F=1/T
therefore T=1/F
so thats T=1/20x10^6
T=5x10^-8seconds
D. I hope my answer helps you!
Answer: the drink cooled down to the same temperature as the room it was in.
Explanation: due to the change and temperature of the room, it cause the heat particles to exchange, causing it cool
The Continental crust is also less dense than oceanic crust, though it is considerably thicker; mostly 35 to 40 km versus the average oceanic thickness of around 7-10 km. About 40% of the Earth's surface is now underlain by continental crust.
Explanation:
Given:
v₀ = 0 m/s
v = 49 m/s
a = 9.8 m/s²
Find: t
v = at + v₀
49 m/s = (9.8 m/s²) t + 0 m/s
t = 5 s
