A student performs the experiment and measures the distance between photogates: d = 50 ± 0.1 cm, the times measured by photogates: t0 = 0.052 ± 0.001 s and t1 = 0.035 ± 0.001 s, and the cart’s length: s = 10 ± 0.05 cm. Find the acceleration a of the cart and estimate the uncertainty in a.

the results is a decrease in air temperature with an increase of altitude.

explanation:

uranium fissions/breaks up giving out energy and neutrons

it is called kinetic energy

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
