A compass relies on Earth's magnetism to stay pointed north.
A compass works by aligning itself with Earth's magnetic field, allowing users to determine the direction of north.
Kymograph. Don"t ask me how it works- also used to track RF radio frequency waves.
Everything that you plug into the wall works because the electric field is what moves electron from point A to point B. Any optical(mirror, lens, radar ....) device works because of property of light. Light is a EM wave, and most device bend or reflect light by manipulating how the electric field component of the light wave behave.
The mass of the Earth can be determined by the gravitational force it exerts on any object. This works, once the gravitational constant is known. The gravitational constant can be measured with a Cavendish balance.
Copper T is a type of intrauterine device (IUD) that releases copper ions to prevent sperm from fertilizing eggs. The copper creates an inflammatory response in the uterus that is toxic to sperm. This helps to prevent pregnancy by interfering with fertilization and implantation of the egg.
Digital Data is data that is stored in binary, and a Digital Device is any device that works with binary data
A compass works by aligning itself with Earth's magnetic field, allowing users to determine the direction of north.
A Touchscreen Monitor will work as an input and output device
Any digital device - as opposed to an analogue device.
Any electrical device that emits Light
analog
archimedes' principle
Define BJTSRAM?
A router.
A good example of an input and output device is a touchscreen monitor.
A device that works on the idea that something is on or off. In computers 0=off 1=on. The abacus was considered digital because the beads were either on of off.
A downplayer is a rhetorical device that works by attempting to make someone or something less significant or important.
