Sound pressure level Sound pressure is the difference, in a given medium, between average local pressure and the pressure in the sound wave.

The airspeed is derived from the difference between the ram air pressure from the pitot tube, or stagnation pressure, and the static pressure.

But, while unilateral pressure can make a difference, the rule of law s defenders must be willing to apply it convincingly.

Certain crystals, such as quartz, or even sugar, generate a potential difference across their faces when subjected to external pressure.

Without an overhaul of the entire judicial system, any government measures or societal pressure are not going to make much of a difference.

Most people do not suffer ill effects up to an altitude of 1800 2500 m (6000 8000 feet), and maintaining cabin pressure at this equivalent altitude significantly reduces the pressure difference and therefore the required hull strength and weight.

To maintain a pressure in the cabin equivalent to an altitude close to sea level would, at a cruising altitude around 10,000 m (33,000 feet), create a pressure difference between inside the aircraft and outside the aircraft that would require greater hull strength and weight.

True implosion usually involves a difference between internal (lower) and external (higher) pressure, or inward and outward forces, that is so large that the structure collapses inward into itself.

All that is lacking is the political will. The mere fact that tapping SDRs requires Congressional approval in the US ensures that nothing will happen without public pressure including pressure from the developing countries. Yet it could make the difference between success and failure in Copenhagen.

that's the difference, that's the difference between us and the dinosaurs.

Spot the difference!

That difference matters.

No difference means no market.

Measurement and units Vapor pressure is measured in the standard units of pressure.

There was no difference whatsoever. And at the Big Bang, what it expanded was the potential for difference.

Diplomatic pressure needed

For a vapor bubble to expand, the temperature must be high enough that the vapor pressure exceeds the ambient pressure (the atmospheric pressure, primarily).

Domestic pressure could very well bring down the regime, but international pressure will not.

Compressed air is air kept under a pressure that is greater than atmospheric pressure.

Ethics Pragmatism sees no fundamental difference between practical and theoretical reason, nor any ontological difference between facts and values.

Tom wouldn't have known the difference.

And that makes all the difference.

Voters need to know the difference.

What a difference a crisis makes.

What a difference a decade makes.

But there is one important difference.

One important, practical difference has emerged.

Dania felt the pressure.
