The precision of a laboratory instrument is ± 0.05 g. the accepted value for your measurement is 7.92 g. which measurements are in the accepted range? check all that apply.

7.85 g

7.89 g

7.91 g

7.97 g

7.99 g

7.89g, 7.91g and 7.97 g

Explanation:

Precision has to do with the maximum value of allowance that can be accepted when added to the original measurement of an object.

Since the accepted value of measurement is 7.92g with precision of ± 0.05 g

The accepted range will be either 7.92+0.5 and 7.92 - 0.5 to give 7.97g and 7.87g

This two values are the maximum and minimum value that can be accepted respectively. Any value that falls in between can also be accepted.

7.87g<=x<=7.97 (acceptable range)

Therefore only 7.89g, 7.91g and 7.97g falls within this range.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
