A special standard weight, known to weight 10 N to high accuracy, is used to check the accuracy of two spring scales. On the fir

zysi [14]

Answer:

16 % and 9 %

Explanation:

Accurate reading = 10 N

reading of first balance = 8.4 N

reading of second balance = 9.1 N

Percentage difference in first reading

= $\frac{True reading - reading of first balance}{True reading}\times 100 %$

= $\frac{10-8.4}{10}\times 100 %$ = 16 %

Percentage difference in second reading

= $\frac{True reading - reading of second balance}{True reading}\times 100 %$

= $\frac{10-9.1}{10}\times 100 %$ = 9 %

Plane a travels at 900km/h and plane b travels at 250/5.which plane travels faster

vesna_86 [32]

Explanation:

We have,

Speed of plane a is 900 km/h

Plane b is moving at a rate of $\dfrac{250\ km}{5\ h}=50\ km/h$

It is required to find which plane is faster. To find which plane is faster, we need to compare their speeds.

Speed of a plane a is 900 km/h and that of plane b is 50 km/h. So, we can say that plane a is moving faster.
