The serve is the most important stroke in tennis.\n\nLitell, Mifflin. Integrated Mathematics. Evanston, IL: 1995.

It was discovered during the annual meeting that the conversion noted in the ball specifications in the rules book are incorrect, and the tolerance for the diameter of the volleyball should be between 25.6 to 26.4 inches, which is less than the 25 ½ to 27 inches currently listed in the rules. Ball manufacturers will be given until the 2007 season to comply with the correct diameter conversion.\n\nThe ball is 9 to 10 oz. in weight, 25-1/2" to 26-1/2" in circumference, 8.5 inches in diameter. Usual inflation is between 4 and 6 lbs. air pressure.:-)

Selecting the right tennis racquet for you depends upon your level of play. If you are a beginner, you should start with a power tennis racket . If you have been playing for a while, let's say for a year, you probably should opt for one which gives you more control. Regardless of your level of play, there is a third factor which a tennis player should be aware of: comfort. You should choose a tennis racquet  which fits your physique and level of play and thus you are most comfortable to play with. By choosing the right racket, you also avoid the pain associated with tennis elbow which incidentally afflicts almost 50% of all tennis players in America. So having the knowledge about raquets is important in ensuring that you have the right tennis equipment which will help you tremendously in your quest to be a better tennis player.\n\n\nFor the average player, a combination of power, control, and comfort is probably ideal. \n\nCategory 1: Power Tennis Racquets \n---------------------------------\nManufacturers usually indicate in their packaging or internet description what category the model that they are selling belongs. These racquets feature oversize to super-oversize heads, are lightweight (8-9.5 ounces), longer (27-29 inches), stiffer and are balanced head-heavy (or evenly balanced) to retain enough weight in the hitting zone. These are designed for players with shorter, slower swings and who want more zing and pop. \n\nCategory 2: Control Tennis Racquets \n-----------------------------------\nDenotes tennis racquets that would be used by professional and more advanced players. These models are typically heavier in weight (11.5-13+ ounces), have smaller heads (85-98), thinner, more flexible beams and are balanced head-light to allow for more maneuverability. The result is low-power and designed for players who provide their own power and prefer one that offers more control. Can be standard or extended length. \n\nCategory 3: ‘Tweener Tennis Racquets \n-------------------------------------\nThere are several models that offer a blend of features from power and control racquets. They are often lighter (9.5-11 ounces), balanced anywhere from slightly head-light to slightly head-heavy, have midplus (95-102 square inches) heads and are usually extended length (27.5-28 inches). These models offer low-medium to medium-high power and are most appealing to intermediate-advanced players, seeking enhanced maneuverability.

Well, theres not enough information here. \nYou have to take into consideration, the angle of the ramp, the weight of the ball, whether the ball is pushed or released, the material which the ramp and ball is made of (their frictional properties)

I will assume that the one golf ball is heavier than the other twelve.\n\n1st weighing:\n\nSplit the golf balls into two groups of six, leaving one out.  Weigh the two groups.\n\nIf the groups balance, the 13th ball is the heavier of them all and the puzzle is solved.\n\nIf one group tips the scale, the heavier golf ball is in that group.\n\n2nd weighing:\n\nSplit the heavier group of six into two groups of three golf balls.  The heavier golf ball is in whichever group of three tips the scale.\n\n3rd weighing:\n\nSplit the heavier group of three into two groups of one and leave one out.  Weigh one golf ball against the other.\n\nIf they balance, the heavier golf ball is the one you did not weigh out of this group.\n\nOtherwise, the golf ball that tips the scale is the heavier golf ball.

An appendix to the "Rules of Golf" defines that a golf ball must not weigh more than 45.93 grams, that its diameter must not be less than 42.67 mm, and that its shape may not differ significantly from a symmetric sphere. Like golf clubs, golf balls are subject to testing and approval by the Royal and Ancient Golf Club of St Andrews and the United States Golf Association, and those that do not conform with the regulations may not be used in competitions (Rule 5-1).

Tennis is played on a rectangular flat surface, usually of grass, clay, or concrete (hard court). The court is 78 feet (23.77 m) long, and its width is 27 feet (8.23 m) for singles matches and 36 feet (10.97 m) for doubles matches. Additional clear space around the court is required in order for players to reach overrun balls. A net is stretched across the full width of the court, parallel with the baselines, dividing it into two equal ends. The net is 3 feet 6 inches (1.07 m) high at the posts, and 3 feet (914 mm) high in the center.\n\nThe court on the right side of each player is called the deuce court, while the left side is called the ad court.
