The fake sound you hear when you have tinnitus. Also, any device that is permanently on will produce a constant sound.
A bronsted-lowry acid is a useful device for measuring this sort of radiation.
If drag and thrust are equal, a flying device will stop ACCELERATING, that is it will maintain a constant speed.From classical Newtonian physics:Force = mass x accelerationSince drag and thrust are forces, we have:Thrust - drag = mass x accelerationSince you say that drag and thrust are equal, and the mass of a flying object is some finite value, it turns out that the acceleration = 0, i.e. a constant speed
A gas thermometer is a device that measures temperature by the variation in volume or pressure of a gas. It is made by filling a bulb with gas such that the volume of the gas in the bulb remains constant.
Simply by measuring the time it takes for the sonar 'ping' to return to the device that sent it. The speed of sound is constant - and dividing the time by the speed of sound gives the distance !

A barostat is a device used to maintain a constant atmospheric pressure.
No, it has to be an alternating current in order to work
