The speed is 0.2 meter per minute.
There is not enough information given in the question to determine the velocity.
Answer:
Time= t= 1.67 secs
Explanation:
Time= t=?= 1.67 secs
Initial Velocity= Vi = 2m/s
Final Velocity= Vf = 4m/s
Average Acceleration= av= Vf-Vi/t
Putting the values : 1.2m/s²= 4-2/t
Rearranging: t= 2/1.2= 1.67 secs
Answer:
PART 1
Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to 200 times as massive.
To conclude, Dwarf stars are small but have a high surface temperature. They are dimmer than the sun.
PART 2
The Hertzsprung-Russel Diagram also known as HR diagram is stars' scatter plot showing the relation of luminosity or absolute magnitude vs spectral class or surface temperature. The main sequence stars can be plotted on a HR Diagram as a diagonal band as their physical properties vary a lot.
The mass of these stars ranges from about a tenth of that of the Sun to about 200 times the mass of the Sun. Inside these stars Hydrogen fusion results in Helium. 90% of the stars, including the Sun, in the Universe lies in this category.Their surface temperature lies in the range of 2500 Kelvin to 40000 Kelvin.
So technically you would find a Dwarf star near higher temperatures but lower luminosity than stars like the sun.
Hope it helped!
Answer:
Atomic energy is produced from changes within the <u>nucleus</u> of an atom.
