To determine The person or observer agrees or disagrees with both the students. Explanation Sun continuously emits the electromagnetic radiation but the atmosphere on Earth protects us from those harmful radiations. The Sun emits Ultraviolet ray 7 % , visible ray 44 % and infrared ray 48 % in amount. The atmosphere reflects, absorbs and scatters all the radiation. Visible penetrates through atmosphere that is absorbed by Earth’s surface. The heated surface gives off infrared light that is absorbed by atmosphere

I do not understand the process to answer the second part of question b. Please help me understand how to get there!

Rank the six combinations of electric charges on the basis of the electric force acting on 91. Define forces pointing to the right as positive and forces pointing to the left as negative. Rank in increasing order by placing the most negative on the left and the most positive on the right. To rank items as equivalent, overlap them. ▸ View Available Hint(s) [most negative 91 = +1nC 92 = +1nC 91 = -1nC 93 = +1nC 92- +1nC 93 = +1nC -1nC 92- -1nC 93- -1nC 91= +1nC 92 = +1nC 93=-1nC 91 +1nC 92=-1nC 93=-1nC 91 = +1nC 2 = −1nC 93 = +1nC The correct ranking cannot be determined.

Part A Find the x-component of the electric field at the origin, point O. Express your answer in newtons per coulomb to three significant figures, keeping in mind that an x component that points to the right is positive. ▸ View Available Hint(s) Eoz = Η ΑΣΦ ? N/C Submit Part B Now, assume that charge q2 is negative; q2 = -6 nC, as shown in (Figure 2). What is the x-component of the net electric field at the origin, point O?
