Airida [17]

Answer:

a) 2.22 %

b) Range would be 60±1.998 km/h

Explanation:

Percentage uncertainty indicates the error of a reading. With the percentage uncertainty error for a measurement can be calculated.

a) Percentage uncertainty would be

$2\times \frac{100}{90}=2.22%$

Percent uncertainty is 2.22%

b) For 60 km/h error would be

$\frac{2.22}{100}\times 90=1.998$

Range would be 60±1.998 km/h

1 pa = 1 N/m^2

you have 300 000 of these = 300 000 N /m^2

but only an area of .2 m^2

300 000 N / m^2 * .2 m^2 = 60 000 N
