What does mean tells you about a data? The mean is essentially a model of your data set. It is the value that is most common. That is, it is the value that produces the lowest amount of error from all other values in the data set. An important property of the mean is that […]
What happens when liquid changes to solid?
What happens when liquid changes to solid? When a liquid turns into a solid the molecules slow down and begin to vibrate in place. To cause freezing energy must be removed. Because you are removing heat to freeze a substance it is called a exothermic change. The point at which this happens is called the […]
How many ohms of resistance must be present in a circuit?
How many ohms of resistance must be present in a circuit? Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Mathematically given by, R = V/I = 120/10 = 12 ohms or Ω. Which situation will have the highest resistance? the answer […]

What is the dimensionally wrong equation?
What is the dimensionally wrong equation? The dimensionally wrong equations cannot be correct physically because the number of physical quantities themselves willnot be matched regardless of numerical value. 2. A physical quantity has both magnitude and direction. Which formula is dimensionally correct? Pressure = Momentum per unit volume per unit time. Is there an 8th […]

What instrument is used to measure that the air is 21 OC?
What instrument is used to measure that the air is 21 OC? thermometers What is the air pressure in the atmosphere? about 14.7 pounds per square inch How does air pressure affect humans? Barometric pressure is the weight of the atmosphere that surrounds us. Barometric pressure often drops before bad weather. Lower air pressure pushes […]
Can all physical changes be reversed?
Can all physical changes be reversed? Physical changes can further be classified as reversible or irreversible. Physical changes that involve a change of state are all reversible. Other changes of state include vaporization (liquid to gas),freezing (liquid to solid), and condensation (gas to liquid). Dissolving is also a reversible physical change. What are 3 physical […]
