D -
You basically keep varying the coefficient so until the number of atoms for each element is equal. I started with iron to show how you might have to change coefficients but it would be more efficient and quicker to start with oxygen since it changes the value or iron required.
I believe the answer is <span> D. Thinking about what they're saying
Interrupting them will make them unable to finish their full message/thought to you. Looking away while they're speaking will make you reduce your attention and unable to process the information properly. Thinking about how you'll response also limit your attention to them and could make you cloud your opinion and misinterpret what's they're saying.</span>
Answer:
Explanation:
Let the ball is thrown upwards with speed u and reaches upto height h.
Use III equation of motion
here, final velocity v = 0
So, 
Now as the ball reaches the maximum height, it starts falling freely. Let it strkes with the ground with velocity v'.
here, u = 0
So, 
It means the velocity is same as the velocity of projection.
<span>Answer: Doppler radar
Doppler radar or weather radar is used to locate precipitation,</span> forecast future intensity, calculate
or detecting its motion and estimates precipitation whether it is a rain, snow,
hail or storm. They are also helpful in determining the structure of storms and
its potential to cause severe weather.
Moreover, if a portion of the atmosphere becomes
saturated with water vapor, it will condense and precipitate allowing Doppler
radar to analyze and observe precipitation.
