The distance from earth to the nearest stor is about 4 x 1016 meters. How long would it take a radio signal traveling at the speed of light, 3,0 x 10 m/s, to make a one way trip to this star?

1 x 10^8years

2 x 10^3 years

300 years

4 years

2

4 x 10^4 years

terd muffin is the correct answer

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.
