If you have 7 tennis balls 1 is heavier than the others and a balance How do you find which one is the heaviest only using the balance twice?
1- Take ou one ball and slit the other six into two groups of three balls
2- put the two groups in the balance ( first use ) and if they are the same weight then the ball you took out in the first place is the heavier if not and one group is heavier than the other then the heavier ball is in that group so you can exclude the other group and the ball you took out at first.
3- If one group is heavier than the other then you take one ball from that group ( it has 3 balss remember? ) and you weight the other two remaining balls ( second and last use of the balance ) if the two balls have the same weight then the ball you took out is the heavier one if not look to the balance to see which of the balls is lower and there is your answer.
Please, tell me if you understood : )

Does weight affect how far a catapult launches a tennis ball?
Yes, weight can affect how far a catapult launches a tennis ball.

However, the weight must be balanced and optimized to ensure the catapult operates efficiently and effectively.
You have 9 tennis balls. One is slightly heavier than the rest but you cannot tell by looking... or even holding. You also have a balance scale. How would you go about finding the heavy ball while usi?
Answer = Maximum of three steps to find heavy ball. Put one tennis ball aside and put the other 8 on the scale - 4 on each side. If the scale is balanced you're done - the one you put aside is the heavy ball If not Remove the 4 balls on the light side of the scale. The heavy ball is one of the four still on the scale. Spit these four in two on each side of the scale. Remove the two on the light side of the scale. The heavy ball is one of the two remaining balls on the scale. Split the two remaining balls. Your done. Solution #2 - heavier ball found in two steps: Step 1: group 9 balls in sets of 3. Reserve 3 balls(a), put 3 on each side of scale(b) and (c). Observe that heavier ball is in one of three sets, (a), (b) or (c) - either the scale side that dropped or the reserved set, if the scale balanced. Step 2: Split the set with the heavier ball - reserve one and place one on each side of the scale. Observe that heavier ball is one of the 3 balls, - either the scale side that dropped or the reserved ball, if the scale balanced. Solved in two steps.

Why do some tennis balls bounce higher than others?
Tennis balls bounce higher depending on factors like their internal pressure, felt quality, and core material.

The type of surface and conditions where the ball is being used can also affect its bounce height.
