When solar flares increase solar wind from the corona what do they cause in earth's upper atmosphere?

They cause magnetic storms. A magnetic storm is a fleeting disturbance of the Earth's magnetosphere. A magnetic storm is caused by a solar wind shock wave associated with solar coronal mass ejections, coronal holes, or solar flares. It typically strikes the Earth's magnetic field 24 to 36 hours after the event.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
