How would you find the volume of a stone by using water displacement?
Place a rock in a container, add water, and record the volume.Pour an unknown amount of water into a glass container, add the rock, and note the water level; the unknown amount of water plus the weight of the rock is the volume of the rock.Pour a known amount of water into a glass container, add the rock, and note the new water level; the difference in water levels is the volume of the rock.Water displacement will not work.

How is it possible to apply force to something but do no work?
Work is calculated as force multiplied by the distance the force is applied over. If the force is applied but the object does not move, no work is done because there is no displacement. So, it is possible to apply force without doing work if there is no movement of the object.
What other methods besides the water displacement method can you use to determine the density of a marble and a wire?
Water displacement, in and of itself, cannot be used to determine density. Density is defined as mass divided by volume. Water displacement determines only the volume part of density. Whatever method you use to determine volume, you still need to determine the mass of the item before you can calculate its density. That said, another way to determine the volume of an object is to measure its dimensions and apply the appropriate formula. A wire can be considered a cylinder. A very long and very thin cylinder, but a cylinder nonetheless. The formula for the volume of a cylinder is: V = lπr2 where l is the length of the cylinder, π is "pi", the ratio of a circle's circumference to its diamater, approximately 3.14159, and r is the radius of the cylinder, or half of its diameter. Simply use a ruler to measure the length of your wire. If it is bent, twisted, or kinked, you will need to straighten it out first. Instead of measuring the wire's radius, you should measure its diameter and divide by 2. Unless your wire is thick, it may be difficult to get an accurate measurement of its diameter, even in millimeter units. Instead, you might try cutting the wire into ten pieces and laying them all side by side, touching each other, then measure the total width of all then pieces, then divide by 20 to determine the radius of your wire. It is important that you use the same units for both length and radius of your wire. Once you have determined the length and radius of your wire, square the radius, then multiply it by 3.14159 (π), then multiply it by the length of the wire. That is your volume. If you measured your length and radius in millimeters, the volume will in cubic millimeters. A million cubic millimeters is equal to one liter, so if "liters" is the unit in the denominator of your density measurement, you will need to divide your "cubic millimeters" volume by 1,000,000 before computing density. A marble is a sphere. The volume of a sphere is determined by the formula: V = 4πr3/3 or V = πd3/6 where d is the diameter of the marble. To determine the diameter of your marble, place it on top of your ruler with the left side even with the zero mark, then measure where the right edge falls on your ruler. Again, this may not be very precise. Alternatively, you could make a mark on your marble, then place your marble on the ruler with the left edge at the zero mark and the mark in the exact center of the marble as viewed from above. Then roll the marble, one complete revolution, along the ruler, until the mark is again in the exact center, then measure where the left edge of the marble is again. This is the circumference of your marble. To determine its diameter, just divide by pi (3.14159). To determine the volume of your marble, multiply the diameter by itself, then by itself again (d x d x d, or d3), then multiply by pi (3.14159), then divide by six. This is the volume of your marble. If your diameter measurement was in millimeters, the volume will be in cubic millimeters.
Why isn't work done as you hold a book motionless over your head?
Work is the product of force and displacement in the direction of the force. When holding a book motionless over your head, the force applied is vertical while the displacement is zero. Therefore, no work is being done as there is no movement in the direction of the force.
What is the difference between direct and indirect measurement in surveying?
Direct Measurement: Apply the instrument directly to the unknown quantity. E.g. Taped distance, direction measured with a theodolite Indirect Measurement: Determined from its relationship to direct measurements. E.g. height difference determination in trigonometric leveling
What problem could you have if you tried to use displacement of water to find the volume of a sugar cube?
a sugar cube has air spaces in it. when put in water, the spaces will fill. the volume of water displaced will therefore be less than the original volume of the cube, so no
True or false one method used to measure the volume of an irregular solid involves immersing the object in the water?
Traditionally, displacement is when you place a solid in a known amount of liquid, then determine the volume based on how much liquid is displaced by the object. You can't displace a liquid with another liquid and find its volume. With that said, the statement "One method used to determine the volume of solids and liquids is displacement" must be completely true. However, as we established in the previous paragraph, displacement is not a method for finding the volume of a liquid. Because an "and" operator is used in the statement, that means displacement must apply to both solids and liquids, or the statement as a whole is unsound. And since we previously determined that displacement is not a method for finding the volume of a liquid, this makes the statement unsound and false.

Do component vectors apply to displacement?
Component vectors can be used with a variety of different used in physics, including displacement, force, acceleration, electric field, etc.
How is an Engine size measured in liters?
The liter is a measure of volume. When we apply volume measurement to engines, we are usually talking about the displacement in the cylinders of the engine. More displacement, though it consumes more fuel, increases power and performance (generally). We used to measure American cars engines' displacements in cubic inches, but we've shifted to metric units. Hence the liter. As an example, a Ford Mustang with 5.0 liters of displacement has an engine with just a shade over 305 cubic inches of displacement. There are other things about engines (and cars) measured in volume. Oil capacity, coolant capacity and petrol capacity are among the vital statistics.
How do you apply volume to a cone?
Cone volume = ( pi * radius2 * height ) / 3
Do component vectors only apply to displacement?
Component vectors can be used with a variety of different used in physics, including displacement, force, acceleration, electric field, etc.
How could you find the density of a potato?
first, you weigh it to get its mass. then you acquire its volume, since it has an irregular shape, you apply water displacement method. get a calibrated cylinder, note the initial water level and gently drop the potato in. measure the resulting water level and subtract it with the initial water level. this is your volume. density= mass/volume simply divide what you measured in grams with the volume of the potato (cm3). unit of density is grams per cubic centimeter or g/cm3
