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.
The fifth labor is hardesr
Answer:
Join.
Explanation:
The word "braid" is, originally, used to describe the act of lacing or weaving things together such as hair or yarn. It is the interlacing act that is typically known as a braid.
In the given sentence, the speaker uses this word to talk about how "immigrants braid their past into American story", implying how immigrants' stories are included in American stories. And the best word to replace or, the word that means the closest to "braid" is "join", as they both imply the 'inclusion, the fusion' of two elements.
Thus, the word "join" will best replace the word "braid" in the given sentence.
