Which of the following measurements is not a unit of distance?
A. Ammeter
B. Cubit
C. Parsec
D. angstrom
Answers
Answer:
A) Ammeter
Explanation:
A) Ammeter
An instrument used to measure the current in a circuit is called an ammeter (short for ampere metre). Amperes (A) are the units used to measure electric current. The ammeter is typically linked in series with the circuit that will be used to measure the current. A typical ammeter has a low resistance so that it won't significantly lower the voltage in the circuit being measured.
Microammeters and milliammeters are terms used to describe devices that measure currents in the milliampere or microampere range. The Earth's magnetic field was necessary for the operation of the earliest ammeters, which were laboratory instruments. In a circuit, it is typically symbolised by the letter "A."
B) Cubit
The cubit is a historic measurement of length based on the distance between the elbow and the middle finger's tip. It was mostly connected to the Israelites, Egyptians, and Sumerians. The Bible uses the word "cubit" in reference to Noah's Ark, the Ark of the Covenant, the Tabernacle, and Solomon's Temple. The common cubit was divided into 24 digits, or six palms and four fingers.
Ancient Antiquity, the Middle Ages, and even the early modern era saw the use of cubits in many different places of the world. The phrase is still used in hedgelaying, where the distance between stakes is typically calculated based on the length of the forearm.
C) Parsec
The parsec (symbol: pc) is a measurement unit for astronomical distances outside of our solar system that is roughly equivalent to 3.26 light-years or 206,000 astronomical units (au), or 30.9 trillion kilometres (19.2 trillion miles). it is calculated using parallax and trigonometry. Proxima Centauri, the closest star, is 4.2 light years (or 1.3 parsecs) away from the Sun. Nearly all stars that can be seen with the unaided eye are located within a few hundred parsecs of the
D) Angstrom
The angstrom, is a metric unit of length equal to m, or one ten-billionth (US) of a metre, one hundred millionth of a centimetre, one nanometer, or one hundred picometres. The component carries Anders Jonas Angström's name, a Swedish physicist (1814–1874).
