When a marble is dropped in a bucket of water it sinks to the bottom. Is it because the marble weighs more than an equivalent volume of the water or the marble has greater mass volume than the water O?
All of the above? You can say the same thing in many ways. All of the following are different ways of saying the same thing, and all are correct: The marble sinks because the marble weighs more that an equivalent volume of water. The marble sinks because its density is greater than the density of water. The marble sinks because it has a greater mass than than same volume of water (and there is gravity/acceleration).
Would the total momentum still be zero if one marble had greater mass than the other marble?
If the momentum started as zero, yes, it would.
What is the probability of rolling a number greater than 4 and then pulling a red marble out of the bag without looking?
The probability of rolling a number greater than 4 is 2/6, that is, 1/3. For the probability of pulling out a red marble, more data has to be known. Just put the number of red marbles in the numerator, the total number of marbles in the denominator. Finally, multiply the two probabilities.
Is white marble softer than coloured marble?
Marble is a metamorphic rock and the hardness of the marble is determined by the indigenous rock of the area rather than color. There are some white marbles, such as Vermont White (from Brazil) that had a hardness close to that of granite.
How do you know if a fraction is more than half?
Double the numerator. If the answer is greater than the denominator then the fraction is greater than half.Double the numerator. If the answer is greater than the denominator then the fraction is greater than half.Double the numerator. If the answer is greater than the denominator then the fraction is greater than half.Double the numerator. If the answer is greater than the denominator then the fraction is greater than half.
