Ответ:
0.42 m/s²
Explanation:
Given:
v₀ = 15 km/h = 4.17 m/s
v = 90 km/h = 25 m/s
t = 50 s
Find: a
v = at + v₀
(25 m/s) = a (50 s) + (4.17 m/s)
a = 0.42 m/s²
Ответ:
gas
Explanation:
Solids are compact together, liquida arent compact but are still close, and gases are free roaming and may be very far apart from eachother.
