2.78 X 10^5 is the best answer to be responded to
Answer:
Sin(60°)=
Explanation:
Assuming the given angles are in degrees
We know that Sin(A-B)=SinACosB-CosASinB
Here A=100° and B=40°
Answer:
A) As the ambulance's siren moves toward a stationary hearer, the quality of sound will have a higher pitch
B) As the ambulance's siren moves away from a stationary hearer, the quality of sound will have a lower pitch.
Explanation:
From Doppler effect, the closer the source of sound gets to the observer, the higher the frequency and in turn the higher the pitch.
Meanwhile, the farther a source goes from an observer, the lower the frequency of the sound and also the lower the pitch.
Thus, as the ambulance's siren moves toward a stationary hearer, the quality of sound will have a higher pitch.
As the ambulance's siren moves away from a stationary hearer, the quality of sound will have a lower pitch.
I believe C is the answer
Hope this helps you have a great night!!
Good luck
Answer:
The three components of effective communication are:
- Sending Communication
- Receiving Communication
- Feedback
Explanation:
<h3>1) Sending Communication</h3>
One should think about what he is going to say, structure his message and focus clearly on a the purpose of sending a message. For example if an employer wants to communicate an employee to improve his performance, he should focus hid communication on the results rather than on his failures.
<h3 /><h3>2) Receiving Communication</h3>
The person on the other end of the communication should be a good listener. For example in the example given, even if the employer effectively communicates his side of the communication, but the employee is not paying his full attention to what his boss is saying, he wouldn't be able to make much of a difference.
<h3>3) Feedback</h3>
After sending and receiving communication, feedback should be given to complete the communication effectively. For example the employer may tell his boss about what he understood from his boss's speech, or what will he do to improve his performance.
