After performing some calculations, your calculator gives you the following results. How will you round them before presenting them in your report? Make a comment if something does not seem right. (3 points each) a) 401.6473 ± 7.0912 ms b) 57.212 ± 1.612 kg c) 8.12754×107 ± 2.847×105 m d) 2.94 ± 8.803 µN e) 294 ± 0.00481 cm

⇒ 401.6 ± 7.1 ms

⇒ 57.2 ± 1.6 kg

⇒ 8.1 × 107 ± 2.9 × 105 m

⇒ 2.1 ± 8.8 µN

⇒ 294 ± 0.005 cm

Explanation:

As given all equation we do without calculation we will  get here round these calculations which is given below as  

a) 401.6473 ± 7.0912 ms

⇒ 401.6 ± 7.1 ms

b) 57.212 ± 1.612 kg

⇒ 57.2 ± 1.6 kg

c) 8.12754×107 ± 2.847×105 m

⇒ 8.1 × 107 ± 2.9 × 105 m

d) 2.94 ± 8.803 µN

⇒ 2.1 ± 8.8 µN

e) 294 ± 0.00481 cm

⇒ 294 ± 0.005 cm

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
