While on vacation at the beach, Sarah noticed that during the day the sand was really hot, the ocean cool, and a breeze flowed constantly from the ocean towards her hotel. She also noticed that during the night, the ocean felt warmer than the sand and the breeze was reversed, blowing out to sea. Explain the following to Sarah:

1. Why was the sand so much warmer during the day and cooler in the evening

2. Why did the breeze blow towards the hotel during the day

3. Why did the breeze blow out to sea at night

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

answer///terminator or twilight zone;

total distance/total time

(85 + 82)/(5+3)
