A formula unit is the smallest ratio between atoms of different elements in this kind of structure that can be expressed as whole numbers. Ionic Compounds A simple example is sodium chloride, or common salt, a compound of the elements sodium and chlorine. A salt crystal consists of positively...
For example, sodium chloride, more commonly known as table salt, can be expressed by the formula unit NaCl. Regardless of how many ions of sodium chloride are being used in a chemical equation, the formula unit for sodium chloride is the simplified expression of one sodium atom to one chlori...

The magnitude of the electric field is given by the formula E = F/q, where E is the strength of the electric field, F is the electric force, and q is the test charge that is being used to “feel” the electric field. Example: Electric Field of 2 Point Charges For two point charg...
Give an example of a derived unit. How does a quantity differ from a unit? What is the unit of work? Define motor unit. What is the SI unit of mass? What is the SI unit for speed? What is the metric unit for length? What is the unit of specific gravity?
'Millimeter' is a unit of length that equals one-thousandth of a meter. It is a small unit of measurement.
Learning Curve Formula The learning curve has a formula to identify a target cumulative average time per unit or batch. The formula for the learning curve is: Y=aXbwhere:Y=Cumulative average time per unit or batcha=Time taken to produce initial quantityX=The cumulative units of production or...
Example: Suppose that a car travels from point A to point B in half an hour. If the distance between A and B is 2 miles, what was the speed of the car?Distance = 2 milesTime taken = 0.5 hourSpeed $= \frac{Distance}{Time} = \frac{2}{0.5} = 4$ miles per hour...
You can use the advanced formula when you don’t know the total variable costs. Here, you have to replace the total variable cost with the average variable cost multiplied by the total units produced. Example #2: UltraSpeed Ltd. is a company that manufactures automotive components. As per ...
Torque is the twisting force that tends to cause rotation. It is the measure of how much a force acting on an object causes that object to rotate. Visit to learn how to calculate torque along with its formula, meaning and applications.
