Did velocity of sound is greater in water than in air?
Yes, the velocity of sound is greater in water than in air because water is denser than air, allowing sound waves to travel more quickly through it.
Which has greater mass 1.0 kilogram of feathers or 1.0 kilogram of lead?
1.0 kilogram of feathers and 1.0 kilogram of lead have the same mass as they both weigh 1.0 kilogram. However, lead is more dense than feathers, so the volume of lead will be much smaller than the volume of feathers.
Why are forcemeter readings are greater in air than in water?
Force meter readings are greater in air than in water because the density of water is higher than that of air. This means that in water, more force is required to displace the water compared to displacing air, resulting in lower force meter readings.
Why the air resistance decrease the acceleration on falling object?
Air resistance applies a force opposite to the direction of motion of a falling object. This force opposes the force of gravity, reducing the net force acting on the object, and hence reducing its acceleration. As the object's speed increases, the air resistance force also increases, further hindering its acceleration.
Which encounters the greater force of air resistance a falling elephant or a falling feather?
A falling elephant encounters a greater force of air resistance than a falling feather does. The force of air resistance can't be greater than the weight of the falling object. When the force of air resistance is equal to the weight of the falling object, the object stops accelerating, its falling speed becomes constant, and the force of air resistance doesn't get any bigger. So the force of air resistance against a falling feather can't be greater than the weight of the feather. But the force of air resistance against a falling elephant can be, and undoubtedly is, greater than the weight of a feather.
How many cc are in a kilogram?
That depends what substance you have a kilogram of.A kilogram of air fills many many cc.A kilogram of water fills only 1,000 cc (1 liter).A kilogram if ice fills a few more cc than a kilogram of water does.A kilogram of lead, gold, or rock fills only a small number of cc.
Is lead more dense than air?
Lead is more dense than air.
Is The air density in Atlanta lesser or greater than the air density in Colorado?
greater
Is the density of air is greater or less than 1?
greater
Why does a kilogram of sand takes up much less space than a kilogram?
A kilogram of sand takes up much less space than a kilogram of feathers because sand is denser than feathers. Density refers to how much mass is contained in a given volume. Since sand particles are heavier and more compact than feathers, they occupy less space for the same mass.
What weighs more lead or air?
lead which is element of non metal is heavier than air
How much volume equals one kilogram?
The volume of one kilogram depends on the density of the material. For water, one kilogram is approximately equal to one liter in volume. However, for other materials with different densities, one kilogram will have a different volume.
Did velocity of sound is greater in water than in air?
Yes, the velocity of sound is greater in water than in air because water is denser than air, allowing sound waves to travel more quickly through it.
When an object or liquid's density is greater than one it wiLL BE WHAT?
The answer will depend on the units used. A density of 1 gram per litre is pretty light (less than the density of air at STP) whereas a density of 1 kilogram per ml is seriously dense.
Why does cold air have a greater volume than hot air?
It does not so there can be no answer to your question.
Is air pressure greater at the top of a mountain than at lower elevations?
No, it is greater at the lower elevations.
How do you find volume if mass is given but density isn't?
You can't. The same mass can have a lot of different volumes, depending on the substance. Examples: A kilogram of stone or lead has a small volume. A kilogram of water has a medium volume. A kilogram of the air inside your house has a large volume.
