Answer: Increase in wave frequency
Explanation:
When we talk about acoustics we are dealing with sound waves, and one of their main components along with the velocity and wavelength is the <u>frequency.</u>
In this sense, the frequency of any wave refers to how fast (or slow) a wave oscillates. For example, in the especific case of sound waves when the oscillation is faster, the frequency is higher and the pitch gets higher as well.
Answer:
The decision designer is a step-wise process
Explanation:
A typical decision tree will be like this:
Are there any forces?
YES - then calculate the resultant forces NO - Then no calculations are needed
IF YES - Are the forces balanced? NO - Then no calculations
IF YES - Then calculations can be done.
Resolve the forces to find the resultant of the forces in the question.
A magnetic substance has magnetic fields. These fields start at the North Pole wrap aroundthe magnet, and terminate at the south pole of the magnet. All magnetic substances have <span>north and south poles.</span>
The answer that best completes the statement above is COST-EFFECTIVE ANALYSIS. Occasionally, DUI checkpoints, also known as sobriety checkpoints are being established by police on the roadsides for safety purposes. This is also the same with the seatbelt laws. Both of these aim in decreasing motor-vehicular accidents. Comparing these two, we call it cost-effective analysis. When we say cost-effective, the effectivity of the action if being assessed in relation to the cost it takes to enforce the rule.
