The queue for the ride is very long and you were starting to get impatient. Suddenly, the ride controller approached you and told you that he can get you and your classmates a no-queue ticket pass if you could answer his question about the rollercoaster. His question is, “Why is there a need for the rollercoaster car to increase its speed before entering a vertical loop?” # GEOLOGY: For their anniversary, Joey bought Kate a very expensive bracelet made of pure, 24-carat gold. Kate was very happy with the beautiful bracelet but said she couldn’t wear them. When he realized the reason why, Joey was enraged, not at Kate but at himself for buying the bracelet. Why can’t Kate wear the bracelet? thanks guyz... muaahh!!!
