Physics
Its incorrect. and you shut up so calles i am awesome

Physics
t₁=250/9 – 250/7 = 63.5 s t₂ = 500/8 = 62.5 s Δt=t₁-t₂=63.5 – 62.5 =1 s.

physics
mgh= mv²/2 v=sqrt(2gh)

physics
Work/time = Power = Force x speed The force is exerted on the bicycle to maintain the constant speed is F=P/v=400/10 = 40 N

physics
v=const => net force =0

physics
centripetal acceleration a= v²/R= = 4/0.5=8 m/s² centripetal force F= mv²/R= =0.05•4/0.5=0.4 m/s²

physics
centripetal acceleration a= mv²/R= =0.05•4/0.5=0.4 m/s²

Physics
Pb = lead

physics
Please can you tell the numerical value

physics
Tsinθ = mv²/R Tcosθ = mg tanθ=v²/Rg
