Who discovered blue giant stars?

Blue giant stars were not discovered by one person, as they have been observed and studied by astronomers over time. However, they were first classified and extensively studied by Annie Jump Cannon and Ejnar Hertzsprung in the early 20th century.


Who was the first person to classify stellar spectra by temperature?

Many people were involved in the current spectral classes.The person who first realised that the spectral sequence then categorised was in fact temperature, was Cecilia Payne.See related link for more information on her.


Who discovered star life cycles?

The life cycle of stars was primarily discovered by astronomer Annie Jump Cannon in the early 20th century through her work on stellar spectra and classification. Additionally, the theoretical framework for understanding stellar evolution was further developed by astrophysicists like Ejnar Hertzsprung and Henry Norris Russell.


When a cannon is fired will the cannon and cannon ball will have the same amount of kinetic energy?

No, the cannon and cannonball will not have the same amount of kinetic energy when the cannon is fired. The cannonball typically has more kinetic energy due to its higher velocity compared to the slower-moving cannon.


When a cannon is fired the cannon and cannon ball will have the same amount of kinetic energy?

No, the cannon will have less kinetic energy compared to the cannonball due to its smaller mass. Kinetic energy is proportional to an object's mass and velocity, so the faster and heavier cannonball will have more kinetic energy than the slower and lighter cannon.
