The most ancient and well known is the sundial. Sundials have existed for thousands of years.
Another method was the graduated candle. A candle of a known composition and thickness was marked into divisions and lit. By sitting the candle in a metal bowl and sticking a nail in at a certain point, a timing device or alarm clock could be created.
The dripping of water at a steady rate between two vessels was another early method of measuring time.
These two latter methods could be calibrated accurately by marking them in daylight whilst sitting next to a sundial.
The Chinese were the first people to create a machine that could measure elapsed time by the controlled release of a spring or weight. Likewise the machine could be calibrated in daylight and would then render accurate time throughout the night.

Give at least 10 physical quantities and their units?
Write about 10 instruments which are used to measure different physical quantities i.e. - mass, volume, time and temperature
How time calculated?
time=distancedividedby speedbecause speed= distance divided by time and distance= speed*time
What is the instrument used to find density?
Any instruments that can measure mass and length. (not at the same time, doesnt have to be the same instrument). By measuring the length, height and width of an object you can determine it's volume and by weighing it you can determine it's mass. From these results it's possible to calculate the objects density.
Is time a label position measure or count?
Measure
In which unit did early cultures measure time?
in early times,people measured thing with their body parts.for example hand span.
How did ancient people measure time?

What is the metric unit for time and what instrument do you use to measure temperature?
Unit for time is a second.There are various instruments to measure temperature: a thermometer, a thermocouple are two.
Why did people use hourglasses?

Name the instruments necessary to measure each of the above quantities which are known by the units which they measure?
To measure various physical quantities, different instruments are used based on the type of quantity being measured. Here are some examples: Length: Measured in meters (m). Instruments used to measure length include rulers, tape measures, and calipers. Mass: Measured in kilograms (kg). Instruments used to measure mass include balances and scales. Time: Measured in seconds (s). Instruments used to measure time include clocks and stopwatches. Temperature: Measured in degrees Celsius (°C) or degrees Fahrenheit (°F). Instruments used to measure temperature include thermometers. Electric current: Measured in amperes (A). Instruments used to measure electric current include ammeters. Voltage: Measured in volts (V). Instruments used to measure voltage include voltmeters. Frequency: Measured in hertz (Hz). Instruments used to measure frequency include oscilloscopes and frequency counters. Pressure: Measured in pascals (Pa). Instruments used to measure pressure include barometers and manometers. There are many other physical quantities that can be measured, and different instruments may be used depending on the specific quantity and the required precision of the measurement.
