the object volume is equal to the water displaced, or 10ml. Density is 15/10 = 1.5g/ml

What is the volume of an object if you dropped a graduated cylinder and the water in the cylinder went from 40 ml to 65 ml?
65 - 40 = 25 ml
A material that is a solid and if dropped in water is very buoyant?
It is a substance that has a low density so that it only needs to displace very little water to equal its weight and so float.
Why will a water balloon dropped from six feet make a bigger splat than a water balloon dropped from 1 foot?
6 feet
What are the examples of rules in rounding numbers?
If the number to be dropped is less than 5, the number before it remains unchanged. Round the following number, so that the 4 is to be dropped. 2.6354 rounds to 2.635. If the number to be dropped is greater than 5, the number before it is rounded up. Round the following number, so that the 6 is to be dropped. 9.4046 rounds to 9.405. If the number to be dropped is 5, the number before it remains the same if it is an even number and is rounded up if it is an odd number. 2.685 rounds to 2.68 because 8 is an even number. 7.3075 rounds to 7.308 because 7 is an odd number.
How will knowing the density of a substance help you determine whether an object made from that material will float in water?
If an object is to float in water it must displace a volume of water equal to its weight; knowing the density of the substance that makes up the object allow a calculation to be made of the volume of water that must be displaced so that the object will float. If a substance has a density greater than that of water, it can be made to float by, for example, making it hollow; for example a ship made out of steel can be made to float as it has lots of hollow space inside it which means its effective density is less than that of water. Should the hull be compromised in any way, or by "splashing" over the top, the effective density can increase to the point where it is greater than that of water and the ship will sink. The density of water is not constant as it depends upon its temperature and things (like salt) dissolved in it; it was this change in density that led to loss of shipping and cargo which prompted the invention of the Plimsoll Line which is marked on the side of ships - it shows where the surface of water will be in different types of sea [water] for a given loading (the Line itself marks the maximum safe load). However, for small solid objects made of a substance of a greater density than that of water can still be made to float by using the surface tension of water: a clean sewing needle can be made to float if dropped very gently onto some water* as the force provided by the surface tension is enough to prevent the needle from passing through. If the surface tension is disrupted, for example by agitating the water, or by a drop of washing up liquid, the needle will sink. * If you don't have a steady enough hand: laying the needle on a piece of blotting paper or tissue paper and gently putting the paper on the water will make this easier to achieve - the paper will fairly quickly soak up water and sink away leaving the needle floating on the surface [tension].
A body whose mass is 60 g is dropped into a cylinder containing 150mL of water. The water rises to the 200mL mark. What is the density of the body?
50 ml.
If you have a graduated cylinder that contains ml of water you drop a rock into the cylinder and the water level rises to ml the mass of the rock is grams what is the rocks density?
density = mass/volume → The density of the rock is the mass of the rock divided by the difference in the volume from before the rock was dropped in and afterwards. Its units are grams/ml
If the mass of an object is weigh and the object is dropped in cylinder containing water but the object is not fully under water will this affect the density?
The density of what? But regardless the answer to that: Density is mass per volume. Mass is not influenced by the upward force of the fluid in which the object is submerged. The weight, on the other hand, is. Weight is a force, and mass is an amount of matter.
A 34.5-g gold is dropped into a graduated cylinder containing water by how many milliliters does the measured volume increase?
34.5/19.3=1.79mL (19.3 is the density of gold)
What are some things that can happen if you drop a piece of metal into a graduated cylinder partially filled with water?
It could sink. (The metal's density is greater than water.) It could turn into a ball of flames. (If you dropped a chunk of sodium into graduated cylinder, it would react with flames or sparks.)
A small object is able to remain suspended when dropped into a container of water. What does this tell you about the object's density in relation to the density of water?
It means that the object has an equal density to the water.
1988 jaguar xj6 is it 8 cylinder engine?
It's a 6 cylinder Someone may have dropped an 8 cylinder GM motor in the car, that is a popular thing to do
Can you calculate the volume of an item without knowing the density?
It is quite simple if it is a regular shaped object like a cylinder or a cube. For example if you wanted calculate the volume of a cylinder you need to know the radius of the circular cross-section of the cylinder - this is the measurement from the centre of the circle, to the outer-edge and then multiply that by the height of the cylinder. For irregular shaped objects don't think there is a simple mathematical way if you don't know the density but you can always use water displacement to get a volume measurement. Just drop the object you want to know the volume off into a graduated cylinder partially filled with water - the amount the level rises will be roughly equal to the volume of the object you dropped in.
What is a density column?
definitely something to do with polarity and solubility... A density column is created with dichlorofluoroethane(bottom),water(middle) and petroleum ether(top). Few crystals of iodine is dropped all the way down the cylinder and dissolve there. During the drop, some of the crystals color is only dissolve in certain layer(the top and bottom layer).
What if there is not enough water in a cylinder to cover a sample?
then you would have a problem to find out the right amount of volume of the sample that you dropped in the cylinder.
What will happen to a solid object with a greater density than water when it is dropped into water?
It will sink.
How do you find density of an object dropped in water?
You measure how many mL the water went up.
