Answer: 12.12 m
Explanation:
We have the following data:
is the speed of the water wave
is the frequency of the water wave
Now, the speed of a wave is given by the following equation:
Where is the wavelength.
Isolating :
Finally:
This is the water wave wavelength
Answer:
k=188.46 N/m
Explanation:
Given that
m= 30 gm
Additional mass = ΔM
Lets take spring coefficient = k
at the equilibrium position
F= k Δl =( m + ΔM)g
Δl = change in the spring length
k Δl = ( m + ΔM)g
Δl = m g /k + g/k ΔM ---------------1
We know that equation of line given as
y = c + S x -----------------2
By compare equation 2 and 1
slope = s
S= g/k
Given that slope S= 0.052 m/kg
S =g/ k= 0.052
g=9.8 m/s²
9.8 = 0.052 k
k=188.46 N/m
So the spring constant is 188.46 N/m
Assuming you are asking about some sort of oscillation, the magnitude of the net force is maximum where the acceleration of the object is the largest. The velocity of an object is maximum where the acceleration is zero.
