document.write( "Question 29056: To estimate how long a thunderstorm will last, meteorologist can use the formula t= square root of d^3 over 216, where t is the time in hours and d is the diameter of the storm in miles.\r
\n" ); document.write( "\n" ); document.write( "1) A thunderstorm is 8 miles in diameter. Estimate how long the storm will last. Give your answer in simplified form and as a decimal(homework asked this, not me) \r
\n" ); document.write( "\n" ); document.write( "2) Will a thunderstorm twice this diameter last twice as long?Explain.

\"t+=++sqrt%28+d%5E3%29+%2F+216\"
\n" ); document.write( "[a] \"t+=+sqrt%288%5E3%29+%2F+216\"
\n" ); document.write( "\"t+=+sqrt%288%2A8%29+%2A+sqrt%284%2A2%29+%2F+216\"
\n" ); document.write( "\"t+=+8+%2A+2+%2A+sqrt%282%29+%2F+216\"
\n" ); document.write( "\"t+=+2+%2A+1.414+%2F+27\"
\n" ); document.write( "\"t+=+.1047\"
\n" ); document.write( "This is in hours
\n" ); document.write( "for minutes and seconds
\n" ); document.write( ".1047 hours x 60 minutes/hour = 6.284 minutes
\n" ); document.write( ".284 minutes x 60 seconds/minute = 17 seconds
\n" ); document.write( "so the time is 6 minutes 17 seconds
\n" ); document.write( "---------------------------------
\n" ); document.write( "twice the diameter would be 16 miles or 2*8 miles
\n" ); document.write( "\"t+=++sqrt%28+d%5E3%29+%2F+216\"
\n" ); document.write( "\"t+=+sqrt%28%282%2A8%29%5E3%29+%2F+216\"
\n" ); document.write( "\"t+=+sqrt%282%5E3%2A8%5E3%29+%2F+216\"
\n" ); document.write( "that's because (2*8) * (2*8) * (2*8) = (2*2*2) * (8*8*8)
\n" ); document.write( "[b] \"t+=+sqrt%282%5E3%29+%2A+sqrt%288%5E3%29+%2F+216\"}
\n" ); document.write( "notice the difference between [a] (the 2nd line) and [b]
\n" ); document.write( "the difference is the factor \"sqrt%282%5E3%29\"
\n" ); document.write( "so if you double the diameter this is the factor you multiply the time by
\n" ); document.write( "to get the new time.
