I see, thank you, that rule is new to me. However, what would be a good method for estimating the number of stars that turn into neutron stars instead of black holes in that range of 53? Surely it's not just dividing by half, or is it? I can think of several more 'fancy' steps, like (1/2)*total...
6M⊙ is in reference to the fact that in another subquestion, which I mentioned earlier, the main sequence ends a star with aforementioned mass. My lecture notes mentioned the ranges are:
0.8M⊙<M<5-8M⊙ produces a white dwarf
5-8M⊙<M<25-40M⊙ produces a neutron star
>25-40M⊙ produces black...
What would be the best way to take that into account? If I take into account that possibility, would I not need to take into account the number of stars in the 940 group, since quite a few stars from that range would form neutron stars too. In this case it would be in the 6-8M⊙ range, since it...
Try drawing a free body diagram and looking at the forces that are involved 1st. There are probably several ways to look at it, but this essentially would boil down to a box on a moving ramp problem.
Ah, I see, I understood the initial mass function as the star distribution that would result after stars stopped being produced as the question mentioned, ie that would be the current distribution , including the neutron stars.
I suppose the key I should have noticed was in another sub...
I am aware that stars 5-8 M⊙ up to 25-40M⊙ are likely to produce neutron stars upon reaching the end of their life-cycle. However, I am having trouble seeing how this helps me in estimating the number of neutron stars currently in the star cluster.
Homework Statement
An open cluster is observed to contain 1000 stars. Clusters contain many more low mass
stars compared to high mass stars, reflecting the star formation process. This depen-
dence of the number of stars formed in a given mass range is expressed in the so-called
initial mass...
The force initially applied does not have any torques but it is the friction itself that acts as a torque that rotates the ball equivalent to (frictional force*radius of the sphere)
Well, if you define impact as energy, which is suggested by your units, then what you need to do is apply the Conservation of Energy. In your case, you wan't a KE of 6.8J, hence you can equtae it with potential energy.
When we talk about magnetism, do we really take movement of a charge particle depending on the observer or do we take it form the point of absolute spacetime as our reference point? If it were the latter then it would make sense what you book is trying to present.
Show us your working and we can check it for you.
If one is attractive and the other repulsive that means that the coordinate cannot be between the particles. Sice your answer is, you should realize it soen't make sense.
Simply put though, one is ascociated with angular motion, circular motion is the most fundamental example.
The other is associated with sinusodial oscillations whether it is simple harmonic motion or variations in alternating current.
Start with the first one by actually finding friction. And if you remember the definition of work, you should know to multiply it in the distance moved in that direction.
Same concept applies for the other 2 thought the final one is a bit different,
Sorry, escape velocity is going a bit too far, literally and figuratively. You do not need to be at escape velocity to remain in orbit, because that is partly what escape velocities are, the object will be able to escape from the gravitaional influnce of the moon.
Try in an orbit, we assume...
Yes, you should give the exact question. The assumptions stated are neceessary for solving the question.
From your title, I take it that the balls do not lie and move on the greatest slope of the ramp?
