100 g.
