Answer: sound can slow down, so when it travels through all of that it's muffled and kind of blocked. sound travels at 332 metres per second so it's hard to stop the sound
Explanation:
<span>This is an example of a substance changing state, a physical change, the molecules are changed, but the atoms themselves do not change, just their arrangement, and the mass of the molecules is the same. Therefor energy is absorbed by the molecules, as energy is required to change the state or physicality of a molecule structure.Hope this helps. Let me know if you need additional help!</span>
<span>Both plants and animals fight pathogens is because both have an ant. </span><span>The answer is B.

ANSWER: The two skills that Wade will need to excel in the career of a Radiologist are:
1. Interpersonal skills to talk to patients and help them feel comfortable: This skill important because patients often are afraid of getting detected by a disease. Few patients also fear of getting tested by the heavy and complicated machineries. A radiologist's interpersonal skill will calm the patient and his attendant and will make them feel relieved.
2. Technical skills to know how to use the machinery and equipment needed for the job: Radiologist's primary duty is to operate the machineries in order to diagnose a patient correctly. A radiologist can not afford to be an amateur as he will either not be able to detect a disease or may raise a false alarm of a person having a disease.

Explanation:
Dimensional analysis is useful whenever dimensions are involved. Unless it is quite clear that all of the problem dimensions are consistent (for example, all speeds in miles per hour, or all angles in degrees), dimensional analysis can be useful for keeping the math straight.
Only units of the same dimensions can be added or subtracted. When numbers are multiplied or divided or raised to a power, dimensional analysis can help ensure that the appropriate operations are being used on appropriate numbers. It can also help ensure that dimensions are being combined properly to give appropriate derived dimensions.

Scientific notation is a way of writing very large or very small numbers compactly. It can also help with "order of magnitude" estimates. If an answer using SI prefixes is appropriate, or if a number can be conveniently expressed in standard form, then scientific notation is usually not required.
On the other hand, SI prefixes may not be appropriate in some cases, or a problem may specify that scientific notation be used for expressing results. In those instances, scientific notation should be used.
