An accelerometer is a device that uses

Measures acceleration forces.

Explanation: An Accelerometer is a electromechanical device used to measure acceleration forces. Such forces may be static, like the continuous force of gravity. Dynamic to sense movement or vibrations.

Measures acceleration forces.

The motion sensors in accelerometers can even be used to detect earthquakes, and may by used in medical devices such as bionic limbs and other artificial body parts. Several devices, part of the quantified self movement, use accelerometers.

HAVE A GREAT DAY :)

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
