What a healthy human problem. The speed off light in Zach's a horn is it? A call is equal. Thio Speed of light in Iraq You divided by their factory next offers their corn, so it's a shooting. Values three times into power. Eight. Divided by 1.92 trees refracting the zebra on this year's air speed off lighted circle. 1.58 times 10 Power eight Meeting per second, but be travelin teaser. Pony was light is given by the Linda Morning Record. The prevalent off light in vacuum divided by a factory. Next officer pone so it's truly valued. 632.8 is the prevalent office light in Iraq in 1.92 trees. Frankly, next excuse us rail and off lighting. Is there going to be 3 to 9 and a meter? But see we confined frequency that is a street of flight director Linda. Three times gentle power eight is the speed by the Lambda trees. 632.8 times. Don't phone minus nine. This gives us the frequency or 4.74 times 10 to the power 14. Hers
