AI Thread Summary
Neutron stars are incredibly dense, with a typical mass of 2.7 x 10^28 kg and a radius of 1.2 x 10^3 m. To find the density, the formula density = mass/volume is applied, leading to a calculation of the star's density. Additionally, if a dime were made from neutron star material, its volume of 2.0 x 10^-7 m³ would result in a weight of approximately 2.2 pounds. The discussion highlights the need for clarity on relevant equations and problem-solving approaches in physics. Overall, the density of neutron stars and the weight of a dime made from their material are key focus points.

Homework Statement


Alright, this chapter in my AP Physics class has been giving me all sorts of problems, so need tons of help. Here is the first problem:
Neutron stars consist only of neutrons and have unvelievably high densities. A typical mass and radius for a neutron star might be 2.7 x 10^28 kg and 1.2 x 10^3 m. (a) Find the density of such a star. (b) If a dime (V=2.0 x 10^-7 meters cubed) were made from this material, how much would it weigh (in pounds)?


Homework Equations


I'm not sure what equations are relevant, but I will give it a try: P+.5p(v)^2+pgy=p+.5pgy


The Attempt at a Solution


I don't really know any of this so I don't know where to start. Any help would be appreciated, Thanks.

Density = mass/volume

2.2 pounds = 1 kg
 
Thanks, that was a lot simpler than I thought it would be.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
