_____ suggested that the ships should be marked with load lines.


ANSWER

Samuel plimsoll


SOLUTION
A load line, also called Plimsoll mark found by Samuel plimsoli, is a marking indicating the extent to which the weight of a load may safely submerge a ship, by way of a waterline limit. The purpose of the load line is to ensure that a ship has sufficient freeboard (the height from the waterline to the main deck) and thus sufficient reserve buoyancy (volume of ship above the waterline).

Q5 Subjective Medium
Textbooks on science may give you a wrong impression that studying science is dry and all too serious and that scientists are absent-minded introverts who never laugh or grin. This image of science and scientists is patently false. Scientists, like anyother group of humans, have their share of humorists, and many have led their lives with a great sense of fun and adventure, even as they seriously pursued their scientific work. Two great physicists of this genre are Gamow and Feynman. You will enjoy reading their books listed in the Bibliography.
