You are designing a concave mirror to project text onto a screen. The text consists of letters 6.00 mm tall, and the image of the letters should be 36.0 cm tall. The screen must be 8.00 m from the vertex of the mirror. How far from the vertex of the mirror should the text be placed, and what should the radius of the mirror be? You are designing a concave mirror to project text onto a screen. The text consists of letters 6.00 mm tall, and the image of the letters should be 36.0 cm tall. The screen must be 8.00 m from the vertex of the mirror. How far from the vertex of the mirror should the text be placed, and what should the radius of the mirror be? Solution here, the object height , ho = 6 mm = 0.6 cm the image height , hi = 36 cm the image distance , di = 800 cm the object distance , do = di * ( ho/hi) do = 800 * ( 0.6/36) cm do = 13.3 cm let the focal length be f using the lens formula 1/f = 1/di + 1/do 1/f = 1/13.3 + 1/800 f = 13.1 cm the radius of the mirror , r = 2*f = 26.2 cm .

Please help! Invasive species can be particularly troublesome, particularly in closed ecosystems, such as the Great Lakes watershed. The watershed functions as a closed ecosystem and this ecosystem has great difficulty adjusting to invaders. The Great Lakes radio consortium has several segments on invasive species; you can view the archived programs. In your opinion, how do invasive species affect biodiversity? .

please help me with these two thank you. What of the following describes a consensus sequence? A sequence was created that all proteins in the cell can bind to A sequence was discovered that is found in all genes in the genome A tandem repeat sequence in repetitive DNA expand to take up a large portion of a chromosome All sites that a particular protein binds to were aligned and compared to select determine the most common nucleotide at each position All living organisms go through the same flow of information from DNA to RNA to protein Which of the following are TRUE about transcribing RNA in bacteria. (*select all that apply) The 3 ' end of the RNA is synthesized before the 5 ' end RNA polymerase moves along in the 3 ' to 5 ' direction along the template strand "Coding strand" is another term for the template strand of DNA that is used for RNA synthesis In the bacterial genome, only one of the strands of the double helix is used as the template strand for synthesis of all genes Promoters have particular sequences (elements) found at 10 and 35 bases before the transcription start site The sigma factor helps RNA polymerase bind to the promoter A singla RNA can encode multiple different proteins Once synthesized, RNA must transported out of the nucleus before translation can begin In order to contribute to cellular functions, an RNA molecule must first be translated into protein Specific RNA sequences trigger termination of transcription through intrinsice (hairpin) or protein-mediated mechanism .
