In science, speed is usually represented in meters/second.
In chemistry, the unit "m" is typically used to represent "molarity," which is a measure of the concentration of a solution.
The letter "c" is used to represent the speed of light in a vacuum in physics equations.
None. The speed of light is usually assumed to be constant. The symbol used to represent the speed of light is "C", as in E=MC2. Then why is it called a variable speed?
The unit used to represent electrical pressure is VOLTS.
The definition of unit is that it DOESN'T represent anything. For example: two units of water could be two teaspoons or two gallons. The only thing unit-units are used for is comparing.
The symbol that is used to represent a joule is the letter "J". This is a derived unit of energy. It can also be used to represent work, and an amount of heat.
The definition of unit is that it DOESN'T represent anything. For example: two units of water could be two teaspoons or two gallons. The only thing unit-units are used for is comparing.
speed =distance/speed .units to express speed are m/s and km/hr.
The dimensions of speed are distance/time. Any unit of linear distance and any unit of time may be used.
In order to measure speed, a unit for distance and a unit for time must be used. Common units with which speed is expressed are meters per second (m/s), miles per hour (mph), and kilometers per hour (km/h).
A speed-time graph is used to represent the motion of an object in terms of speed. The speed of the object is plotted on the y-axis, and time on the x-axis. The curve of the graph indicates the acceleration or deceleration of the object.
