Across
- 1. an enclosed space from which matter, especially air, has been partially removed so that the matter or gas remaining in the space exerts less pressure than the atmosphere
- 5. the portion of space near a magnetic body or a current-carrying body in which the magnetic forces due to the body or current can be detected
- 6. something that causes a change in the motion of an object.
- 7. a tube with a nozzle and piston or bulb for sucking in and ejecting liquid in a thin stream,
- 9. he departure of an indicator or pointer from the zero reading on the scale of an instrument.
- 10. collapse or cause to collapse violently inward
- 11. an instrument or device for measuring the amount or magnitude of something
- 13. a mechanism that uses the resistance offered or the pressure transmitted when a liquid is forced through a small opening or tube
- 15. = F / A
- 16. machine that converts one form of energy into mechanical energy and so causes motion;
Down
- 2. an instrument for measuring the pressure acting on a column of fluid, especially one with a U-shaped tube of liquid.
- 3. energy in an object due to its motion
- 4. flow of electrons
- 8. of or relating to or using air
- 12. cause (something) to pass on from one place or person to another
- 14. a tube used to convey liquid upwards from a reservoir and then down to a lower level of its own accord. Once the liquid has been forced into the tube, typically by suction or immersion, flow continues unaided.
