Who demonstrated that a small suspended sphere in a vacuum would move toward a large fixed sphere?

Possibly Von Guericke ( pronounced Gerr-eeque) a German scientist and a bit of a showman. He is best known for the Magdeburg Hemispheres (Tug of War) which would not be permissible today due to animal protection laws- unless, say two powerful tractors were used. The Tug of War was in l654 (It Rhymes)

Is James Dyson a Scientist?
Yes. He is an engineer who invented several best-selling vacuum products, including the famous Dyson Ball (not to be confused with Dyson sphere).
A spherical capacitor is formed from two concentric spherical conducting shells separated by vacuum The inner sphere has a radius of ra12.1 cm and the outer sphere has a radius of rb15.0 cm A pot?
dV=E.ds -> C=Q/V=Q/QK[1/r1 - 1/r2] = 4pi epsilon_o [1/r1 - 1/r2]
What is the pressure in a vacuum?
There is no pressure in a vacuum, a vacuum is the absence of anything, there is nothing there to push. Air from a pressurized space that becomes open to a vacuum may push you into the vacuum, but the vacuum itself does nothing as it is literally nothing.
What is the fear of vacuum cleaners called?
vacuum-phobia or vacuum-cleaner-phobia
How can you create a partial vacuum at home?
Turn on the vacuum cleaner, this is a partial or imperfect vacuum.
How does the speed of light change as light change as light moves from a distant star toward earth in the vacuum of space?
As long as it remains in the vacuum in the vacuum, the speed of the light doesn't change at all.
Is a sphere of empty vacuum more buoyant in water than an equal size sphere of air?
When fully submerged on earth, yes. The net buoyancy force will be equal to the weight of the water displaced minus the weight of the object doing the displacing. Because the volume of water displaced by the water will be the same, and presumably have the same weight when the objects are both fully submerged, and the sphere of empty vacuum weighs less than the sphere of air, there will be a greater net upward buoyancy force on each object on earth.
Why is a rain droplet shaped like a pear instead like a ball?
A raindrop would be sphere-shaped if it were floating in space or in the air, but because it does not float, but falls toward the Earth, the raindrop encounters resistance by the air. As the drop passes through the air, the relative motion of the air past the diameter of the spherical drop creates a slight vacuum at the top of the raindrop and that vacuum draws the top of the raindrop upward, creating the Why_are_raindrops_shaped_like_pear_instead_of_a_ballshape.

What is that black sphere with 1 vacuum line in an 89 Chevy s10 engine compartments purpose?
It is a vacuum reservoir to keep the HVAC controls in operation when engine is not producing good vacuum such as under acceleration or climbing long grades. Newer S10's still have one but it is hidden inside the drivers front fender.
Where is the thermostat located on a 2000 VW Sharan 1.9 TDi?
when you remove the engine cover, you see small sphere closest to your alternator. Remove that sphere (vacuum reservoir) and you see outlet pipe from Main radiator. Remove the plastic elbow and you see the thermostat on your engine. Cheers!
Why isn't north always up?
north is a direction horizontally, going along, if you stretched out the earth into a flat ball and walked to the center (north) you would be walking up. if you look at he earth as if its a ball in a vacuum,we cant see outside the vacuum therefore there is not way of telling which way is up in the vacuum, and if we cant say which way up is we cant point to the top of the world, just another point on a sphere in a vacuum.
How long does it take for a 1 km sphere of molten iron to solidify?
To answer the question would require knowledge of several variables that are not specified in the question - to wit: Is "1 km" the diameter, radius, or circumference of the sphere? What is the initial temperature of the sphere? Is the sphere in contact with other matter or is it in a vacuum? Is the sphere under pressure? Does evaporation have to be accounted for? If it is in contact with some other solid, liquid, gas, plasma, etc - what are the physical properties of the material(s) it is in contact with? Is it radiating to a black body? Is there any source of energy radiating back to the sphere? Is the sphere in motion or stationary? Is the sphere subject to any external fields such as magnetic fields? I'm sure we could identify even more unspecified variables that would impact the answer, but the point is that the question cannot be answered without more information.
Where is a Vacuum line diagram for 3.0 liter 1992 Toyota engine?
A diagram should be affixed to the underside of the hood, toward the front, and on the right side.
Where do the vacuum lines hook up to an Edelbrock Performer 2181 intake manifold?
On the sbf windsor manifolds, there is a threaded hole behind(toward rear of manifold) where the carb goes. You will need to screw in a vacuum tree there. As a basic rule of thumb, vacuum lines will always attach to one of the manifold runners that lead to the intake valve(s). Also...pretty much all carbs have vacuum ports. The ones in the base plate are full vacuum, while the ones in the body are usually ported or timed vacuum( like for dist advance).

Where is the egr valve on a 1997 geo prism?
On top of the engine to the right rear of the valve cover is a round plastic unit sort of hat shaped of black plastic with three vacuum hoses coming from it. This is your EGR vacuum modulator. Two hose come out toward the front of the car and one toward the rear and down. Follow this hose and it should go to your EGR valve.
