The heat developed in an electric wire varies jointly as the wire's resistance, the time the current flows, and the square of the current. in two minutes a current of 5 amps develops 1,200 heat units in a wire of 8 ohms resistance. what resistance does a similar wire have, which develops 6,000 heat units with a current of 10 amps in 5 minutes?

The lengths of nails produced in a factory are normally distributed with a mean of 4.91 centimeters and a standard deviation of 0.05 centimeters. find the two lengths that separate the top 4% and the bottom 4%. these lengths could serve as limits used to identify which nails should be rejected. round your answer to the nearest hundredth, if necessary.
