- How to determine the volume of a room using a long thin thread, a stopwatch and a hundred-gram weight?
- How to determine the volume of a room by placing a một of copper wire, a scale with a set of weights, a battery, a voltmeter and an ammermeter?
- At street intersections in some cities, electric devices are installed that automatically calculate and display on a light display the speed that automated vehicle drivers must maintain in order to approach the next traffic light under the green light. Generally, the display readings change in the following sequence: first 45 km/h, then 50 km/h and finally 60 km/h. After this, the sign usually goes out, since speeds over 60 km/h are allowed only on a small number of streets.
How can you determine the distance to the next traffic light by watching the board readings using only a watch?
