How did the actual results of rutherfords gold foil experiments differ from the results he expected?
Rutherford expected that the alpha particles would pass through the gold foil with only minor deflections. However, some alpha particles were deflected at large angles, and a few even bounced back. This result led Rutherford to propose the existence of a small, positively charged nucleus at the center of the atom.
What else can I help you with?
How did Rutherford's actual results differ from the expected results?
Rutherford's actual results from the gold foil experiment showed that the majority of alpha particles passed straight through the foil with some being deflected at large angles or even reflected back. This was unexpected as it contradicted the prevailing model of the atom as a solid sphere. The unexpected deflections led to the proposal of the nuclear model of the atom with a small, dense nucleus at the center.
What causes float?
Floating point errors can occur due to the limitations of representing real numbers in computers with finite precision. This can lead to rounding errors when performing calculations involving real numbers, resulting in small discrepancies between the expected and actual results.
How can you calculate interference factor?
The interference factor can be calculated by dividing the observed frequency of double crossovers by the expected frequency of double crossovers. This value represents how much the actual frequency deviates from the expected frequency due to interference.
Is time dilation is apparent or actual change?
Time dilation is an actual change in the passage of time due to the relative motion between two observers. It has been confirmed through various experiments and is a fundamental prediction of Einstein's theory of relativity.
Which term describes how close measurements are to the actual value?
Accuracy describes how close measurements are to the actual value. It is a measure of how well the results agree with the true value of the quantity being measured.
Do the actual results deviate from what was expected If so explain how?
whats the meaning accurately expected results and actual results
What term is used to describe the process of monitoring operating results and comparing actual results with the expected results?
This process is known as performance monitoring or performance evaluation. It involves analyzing actual operating results against planned or expected results to assess the efficiency and effectiveness of business operations.
When WHAT comcare actual findings to expected results determine if your current programs are accomplishing goals?
D. Interpreting Results
How do you compute the percent error or formula?
Actual results divided by your expected results. Subtract that number from 1. Multiply that by 100. For example: Actual result : 9 grams Expected result: 10 grams 9/10 = .9 1 - .9 = .1 .1 x 100 = 10 10% error.
Are expected results due to chance or are they arrived at mathematically?
Expected results can arise from both chance and mathematical calculations. In probabilistic contexts, expected values are calculated using mathematical formulas based on probabilities and outcomes. However, in experimental settings, observed results may also reflect random variations or chance. Therefore, while mathematical methods provide a framework for predicting expected results, actual outcomes can be influenced by stochastic factors.
What does it mean if you get a negative number when you calculate for percent error?
Depending on whether you subtract actual value from expected value or other way around, a positive or negative percent error, will tell you on which side of the expected value that your actual value is. For example, suppose your expected value is 24, and your actual value is 24.3 then if you do the following calculation to figure percent error:[percent error] = (actual value - expected value)/(actual value) - 1 --> then convert to percent.So you have (24.3 - 24)/24 -1 = .0125 --> 1.25%, which tells me the actual is higher than the expected. If instead, you subtracted the actual from the expected, then you would get a negative 1.25%, but your actual is still greater than the expected. My preference is to subtract the expected from the actual. That way a positive error tells you the actual is greater than expected, and a negative percent error tells you that the actual is less than the expected.
Accuracy is a measure of how close an answer is the actual or expected value true or false?
True. Accuracy refers to the degree to which a measured or calculated value aligns with the true or expected value. It assesses the correctness of the results in relation to the actual standard or benchmark. Therefore, a higher accuracy indicates a closer match to the true value.
What is experience gain or loss in acturial valuation?
In actuarial valuation, experience gain or loss refers to the difference between the actual experience of a group of policyholders (such as mortality rates) and the expected experience based on the assumptions used in the valuation. If the actual experience is better than expected, it results in experience gain, and if it is worse, it leads to experience loss. These gains or losses impact the financial results and reserves of an insurance company.
What is a expected result?
An expected result refers to the anticipated outcome of a specific action, experiment, or process based on prior knowledge, theories, or data. It serves as a benchmark against which actual results can be compared to evaluate effectiveness or accuracy. In scientific research, expected results help guide hypotheses and inform interpretations of data. Ultimately, they assist in understanding whether a particular approach or intervention achieves the desired effect.
Precision is a measure of how close an answer is to the actual or expected?
False
