# Does a larger sphere have a higher terminal velocity?

No it would have a lower terminal velocity as there would be more air resistance acting upon it

### Does the mass of falling object effect the speed of which it falls?

No, mass does not have an effect on a falling object, as long as the object is falling in a vacuum. If an object is falling through air, then aerodynamics come into play. For example, a 1' solid steel sphere will reach a higher terminal velocity than a 1' polished wood sphere.

### Why different sized metal spheres used in determining the coefficient of viscosity of oil?

as according to stoke's law the terminal velocity depends upon the radius of the metal sphere.

### Why velocity of big shpere in viscous liquid is higher than small shpere?

It is because the bigger sphere is bigger.

### What is the magnitude of net force acting on a drop of rain falling down with a constant speed?

consider a sphere moving through a viscous medium the fluid layer in contact with the sphere is moving with same velocity but the layer far away is at rest. This makes a relative motion to be setup.viscous force acts on this drop.The backward force is proportional to the speed of the drop.at a stage the viscous force balances the downward force.hence the body moves with a constant velocity called terminal velocity.

### How fast can hail fall?

How fast does hail fall? We really only have estimates about the speed hail falls. One estimate is that a 1cm hailstone falls at 9 m/s, and an 8cm stone, weighing .7kg falls at 48 m/s (171 km/h). However, the hailstone is not likely to reach terminal velocity due to friction, collisions with other hailstones or raindrops, wind, the viscosity of the wind, and melting. Also, the formula to calculate terminal velocity is based on… Read More

### Two spheres of the same diameter but of different mass are dropped from the tower If air resistance is the same for both which will reach the ground first Why?

The sphere with more mass will reach the ground first because it has more inertia and it's speed and acceleration are less affected by the resistance caused by the air (it also has a higher terminal velocity). If dropped in a vacuum, however, they would both accelerate at the same speed and hit the ground simultaneously.

### Can a magnet's strength and sphere of influence have independent values?

Independent of what? A stronger magnet will obviously have a larger "sphere of influence".

### Suppose the sphere below with radius r has a surface area equal to 45 units 2 Find the surface area of the sphere with twice the radius'?

The area of a sphere is given by the formula A = 4πr² A sphere with radius r has an area = 4πr² A sphere with radius 2r has an area = 4π(2r)² = 4π.4r² = 16πr² The ratio of the larger sphere to the smaller = 16πr² : 4πr² = 4 : 1 If the area of the smaller sphere is 45 units then the area of the larger sphere is 45 x 4… Read More

### How is the coeefficientof viscosityof oil determined?

by dropping different sized small metal sphere and determining its terminal velocity.(using Stoke's law) also by Poisseulli's experiment and formula : Volume of liquid flowing throurgh a narrow pipe per second=Pressure difference*Pi*(radius of the pipe)4/8* coefficient of viscosity*length of the tube.

### What is the role of altitude for a black hole?

The escape velocity is affected by altitude for any celestial body; the further away from the mass, the lower the escape velocity from that point. At the event horizon, the escape velocity is the speed of light. Within the photon sphere but outside the event horizon, light paths not pointing outward will intersect the event horizon. At the photon sphere, a notionally tangential light beam would ideally remain in a perfectly circular "orbit" around the… Read More

### What force makes a feather fall slowly to the earth?

This is due to the force of viscosity, or better understood as air friction. It is the reason that any object will eventually stop speeding up and reach a terminal velocity. This viscosity force is often described as an expansion: F= av + bv^2 + c v^3 and so forth. Often this is approximated and the only term used is av. For a sphere falling under streamline conditions a=6*pi*viscosity*radius of the sphere. Hope that helps.

### Do objects of the same mass but of different shapes fall at the same velocity?

No.For example a sphere will fall faster than a cube.

### Why in coulomb's law for charges force is inversely proportional to square of distance between charges?

Imagine a light bulb in the center of a sphere. It emits a fixed quantity of light. That's how much light will reach the sphere. The concentration of light per unit of area, on the sphere, will depend upon how large the sphere is. And the area of a sphere is proportional to the square of the radius of the sphere. So the intensity of the light will be inversely proportional to the square of… Read More

### What is the schwarzschild raduis?

The Schwarzschild radius is a concept related to black holes. Given a body it is the radius such that, if all the mass of the body were squeezed (uniformly) within that sphere, then the escape velocity at the surface of the velocity would be equal to the speed of light.

### What happens when the volume of the sphere is doubled to the total flux through a spherical gaussian surface surrounding a point charge?

You then have an imaginary sphere with twice the volume of the one you imagined only moments earlier. If the point charge is anywhere inside the smaller sphere, and the smaller sphere is anywhere inside the larger one, then the total flux is the same through each of them, although the average flux density through the larger one is less than the average flux density through the smaller one.

### What is the scale factor of spheres with a radius of 12 and 4?

Assuming the smaller sphere is the image of the larger sphere after transformation (based on the order of the radii): the scale factor is 4/12 = 1/3

### If you have a cube and a sphere that weigh the same but only the cube will float what does that tell you about the volume?

The cube has a larger volume.

### Will asolid metal sphere hold a larger electric charge than a hollow sphere of the same diameter where does the charge reside in esch case?

The charge all resides on the surface of the sphere, whether or not there's anything inside the surface. In principle, there's no limit on the amount of charge that can be jammed onto the sphere. The only limit is a practical one, that is, how much charge you can move and transfer to the sphere before it starts arcing back to the machinery or the support that's holding it.

### What happens when you bury a sphere in pokemon platinum?

If you leave them long enough they will grow to larger sphere's the underground man should explain that.

### Do objects fall at the same speed through water?

No. The speed an object will fall in water depends on: 1) The mass of the object compared to the volume of water displaced 2) The hydrodynamic friction between the water and the objects motion 3) The local gravity. For example: A 10cm sphere of iron has a density of 7.8 and a mass of 4.08kg. The mass of water displaced is 0.52kg. Gravity exerts a downward force of 40.0N downwards on the sphere, while… Read More

### Why all spheres are similar?

By definition all spheres are identical in shape because a sphere is perfectly round. That's what "sphere" means. In the same way, all perfect squares are identical and all equilateral triangles are identical. Spheres might be larger or smaller, but the shape of all is the same because there is only one kind of sphere.

### How do I solve this calculus problem regarding drag force and gravity?

I'm having trouble finding the relation between velocity and time given this formula. If anyone has a solve for this, It would be great if you took your time to help me as I know this includes differential acceleration, which requires calculus.

### When does riolu learn arua sphrere in Pokemon mystery dungeon exploreres of sky?

Riolu does not learn "Aura Sphere", as it is not in its learnset. To get Riolu to learn "Aura Sphere", you must evolve it into Lucario. Lucario learns Aura Sphere sometime in level 30-40. If you are higher than that, simply go to Electivire Link Shop

### If a rock is dropped into awell that 340 feet deep how many seconds will it take for the rock to hit the bottom?

This problem is difficult to answer without more information. Is the well filled with water? If so then you must know the size of the rock and the shape of the rock to calculate the affect of buoyancy and friction due to viscosity. If you assume the rock is dropping through air the only force is that of gravity. Therefore you can use the acceleration due to gravity and the following equation: D= Vinitial*t +(1/2)g*t^2… Read More

### What is the equation for the scale factor of a sphere?

There is no equation for the "scale factor" of a sphere. If I assume you to mean how the volume increases with radius then you would use the volume equation for a sphere and calculate volume based on corresponding radii. You could then divide the resultant volumes to give a percentage or factor of how much larger or small one sphere is than another. You'll see that a small change in radius causes a large… Read More

### If a sphere of dia 3 cm is melted and formed into 3 spheres the diameter of 1st is 1.5cm and that of second is 2.0 cm what is the diameter of the third?

The answer is 2.87 cm. Use the formula to find the volume of a sphere: V= (4/3) * Pi * r^3 Find the volume of a sphere that has a 3 cm radius, then find the volume of a sphere with a 1.5 cm radius. Subtract the volume of the smaller radius from the volume with the larger radius. The answer will give you the remaining volume of the larger sphere. You can plug it… Read More

### Which is larger - the Northern or Southern Hemisphere?

They are of approximately equal size depending on the measurement. Hemisphere, meaning "half sphere" refers in this case to dividing the Earth exactly in half. The Earth itself though isn't a sphere; it's an oblate spheriod. So minor differences may exist.

### What will be the weight of a model plane which is 1 is to 400 in scale and the real plane weighing at 500 tons and the formula by which you calculated this?

Someone may come along with a better answer than this but I would rather keep things simple. If you are to assume that the 1 to 400 model plane is the exact same density (mass/volume) as the real plane which weighs 500 tonnes or 500 000 kg. You take the scale of 400 and cube it 4003 or 400X400X400=64 000 000 this number represents how many model planes would fit into the real plane if… Read More

Let, Coefficient of viscosity of liquid = eta Radius of sphere = a velocity of sperical body = v Dimensionally it can be proved that F = k eta*a*v Experimentally Stoke found that k = 6*pi therefore, F = 6*pi*eta*a*v This is Stoke's law.

### Why do sounds get quieter the further away you are from the source?

Louder or fainter means more intense or less intense of sound vibrations respectively. Intensity in turn is the energy per unit area. Imagine the source of sound to be at the centre of a sphere. When you are far away then the radius of the sphere would be larger and thus the surface area of the sphere also becomes larger. As the energy given out by the source of sound is divided by larger area… Read More
