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.

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.
Why is the actual speed of a car not usually the same as its average speed?
The actual speed of a car can vary due to factors such as traffic congestion, traffic signals, road conditions, and weather conditions. Average speed is calculated by dividing total distance traveled by total time taken, whereas actual speed is the speed at any given moment. So, fluctuations in actual speed can cause it to differ from the average speed.
How does an ideal machine differ from actual machine?
An ideal machine operates without any energy losses, friction, or other inefficiencies, providing 100% efficiency at all times. In contrast, an actual machine experiences energy losses due to factors such as friction, heat, and inefficiencies in its components, resulting in less than 100% efficiency in its operation.
Why does the theoretical flow rate differ from the actual flow rate?
Theoretical flow rate is based on ideal conditions and perfect characteristics of the system, while actual flow rate considers real-world factors such as friction, turbulence, and imperfections in the system components. These factors can cause deviations between the theoretical and actual flow rates due to losses in pressure, flow restrictions, and other inefficiencies in the system.
Does the intensity of Xrays and gamma rays differ?
Yes, the intensity of X-rays and gamma rays can differ. Gamma rays typically have higher frequencies and energies than X-rays, so they can be more penetrating and have a higher intensity. However, the actual intensity of these radiation types depends on factors such as the source strength and distance from the source.

In your simulated two factor cross why might your actual experimental values have been different from the values you expected?
Actual values might differ from expected values in a two-factor cross due to genetic linkage, where two loci are located close together on the same chromosome and do not assort independently. Another reason could be the influence of environmental factors on the expression of traits. Lastly, errors in data collection or analysis could also lead to discrepancies between actual and expected values.
Why does the expected genotypic ratio often differ from the expected genotypic ratio resulting from a monohybrid cross?
becouse you touch yourself at night.
Why does the expected genotypic ratio often differ from the expected phenotypic ratio from monohybrid cross?
Because in heterozygotes, both alleles are transcribed and translated.
Why does the normality of sodium hydroxide change?
Because of water's nature to partially ionise itslef into hydronium and hydroxide ions, any solution of either a hydroxide or an acid will always be affected by this tendency, making the actual concentrations differ slightly from the expected ones.
How does acceracy differ from precision in scientific measurement?
Accuracy refers to how close the results are to the established (or predicted) values. Experimentally, accurate results are evidence that the procedure worked as expected and that the combined error from all sources (instrumental, environmental, and human) is low. Precision refers to how close the results are to each other. Highly precise results will indicate that the experiment was run (nearly) identically each time, though it will not guarantee accuracy.
When is volume variance nonzero?
Volume variance is nonzero when there is a difference between the actual level of production achieved and the expected or budgeted level of production. This occurs when actual sales volume deviates from the planned sales volume, leading to changes in fixed costs allocated per unit. If the actual output is greater or less than what was anticipated, the fixed costs per unit will differ, resulting in a volume variance.
How many Gregorian calendar years differ from actual solar years?
All of them
Mendeleev's predicted an atomic mass for the element that was later discovered and named germanium how much does germanium actual atomic mass differ from his prediction?
Mendeleev predicted the atomic mass of germanium to be approximately 68 g/mol. The actual atomic mass of germanium is about 72.63 g/mol. This results in a difference of roughly 4.63 g/mol between Mendeleev's prediction and the actual value.
If some measurements agree closely but differ widely from the actual value?
Then they have precision but not accuracy.
How does actual texture differ from simulated yexture?
Actual texture has real surface quality... It has a bit of relief... You can feel actual texture with your fingertips. Simulated texture is just that... simulated. It is two dimensional.
How did the reality of the Great War differ from the expectations at the beginning of the war?
The war was going to last longer than people expected.
