Angular momemtum : mass * tangential speed * distance to the center = 50*2.1*3.6=37800 J.s
Explanation:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Answer:
True
Explanation:
The normal line is defined as the line which is perpendicular to the reflecting surface at the point where the incident ray meet with the reflecting surface.
The angle of incident is defined as the angle which is subtended by the incident ray with respect to the normal ray by consider the normal ray as the base line and angle is measured from the point where incident ray is incident on the reflecting surface of the mirror.
Similarly reflecting ray can be defined as the ray which is reflected after the incident of a ray and the angle subtended by the reflecting ray is measure with respect to normal ray by considering normal ray as a base line.
Therefore, the normal ray is the perpendicular line to the reflecting surface at the point of incidence.
Answer:
-main-sequence star
-protostar with jets
-contracting cloud trapping infrared light
-molecular-cloud fragment
Explanation:
The Life of a Star of about one Solar Mass. Small stars have a mass upto 1 1/2 times that of the Sun. Stars are planetary bodies that revolve in space. They are the combination of hydrogen and helium gases
seven main stages of a star formation are
A Giant Gas Cloud. A star begins life as a large cloud of gas. ...
A Protostar Is a Baby Star. ...
The T-Tauri Phase. ...
Main Sequence Stars. ...
Expansion into Red Giant. ...
Fusion of Heavier Elements. ...
Supernovae and Planetary Nebulae.
But ranking them according to the central temperature, from highest to lowest. will be
-main-sequence star
-protostar with jets
-contracting cloud trapping infrared light
-molecular-cloud fragment
