Ascientist conducted one trial of an experiment and got unexpected results. how can the scientist increase confidence in the results? by repeating the experiment several times by changing the experimental procedure by asking other scientists what they think about the results by modifying the results so they are close to the expected results

by repeating the experiment several times  

Explanation:  

A scientist conducted one trial of an experiment and got unexpected results. Therefore, he should repeat his experiment and see if he is getting the same result again or not. If the result is again the same and does not matches his expectations then he should discuss the results with other scientist. If the result is different, then he should check for the cause of error.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
