How Does Solar Wind Affect Earth's Electric Environment?

AI Thread Summary
The discussion focuses on the impact of solar wind on Earth's electric environment, specifically examining the density and speed of protons in the solar wind. The proton density is noted as 8.90 cm-3, with a speed of approximately 490 km/s. Participants are prompted to calculate the current density of these protons and the total current Earth would receive if its magnetic field did not deflect them. A reminder is given to post homework questions in the designated section and to demonstrate initial work before seeking answers. The conversation emphasizes the importance of following forum rules for homework assistance.

Near Earth, the density of protons in the solar wind (a stream of particles from the Sun) is 8.90 cm-3 and their speed is about 490 km/s.

a. Find the current density of these protons.



b. If Earth's magnetic field did not deflect the protons, what total current would Earth receive?

You should:

1) post homework questions in our homework section

2) follow the rules there, of which the main rule is: show some work first.

I move this to hw, but you shouldn't expect any answer before you show some work.

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...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

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...
