Why do you think the drag force on a car depends on the density of air?
The drag force on a car depends on the density of air because drag force is directly proportional to the air density. This is due to the fact that air density affects the number of air molecules present in a given volume, which in turn impacts the number of air molecules that the car must displace as it moves through the air. Therefore, a higher air density results in a greater number of air molecules that the car must push aside, leading to a higher drag force.
Does density change if you change the size?
Answer #1:Yes, assuming the mass stays the same.==================================Answer #2:A large amount of a substance has the same density as a small amount of the same substance.A gold nugget has the same density as a gold bar.A tank-car-ful of fresh water has the same density as a glass of fresh water.
What does a hydometer measure?
A hydrometer measures the specific gravity or density of a liquid, which is often used to determine the alcohol content in beverages like beer or wine. It can also be used to check the electrolyte levels in car batteries.
How can water displacement be used to measure the density of irregularly shaped solid?
Density is mass per unit of volume of a material. If you have a solid of homogeneous material, weigh it. Then take a container filled to a given level with water. Immerse the object and note the new water level. Compute the difference in level and you'll know how much water was displaced by the object. This is equal to the volume of the object. With its volume and mass known, divide the mass by the volume to get the mass per unit of volume. This will be the density of the material your object is made of. Let's say you have a "funny-shaped" silvery metal object, and it displaces 100 cubic centimeters of water. If it weighs 270 grams, it will have a density of 270 grams / 100 cubic centimeters or 2.7 grams per cubic centimeter. Your object may very well be made of aluminum, as aluminum has a density of 2.7 grams/cc.
How do you calculate the relative density of a substance?
To calculate the relative density of a substance, you divide the density of the substance by the density of water. The formula is: Relative Density Density of Substance / Density of Water. The relative density is a measure of how dense a substance is compared to water.
If ethylene glycol has a density of 0.958 which car would be better prepared for cold weather car A with a radiator fluid density of 0.976 or car B with a radiator density of 0.989?
0.976
What mineral has a density of 7.5 and a is used to start a car?
Nagyagite is the only mineral with a density of 7.5
What is the density of the fluid in a car battery if it has a volume of 125ml and a mass of 155g?
density = mass / volume = 1.24 g/ml
Does density vary with the of volume of a body?
The density of an object is its mass divided by its volume.The density of an object varies inversely with its volume.Thus, if you can compress and object, like a sponge, you can increase its density.Normally, we say the density of a type of material is an intrinsic property, i.e. if you have a big piece of it or a small piece of it, they both have the same density because the large piece has a proportionately larger volume than the small piece.So, a gallon of water has the same density as a milliliter of water.Note the distinctions here.1. An object, like a car, can be made of many different materials and the object, as a whole, has some density which is the mass of the car divided by the volume of the car. If you crush the car, you increase its density.2. Each type of material also has a density. The glass in the window of the car has its own density, a property inherent in that type of glass. The steel in the car has the density of steel, a property inherent in that type of steel.If you have a type of material and you compress it, you increase its density.If you don't compress it, then two different pieces of the same uniform material, large or small, will have the same density under the same conditions of pressure and temperature. That is what we mean by density is an intrinsic property of a material.
Is density is mass per unit volume?
Yes.
Do car tires sink or float?
no, a car tire will sink immediately after hitting the surface. The density of the rubber disallows the tire from floating.
What material is the out of a car bumper made of?
generally the car bumper is made up of steel. it can be heavy by using heavy density oil in it.so the car can met the accident withstand its position
What is the density if a car has a volume of 125mL and a mass of 155g?
Density = mass/volume = 155/125 = 1.24 g/cm3.
What is the purpose of cold air intake on a car?
Cold air has more density than hot air.
How is density used to determine if your car battery is good?
The electrolyte in a car battery is sulfuric acid, diluted with water. The density of the acid when fully charged is 1.265g/cm3. The chemical process, as the battery is discharged, makes the acid weaker and it becomes less dense. Down to 1.120g/cm3 when below 11volts.Checking the acid density will give you an idea of the state of charge.There are 6 cells in a 12v car battery. The charge of each cell should be the same. If the density is significantly different between cells, then that would indicate a fault in that cell and the battery is useless. Faulty cells may have distorted and shorted plates which would stop it being charged and show up with a different density than the other cells.
Why is water used in car radiators?
Water isn't used in car radiators, radiator fluid is. that is used because it is a liquid of the right density to hold radiated heat from the radiator and pass it around the car where it is needed.
Why do you think the drag force on a car depends on the density of air?
