in this particular problem, the damage it off, it'll get corporate away is giving us said he's equal to 8.5 humanly. Mika. Uh, we need to convert it into maker. So 8.5, Do you like it? But 1000 because one motorist 1000 million bigger. So we get on Sarah's eight point to fight too England, and that is to my estimate. Also, it's Lent. L is given us one kilometer again. 12 cemeteries 1000 meter and we need to find the distance of the same because you notice are basically we need to use a formula in this case to start with the solution we need to use. The formulas are is equipped to rule into El upon a were rule stands for I write it here raises doohickey off that Madea, which is a standard value any changes asked for the market you and also he stands for going on six Nadiya all the way. No sista p. We need to first tell great the cross section again because you never had a is equal to buy our square since it's a so called everywhere which is equal to buy into D upon do the was good because damage it destroys it off Freddy's. Which is it going toe by magic glide by The damage it is human is e point. Do fight to include tenderness to my history. A funny too the whole square. Don't say that gate as my warranty. Five include Ennis to minus five. We discredit steps, see no standard value for cop it away, and it's for the steward. E is rue is equal to 1.72 into tennis to minus eight or meter in order to calculate the resistance. I mentioned the formula once again that it's legal imperative, Bonnie. So you're the 1.72 incorrect and these two minus it or Mika. It's a pack it great monkey plier by its lento fire that is Thomas C. Make it and area that we get regular as 5.35 in Brooke and Mr Minus Five because square, after calculating this, but I get the value as point the 0.321 homes, which you could mention it as t to one millions. Now this will be our final on cell photo at a distance everywhere
