The PICO broke up at one time and T is the temperature here. Given the values lumber maximum is opposed to 400 into tenders to power my nose. Nine meter flooding Known information From here we will get the UFT, which is 2.898 tenders took over minus divided by 11 a maximum, just 400 include enders to below minus night from here, Bigger than the two of them. Creature which is there in tow for five. 7 to 45 Calgary What a no For part B. We're here and we have mentioned the radios temperature, which is 800 Calvin. No, we know that the lenders was 2.89 Eat into tennis triple minus. From here you can find the do off Lambda Max that it was 2.898 And to turn this dough ball in my history. If I did by 800 this temperature. Now we get the reviews. Laundromats, monologist three one Done this revolver minus. I need you.
