pressure = 1/3* density * mean square speed
and
ke = 1/2*m*m.s speed
and
ke = 1/2*m*m.s speed
This is because different formulae may take into account different variables or use different methods of calculation, leading to variations in the result. Additionally, rounding errors and experimental limitations can also contribute to the differences.
The formula to use depends on the specific situation and what variables are being measured. It is important to carefully analyze the data and determine which formula is most appropriate for the given scenario.
Yes, for example, the formula for calculating the r.m.s of a set of numbers is different from the formula for calculating the r.m.s of a set of velocities. The former uses the sum of squares while the latter uses the square root of the average of squares.
Experimental limitations, such as measurement errors or uncertainties, can affect the accuracy of the r.m.s calculation by introducing variations in the data. These limitations should be taken into account and minimized as much as possible to improve the accuracy of the result.
Yes, there may be certain assumptions involved in using the formula for r.m.s, such as assuming a normal distribution of data or assuming that the measurements are independent. It is important to understand these assumptions and ensure they are valid for the given situation to obtain accurate results.
