Answer to Question 1

Answer: In any tug of war, the tension on both ends of the rope is the same, so the winning team is the one that exerts more force on the floor. Socks slip easily on a smooth floor, preventing the boys from pushing on and being pushed by the floor. Newton's third law

Answer to Question 2

Answer: The carpeted floor has more give, which means it takes more time for the momentum of the falling glass to reduce to zero as it hits the surface. More time means less force, which means less chance of breaking upon contact with the carpeted floor.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
