Tough one. I got the correct answer for the wrong reason. I thought seismometer was either spelled wrong or there was no such word!
Got it, but only thanks to helping my son with earth science last year! Good job, jazz!
Thank you. Glad you liked it.
Having grown up around oil fields I spotted the odd man out immediately. Easy for me. Thanks for contributing.
Got it right away, Yeah
a tachometer measures revolutions per minute..not really the same as "speed"
Sorry Kahlan, but I have to disagree with you.
Tachometer: An Instrument to indicate rotational speed, usually calibrated in RPM (revolutions per minute); an instrument for measuring speed or units.
...or more to the point: A tachometer is a device used for measuring the speed of a moving body or substance (from Greek: tachos = speed, metron = measure).
