Answer:
22km/h
Explanation:
The speed of the keys relative to the ground will be given by the sum of speed of keys with respect to the ground and the speed of keys with respect to the skater
Given that the speed of keys with respect to the ground is 8 m/s while the speed of keys with respect to skater is 14 km/h then the relative speed which combines both speeds will be 8+14=22 km/hr
Answer:
Carbon 12
Explanation:
I don't 100% know what to put here, but...
When you remove the nucleus from an oxygen atom, almost everything of the base oxygen is essentially stripped away. Since almost everything is made of carbon, and Carbon 12 is one of the most common forms of Carbon, Carbon 12 would be what is left.
Answer:
25 m
Explanation:
Given:
v₀ = 10 m/s
v = 0 m/s
a = -2 m/s²
Find: Δx
v² = v₀² + 2aΔx
(0 m/s)² = (10 m/s)² + 2 (-2 m/s²) Δx
Δx = 25 m
