Find the angle necessary to balance the moments from the following 3 masses in 3 dimensions. You are to balance the moments about plane A by adding a mass to plane B. The first mr is 426 g-cm at an angle of 276° and distance of -6.4 cm from plane A. The second mr is 764 g-cm at an angle of 288° and distance of -3.8 cm from plane A. The third mr is 248 g-cm at an angle of 323° and distance of 3.5 cm from plane A. The moments are to be balanced by putting mass on plane B which is 6 cm from plane A. (Enter your answer to the nearest tenth of a degree.) Type your answer. Previous Next
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.
