There are several potential sources of error that could explain differences between a predicted sound speed and the experimentally measured value. Some common sources of error include:
1. Instrumental Errors: Inaccuracies or limitations in the measurement instruments used to determine the sound speed. This could include issues with the calibration of the instruments, sensitivity limitations, or errors in reading the measurements.
2. Environmental Factors: Variations in temperature, humidity, and atmospheric conditions can affect the speed of sound. If these factors are not accounted for or if they fluctuate during the experiment, they can introduce errors in the measured value.
3. Experimental Setup: Mistakes or inaccuracies in the experimental setup can lead to discrepancies between predicted and measured values. This could involve errors in the positioning of the sound source and receiver, incorrect timing measurements, or improper alignment of the equipment.
4. Assumptions and Models: Simplifications or assumptions made in the theoretical prediction of sound speed can introduce errors. If the underlying physics or properties of the medium are not accurately accounted for, the predicted value may deviate from the experimental measurement.
5. Human Error: Errors or biases introduced by the experimenter during the measurement process, such as misinterpretation of data, incorrect calculations, or systematic errors in data collection or analysis.
It is important to identify and minimize these sources of error through careful experimental design, calibration, and repeated measurements. Additionally, conducting experiments in controlled conditions and using precise measurement techniques can help reduce uncertainties and improve the accuracy of the measured sound speed.

B.the amount of space that matter ocupies
C.how fast the particles are moving
D.amount of massin a certain place
B) they would not be able to see anything outside the window.
C) lasers can not be transmitted through the vacuum of space.
D) the sound of the explosion would not be transmitted back to their ship.
Answer:
D. the sound of the explosion would not be transmitted back to their ship.
Explanation:
Sound is a type of mechanical wave so it needs a solid to move through. Since space is a vacuum, the Klingon crew would not be able to hear the explosion.
Answer:

Answer:
A) Bohr’s work with atomic spectra led him to say that the electrons were limited to existing in certain energy levels, like standing on the rungs of a ladder.
Explanation:
The change to the atomic model that helped solve the problem seen in Rutherford's model was the discovery of the strong nuclear force.
Rutherford's model required that the electrons be in motion. Positive and negative charges attract each other, so stationary electrons would fall into the positive nucleus. However, Rutherford's model failed to explain why electrons were not pulled into the atomic nucleus by this attraction. The change to the atomic model that helped solve this problem was the discovery of the strong nuclear force, which is much stronger than electrostatic interactions and holds the protons and neutrons together in the nucleus.
