Some years ago a unique proposal was made to raise the titanic. the plan involved placing pontoons within the ship using a surface-controll ed submarine-type vessel. the pontoons would contain cathodes and would be filled with hydrogen gas formed by the electrolysis of water. it has been estimated that it would require about 7×108mol of h2 to provide the buoyancy to lift the ship. what is the minimum electrical energy required to raise the titanic by electrolysis?

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
