Answer:
Drop each ball from the platform three more times
Explanation:
Reliability or precision means how much the measured values vary from each other when measured by performing the same experiment repeatedly.
When measuring values by observation in physical experiments of this nature, it is best to perform the experiment and measure the values at least three times. The more the better.
In such measurements there is always a margin of error, e.g how at exact time you start and stop the stop-watch. There may also be a but harder or softer side of ball (tennis ball strip) touching the ground. In order to minimize such and some other margin of errors, it is advisable to measure the values more than 3-4 times, and then take their mean. The value now obtained would be would reliable or precise.
Second and third options are incorrect because they will have no effect on improving the reliability.
In order for the fourth option to be correct, the other people need to do the same (not similar) experiment, with the same balls and same conditions/instruments. That would be equivalent to repeating the experiment 3-4 times, which is already covered by first option.

In this excerpt, Jim's character is developed indirectly, through his lack of action.
<h3>What is Characterization?</h3>

Explanation:
That is the exact facial expression I had when I was a child. I know how it feels. That sadness, sorrow, misery and pain. As the child walked towards the garbage bin, I quietly followed his steps. The smell was unbearably foul. What is he possibly doing? Scavenging for metal tins? Or maybe plastic bottles? The next thing happened was an 'I can't believe my eyes'. That boy with patched clothes was eating the food waste right from the garbage.
I once had a tough life. Lucky for me, I was adopted by a rich family. This boy faced much more trouble than I did. I went after the child after seeing him searching from bins to bins. 'Care for some buns?,' I asked. WOAH! He turned in shock, not expecting strangers. At first the boy was confused and refused to accept my kindness, but eventually after persuading him for a few times, he took it and walked away.
Feeling unsatisfied and curious, I pursue on tracking his path. With confusion, I wonder what was he still doing by the bins. After a few questions and answers, I found out that he was an orphan and his mom is disabled.They live in a small wooden house that was waiting for it's time to collapse. He was the only hope to support his siblings of 5. His story was heartbreaking that I tears slowly rolled down my cheeks. The only thing on my mind was this kid needs help!
Luckily I have a friend who work at the public welfare center. The boy's family was supported by the government and was moved to a new house at a rural area. They begin a fresh new life there. He and his siblings was given an education. The boy did a part-time work in order to support the family finances. I could see his face becoming radiant day by day.
I would visit them twice a month to check if they are comfortable with the new life. Turns up there is nothing to be worried about as result was positive. His family was starting to adapt to the new surrounding. His determination and 'never giving up' actions had helped his family survived. Before I left after my last visit, he thanked me. I could barely heard him saying 'Well, with everything that happened, I hope that I will never face sadness again'.
