Excellent: Now we know that the heavy ball is A or B or C. To figure out which one it is, weigh any two against each other — say, A versus B. If one or the other is heavier, then you’ve found your answer. If the scale balances, then you know the heavy ball is C.
How do you weigh a ball?
Split the balls in two groups of three and one group of two. Compare the two groups of three using the scale. If one is heavier than the other, pick two balls from the heavier group and compare them on the scale. If one of them is heavier than the other, then that’s your answer.
What is the minimum number of steps required to find the heaviest ball out of the nine identical balls?
Or If they weigh the same weigh all the balls and divide by 9 if it is less than one of the balls you weighed the different ball is lighter. If it is more than one of the balls you weighed the different ball is heavier. Only 1 step required.
Which one is heavier a pound of bricks or a pound of feathers?
So this question is kinda tricky, But the answer is that they weigh the same. Because it is already mentioned that a feather weighs 1 pound and so a brick also weighs 1 pound.
Is the cue ball heavier than the rest?
Does a Cue Ball Weigh More? The cue ball in most sets will be the exact size and weight as the object balls. However, older coin-op pool tables may have one that is slightly bigger and heavier due to the mechanics of separating object balls from the cue ball under the table.
What is the weight of ball B?
Setting up the game 5.75 ounces/163 g, and shall measure not less than 8.81 in/22.4 cm, nor more than 9 in/22.9 cm in circumference.
How do you know the weight of a bowling ball?
3. Follow the 10% rule. A bowling ball should weigh 10 percent of your body weight (up to 16 pounds), which means you really shouldn’t be grabbing, say, an 8-pound ball if you weigh 150 pounds. You want some weight to the ball, but it shouldn’t be so heavy that it’s uncomfortable.
What is the minimum number of weighing?
So minimum number of weighing operations required is 5.
Is it possible to weigh 5 balls at the same time?
1. Put 3 balls on one end and 3 on the other. the last 2 are left on the table. 2. If one group of 3 is heavier than the other, then you can outweigh 5 balls since the second group of 3 and the group of 2 are all the same weight. If the groups of 3 are equal in weight, then you know that one of the 2 balls in the unweighed group is heavier.
How many balls are in a weighing pan?
1. 3 balls in each pan. 2. If the first weighing balances then weigh the remaing two. If they don’t balance then weigh any two from the heavier pan. If they balance then it is the other ball that is the heaviest. 3 v3 with 2 aside. 3 v3 with 2 aside. This will confirm which group the odd ball is in.
How many balls can you weigh on balance scale?
You have 12 balls identical in size and appearance but 1 is an odd weight (could be either light or heavy). You have a set of balance scales which will give 3 possible readings: (i.e. Left and Right have equal weight, Left is Heavier, or Left is Lighter). You have only 3 chances to weigh the balls in any combination using the scales.
How to find the heavier of the 8 balls?
You are given 8 identical looking balls. One of them is heavier than the rest of the 7 (all the others weigh exactly the same). You are provided with a simple mechanical balance scale. How can you find the heavier ball by using the scale only twice? Take 6 balls and split them into 2 groups of 3 balls each. Use the scale to weigh the 2 groups.
