Answer:
Its not really possible I don't think. UNLESS! You fall into a manhole then find a wirling vortex in the sewers! : )
Explanation:
Answer:
the answer is UV Radiation
Answer:
0.15
Explanation:
Assuming the rope is horizontal, sum the forces in the y direction:
∑F = ma
N − mg = 0
N = mg
Sum the forces in the x direction:
∑F = ma
F − Nμ = ma
Substitute:
F − mgμ = ma
mgμ = F − ma
μ = (F − ma) / (mg)
Plug in values:
μ = (8.0 N − 2.0 kg × 2.5 m/s²) / (2.0 kg × 9.8 m/s²)
μ = 0.15
I think it's 'C' but I won't know for sure until you let me see the diagram.
You should calculate 40 kg and the radius 3mm.
