a 50.0kg bicyclist on a 10.0kg bicycle speeds up from a 5.00m/s to 10.0m/s. solve the problem what was the total kinetic energy before accelerating?what was the total kinetic energy after accelerating?how much work was done to increase the kinetic energy of the bicyclist?is it more work to speed up from 0 to 5.00m/s than from 5.00 to 10.0 m/s?

What do animals wth echolocation have in common other than echolocation

Read the following scenario to answer the following question. in some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called "ligers." male ligers are sterile but some female ligers are fertile. in the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences. applying the biological species concept, the sterility of ligers reveals that a. lions are probably a subspecies of tigers b. tigers and lions are the same species c. a new species called "ligers" is forming d. tigers and lions are separate species
