The tape in a cassette-tape deck moves over the head at about 2 inches (about 5.08 cm) per second. A hard-disk platter can spin underneath its head at speeds up to 3,000 inches per second (about 170 mph or 272 kph)! The information on a hard disk is stored in extremely small mag...
speed is measured in miles per hour (mph) or kilometers per hour (kph), but the units physicists most often use for speed are meters per second (m/s). You can get an accurate definition of speed simply by examining
For networks, speed is measured in Mbps or Gbps, as opposed to MPH or KPH, for highways. Staying with Ethernet, Fast Ethernet (an out-dated standard) is 100 Mbps, Gigabit Ethernet is 1000 Mbps, and it goes up from there with newer and newer standards. Like a highway, all lanes must...
A hard-disk platter can spin underneath its head at speeds up to 3,000 inches per second (about 170 mph or 272 kph)! The information on a hard disk is stored in extremely small magnetic domains compared to a cassette tape's. The size of these domains is made possible by the precision...
meaning wind. The earliest description of an anemometer was in 1450 by an Italian architect, artist, and authorLeon Battista Alberti. An anemometer is an instrument that measureswind speedand wind pressure. Anemometers report wind speed in miles per hour (mph), kilometers per hour (kph), mete...
The speed limit on some interstate highways is roughly 120 km/h. What is this in meters per second? How to convert kph to mph with a formula A car is traveling at a speed of 8 m/s. It accelerates to a speed of 11 m/s in 7 seconds. Calculate the (a) acceleration of the...

Moving at up to 5 mph (8 kph) in Reverse (R) How Do I Use Trail Control With My Ford Vehicle? To switch Trail Control on and off, all you have to do is press the Trail Control button located on your console (top left buttons surrounding the G.O.A.T. Modes™ dial). The sys...
The SI (international) units for velocity are m/s (meters per second), but velocity may also be expressed in any units of distance per time. Other units include miles per hour (mph), kilometers per hour (kph), and kilometers per second (km/s). ...
An airplane goes from 0 to 220 mph in 30 seconds on a runway to take off. Assuming constant acceleration, how far down the runway does the plane travel before take-off? When an aircraft returns to the aircraft carrier and lands, it ...
