Eric notices that his flashlight does not turn on when he flips the switch. what is the least appropriate hypothesis for eric to make? the flashlight does not want to work. the batteries need to be replaced. the light bulb is burned out. the wiring has frayed.

The flashlight does not want to work.

Explanation:

The flash light does not turn on when Eric flips the switch. There could be many reasons for flashlight not to work. The batteries might have drained out and need to be replaced. The light bulb is is burned out or the wiring has frayed. The least appropriate hypothesis for Eric to make is that flashlight does not want to work. This is cannot be a scientific reason.

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
