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.
Answer:
The speed of 250 g ball after collision is 14 m/s.
Explanation:
mass of first ball, m = 550 g = 0.55 kg
initial velocity of first ball, u = 8 m/s
mass of second ball, m' = 250 g = 0.25 kg
initial velocity of second ball, u' = - 8 m/s
Let the speed of the balls is v and v' after the collision.
Use conservation of momentum
m u + m' u' = m v + m' v'
0.55 x 8 - 0.25 x 8 = 0.55 v + 0.25 v'
0.55 v + 0.25 v' = 2.4 ..... (1)
Use the formula of coefficient of restitution,
For elastic collision, e = 1

By solving (1) and (2)
v = - 2 m/s and v' = 14 m/s
Answer:
Being silent most of the time is a good virtue under certain circumstances and environment. It is always advisable to remain quite silent and not be too quick to respond to situations or issues so as to avoid making and saying wrong words.
The ethics in a workplace involves communicating with others with less amount of talking as possible and more of body languages and signs. This is because the workplace is meant to be a serene place.
It's been a while since I've studied this, but my answers would be:
13. 5730 years. The half-life of a substance is the amount of time it takes for half of it to decay, and, according to the graph, half of the substance remained at 5730 years.
14. 10740 years. According to the graph, only 25% of the carbon remained after 10740 years.
15. 15 atoms. According to the graph, only 12.5% of the carbon remained after 16110 years. 12.5% of 120 atoms is 15 atoms.
16. 1600 atoms. According to the graph, if a sample of carbon is 10740 years old, only 25% of it remains. To find the original amount, multiply the current amount by (100% / 25%), which equals 4. So, 4. 400 atoms * 4 = 1600 atoms is the original amount.
