Answer:
The process in which heat flows by the mass movement of molecules from one place to another is C) convection.
Hope this helps :)
Answer:
3 m/s
Explanation:
Initial = Final
Mass * Velocity = Mass *Velocity
8000kg * 12m/s = (8000kg+ 24000kg) * (Final Velocity)
(96000 kgm/s) / (32000kg) = (Final Velocity)
Final Velocity = 3 m/s
Answer is 240 ohms
Use the equation V=IR, rearranging it to make R (resistance) the subject.
R = V/I
Substitute the values:
V = 120
I = 0.5
Resistance = 120 / 0.5
Resistance = 240 ohms
Answer:
D)they would generate so much power that they would blow themselves apart.
Explanation:
Stars contains helium and hydrogen gases with helium forming a large percentage. When a star is a few times greater than the Sun it could cause it to collapse into a black hole.
However when the mass of the star is 200 times greater than the sun, it means a larger percentage of helium gas which is formed by the fusion of hydrogen nuclei with a large amount of energy being the by product of this fusion process. This would make the Stars generate so much power that they would blow themselves apart.
