Homework Statement Hello, The problem is quite simple. Estimate the mass of particules that contains the Earth's magnetosphere up to a distance of 100 times Earth's radius (In the shadow cone of earth) and also up to the break point or stopping point of the side of the sun.The solar...

Well, the mass of a proton is 1.67*10^-27 and i know that density equals volume divided by mass but i don't have a volume and i certainly don't see a way how to calculate it and furthermore there are distances which i don't knowwhat will be the use of them.

Well indeed it's a homework and i didn't get anywhere i can't figure out how to calculate the mass of particules.

Hello, The problem is quite simple. Estimate the mass of particules that contains the Earth's magnetosphere up to a distance of 100 times erath's radius (In the shadow cone of earth) and also up to the break point or stopping point of the side of the sun.The solar activity is at its minimum...

Ok thank you for your answers, it helped me a lot.

Hello, My question is quite simple. What kind of abuses does a spacecraft sustain from the moment it's launched until it's placed on orbit?I've always heard of what a spacecraft must face in the spatial environment but I've never heard of what it must face before it gets to it. Thank you.

Hello, The problem is quite simple.You are an astronautics engineer in an established colony on europa,one of jupiter's moons and your boss asks you what would be the minimum velocity so that a cargo full of wastes or garbage is placed on a parbolic (neglecting the mass of europa versus the...

hmmm well it's not precised but the average temperature in the corona is 10^6 K, i guess it will do.

Hello i have a problem with this question if anyone could help me ,that would be great. Estimate the thermal velocity of particles in the solar corona (take a distance two times the radius of the sun and assume that the particules have only two degrees of freedom), thus the thermal energy is...
