Momentum is a property of moving objects but not stationary objects. You can see this in the formula because momentum equals mass times velocity squared (p=m*v^2). You would not have momentum if you didn't have velocity. Stationary objects have potential energy, and things with potential energy do not have velocity. This is why momentum is a property of moving objects but not of stationary objects.
Answer:
λ = 3.4 × 10^18m
Explanation:using Rydberg equation:
1/λ = RH •Z^2[ (1/n1) - (1/n2) ]
RH = Rydberg constant = 2.18x 10^-18j)
n1 and n2 = energy levels (n2 >n1)
Z = atomic number = 4
Substitute
1/λ = 2.18x 10^-18• [ (1/3) - (1/5) }
λ = 3.4 × 10^18m

Answer:
0.96 m, upward
Explanation:
Initial velocity, u=0
Where 
Substitute the values
Hence,the block moves upward because displacement is positive.
