The speed of sound in air is 320 ms-1 and in water it is 1600 ms-1. It takes 2.5 s for sound to reach a certain distance from th
Nonamiya [84]

Answer:

Distance covered by the sound in air is 800 meter and the time taken by the sound in water for the same distance is 0.5 seconds.

Explanation:

Given:

Speed of sound in air = 320 m/s

Speed of sound in water = 1600 m/s

Time taken to reach certain distance in air = 2.5 sec

a.

We have to find the distance traveled by sound in air.

Distance = Product of speed and time.

⇒ Distance = Speed\times time\ taken

⇒ Distance = 320\times 2.5

⇒ Distance = 800 meters.

b.

Now we have to find how much time the sound will take to travel in water.

⇒ Time = Ratio of distance and speed

⇒ Time =\frac{distance}{speed}

⇒ Time =\frac{800}{1600}   <em>   ...distance = 800 m and speed = 1600 m/s</em>

⇒ Time =\frac{1}{2}

⇒ Time =0.5 seconds.

Distance covered by the sound in air is 800 meter and the time taken by the sound in water for the same distance is 0.5 seconds.

How can we help people with anger problems!?​
zubka84 [21]

If someone with anger issues is struggling to control their temper, great tips are:

1. Find something in your life that you've been through that may relate to what this person is angry about, and calmly share your story. For example, Tom is abnormally angry about not getting his new tool kit delivered on time. So you say, "I understand, one time I waited weeks for my phone case to come in and it upset me very much."

2. Take the angered individual to an isolated and private area. This gives them less triggers and is safer for others.

3. Teach the person coping skills when they are NOT currently having an episode. For example, Chloe is in a good mood while she is painting her nails. So you say, "Can I show you a coping skill for anger I found online? Its awesome! Just tense up every muscle in your body as hard as you can for 5 seconds, then release the tension slowly for 10 seconds. Repeat until you feel cooled down. Try it!"

4. If someone's anger problems become a threat to themselves or those around them, take this person to see a professional. It could be serious!
