Why there is discrepancy between the observed and theoretical frequency in RC oscillator?
The discrepancy between the observed and theoretical frequency in a RC oscillator can arise from several factors, including component tolerances, parasitic capacitances and inductances, and non-ideal behavior of the active components. Additionally, temperature variations can affect resistor and capacitor values, further altering the frequency. The assumptions made in the theoretical model may not fully account for these real-world influences, leading to deviations between the predicted and measured frequencies.

Why values of stresses and strains are different between experimental and theoretical?
The differences in values of stresses and strains between experimental and theoretical results can arise from several factors. Experimental conditions may include imperfections, material inhomogeneities, and environmental influences not accounted for in theoretical models. Additionally, assumptions made in theoretical calculations, such as idealized material behavior or simplified boundary conditions, can lead to discrepancies. Furthermore, measurement errors and limitations in experimental techniques can also contribute to the observed differences.
In a DC suppy the frequency is zero. Why?
Frequency, as regards voltage, is a term applied to changes in the voltage per unit of time. As the voltage of the DC (direct current) supply does not change, it does not "cycle" like an alternating current (AC) supply. The frequency of oscillation of the voltage is zero cycles per second, or zero Hertz.
Ripple marks most likely to be observed in sandstone?
yes
How did Czarnowski form his hypothesis about the flap engines?
Czarnowski formed his hypothesis about the flap engines by analyzing existing aerodynamic principles and performance data from various aircraft designs. He observed inconsistencies in lift generation at different angles of attack and suspected that modifying the flap configurations could enhance efficiency. By conducting theoretical simulations and comparing them with empirical results, he aimed to identify optimal flap designs that would improve overall aircraft performance. This systematic approach allowed him to formulate a well-founded hypothesis regarding flap engine mechanics.
How do pigs make bricks?
No pig has ever been observed making bricks, so their method remains shrouded in mystery.
How do you find absolute discrepancy...this is different from percent discrepancy?
Absolute discrepancy is the absolute difference between an observed value and a theoretical or expected value. To find absolute discrepancy, you simply subtract the observed value from the theoretical value and take the absolute value of the result. This measurement is different from percent discrepancy, which calculates the difference as a percentage of the theoretical value.
What is the frequency for heads in a series of 100 tosses of a fair coin?
The theoretical frequency of heads will be .5 and as you do more and more coin tosses the observed frequency should get closer and closer to .5. With 100 tosses, it will be pretty close, but not exactly .5
Why the observed frequency is greater than the frequency of the source?
The observed frequency can be greater than the frequency of the source due to the Doppler effect, where the relative motion between the source and observer causes a shift in the frequency of the wave. When the source is moving towards the observer, the observed frequency is higher, and when the source is moving away, the observed frequency is lower.
How do you calculate percent discrepancy in physics?
Percent of discrepancy = l observed value - accepted value l / accepted value X 100% note: the two bars around the the observed value - accepted value resemble absolute value signs
What is the difference between empirical and theoretical probability?
Empirical anything is what is observed. Theoretical is a calculation of what things ought to be.
What is the discrepancy formula in physics and how is it used to analyze and quantify differences in experimental data?
The discrepancy formula in physics is used to compare experimental data with theoretical predictions. It calculates the difference between the observed values and the expected values, allowing scientists to quantify how well the data matches the theory. This formula helps researchers identify any inconsistencies or errors in their experiments, leading to a better understanding of the underlying principles.
What's the highest frequency observed in the data set?
The highest frequency observed in the data set is the number that appears most frequently.
A fly buzzes past you at 6m s the frequency of the buzz made by its wings at 162hz assume the speed of sound to be 334 m s what is the observed frequency of the hum as the bumblebee approches you?
As the fly approaches you, the observed frequency of the hum will increase. This is due to the Doppler effect, where the frequency is higher when the source of the sound is moving towards the observer. To calculate the observed frequency, you can use the formula: observed frequency = original frequency x (speed of sound + speed of fly) / (speed of sound).
How do you check for normal distribution?
There are two main methods: theoretical and empirical. Theoretical: Is the random variable the sum (or mean) of a large number of imdependent, identically distributed variables? If so, by the Central Limit Theorem the variable in question is approximately normally distributed. Empirical: there are various goodness-of-fit tests. Two of the better known are the chi-square and the Kolmogorov-Smirnov tests. There are others. These compare the observed values with what might be expected if the distribution were Normal. The greater the discrepancy, the less likely it is that the distribution is Normal, the smaller the discrepancy the more likely that the distribution is Normal.
How do you work out the relative frequency?
The relaive frequency of a particular outcome or event is the number of times the outcome is observed divided by the total number of outcomes observed.
