At the lowest point on the Ferris wheel, there are two forces acting on the child: their weight of 430 N, and an upward centripetal/normal force with magnitude n; then the net force on the child is
∑ F = ma
n - 430 N = (430 N)/g • a
where m is the child's mass and a is their centripetal acceleration. The child has a linear speed of 3.5 m/s at any point along the path of the wheel whose radius is 17 m, so the centripetal acceleration is
a = (3.5 m/s)² / (17 m) ≈ 0.72 m/s²
and so
n = 430 N + (430 N)/g (0.72 m/s²) ≈ 460 N
Answer:15th
Explanation:
I believe it will fall on the 15th stair because 10 times 15 is 150 divided by 10 m/s equals 15
Answer : Time taken for the light to reach earth is 
Explanation :
Given that,
Speed of Ultraviolet light, 
Distance covered by the light, 
We have to find the time taken (t) by the light to reach on the surface of earth.
t = 133333333.333 seconds
or
Hence, this is the required solution.
Oxygen, hydrogen, sodium, chlorine, lead, iron. Hope this helps!!!
