This magnetised rod (or magnetic needle) is then placed on a low friction surface to allow it to freely pivot to align itself with the magnetic field.

Most sleds are used on surfaces with low friction, such as snow or ice.

As the wind blows, pressure and friction perturb the equilibrium of the water surface and transfer energy from the air to the water, forming waves.

A solution for this researchers are hoping to find is a low friction coating or channel materials that help reduce the blocking of the tubes.

For example the power of a drill (or any other machine) is proportional to the volume, while the friction of the drill's bearings and gears is proportional to their surface area.

Friction or no friction, OPEC has been, and will always be, irrelevant to market forces on the ground.

The low corona, near the surface of the Sun, has a particle density around 1015 1016 m 3.

(b) An infrared mapping spectrometer with low spatial resolution and high spectral resolution to measure the surface mineralogy.

D0 denotes a critical diameter at which all molecules of a low dimensional glass are located on its surface.

The prospects for friction between EU members escalate.

Communications satellites are typically 1.337 light milliseconds (low earth orbit) to 119.4 light milliseconds (geostationary orbit) from the surface of the Earth.

On December 19, 2000, the spacecraft captured an image of the moon Himalia, but the resolution was too low to show surface details.

Consider the fire that you strike ( and get by friction ) .

The islands are low wetlands, elevated above the lake surface on average by only 1 2 m (maximum 4.5 m) and therefore suffer from floods.

Rob Grover Friction really starts to build up on the spacecraft, and we use the friction when it's flying through the atmosphere to our advantage to slow us down.

Nevertheless, the availability of such technologies has already begun to cause friction.

When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the water cycle.

When seen from a distance, the ocean surface has a low albedo, as do most forests, whereas desert areas have some of the highest albedos among landforms.

His research during and after the war mainly involved investigating surface tension in soap bubbles, rather than further work into the properties of matter at low temperatures.

As on the Internet, so in real life sometimes friction has a purpose.

This is a profound change that creates much friction in the transitional phase.

Similar to surface tension, adsorption is a consequence of surface energy.

Parts and components of liquid propellant surface to air missiles can also be reused in a surface to surface role, like the liquid propellant engines of the SA 2 missiles used in the Samoud 2 surface to surface missiles.

The heavy handed approach adopted by the regime is causing friction among even its loyalists.

The bilateral relationship has been rocky ever since, alternating between periods of friction and conciliation.

Friction or no friction, OPEC has been, and will always be, irrelevant to market forces on the ground. OPEC has never had market power, but Saudi Arabia has, and Saudi market power has always been assigned, mistakenly, to OPEC.

Consolidation is giving way to friction, with more energy needed to overcome the EU s internal problems.

The French worry that NATO s global ambition, particularly in East Asia, could produce friction with China.

But the friction of normal life usually creates ambiguities that cannot be fully met in advance.

A satellite in a low orbit (or low part of an elliptical orbit) moves more quickly with respect to the surface of the planet than a satellite in a higher orbit (or a high part of an elliptical orbit), due to the stronger gravitational attraction closer to the planet.

Friction with the US is thus inevitable, but in the long run there is usually fruitful cooperation.

Many would agree that the root causes of friction among cultures and civilizations are not primarily religious.

But, despite all this diplomatic friction, Wen s entourage for his visit is dominated by a large business delegation.

Of course, there are other sources of friction now that did not seem as pressing five years ago.

While Obama would likely restore civility and politeness to transatlantic discourse, the sources of friction are more profound.

Friction makes the ice at the bottom of the glacier move more slowly than ice at the top.

Finally, surface temperature is used.

Six thousand kilometers below the surface, the planet s core is as hot as the surface of the sun.

The energy of the laser heats the surface of the pellet into a plasma, which explodes off the surface.

First, they were trapped in a vicious circle of low income, low savings and low investment, leading to low productivity and low growth.
