The Canadarm (technically called the Shuttle Remote Manipulator System) is used to lift and manipulate satellites, parts, and other equipment from the payload bay of the shuttles to their correct position. It is also sometimes used to move an astronaut to another part of the outside of the space station or shuttle.
A bobbin is a device which holds the thread that is below the needle in a sewing machine. The shuttle is a (usually) removable housing the bobbin is inserted into.

He discovered the female pleasure device, when one day he slipped with his candle stick and it penetrated his butt.
Mendeleev. Many others contributed ideas before bu Mendeleev's contribution is considered the most important.
The accuracy of the measurement device determines the number of significant figures that should be retained in recording measurements.

A space probe is an unmanned device that is sent into space for purposes of exploration. The space shuttle is a manned vehicle meant for research and delivering supplies, equipment, and people into low-Earth orbit.
Rube Goldberg was not a scientist, he was a humorist. He devised insanely impractical devices to amuse the public. To this day, any device that does something relatively simple (cracking an egg, for example) in a ridiculously complicated way, can be called a Rube Goldberg device.
The accuracy of the measurement device determines the number of significant figures that should be retained in recording measurements.
significant digits. for short they are called "sig. figs."
0.48 has 2 significant figures and 0.4800 has 4 significant figures. The correct answer would depend on the device used to measure the string, and on the precision of that instrument.
You would need to record to the 0.1 cm, then estimate the next significant figure. So you should have a measurement to the 0.01 cm.
