L=ℏ √l(l+1) =√l(l+1)• h/2π l= n-1 => l=0, 1, 2, 3,4. L(max) = √(4•5) • 6.63•10⁻³⁴/2π=4.72•10⁻³⁴ kg•m²/s L(min)= 0
Physics Need help plz
The uncertainty in speed Δv = 0.22 m/s Δp•Δx =h/4π Δmv•Δx =h/4π Δv•Δx =h/4πm Δx= h/4π•m •Δv= =6.626•10⁻³⁴/4π•1900•0.22=1.26•10⁻³⁷...

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

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

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
