Answer:
The pressure difference of the first bubble is
The pressure difference of the second bubble is
The pressure difference on the second bubble is higher than that of the first bubble so when the valve is opened pressure from second bubble will cause air to flow toward the first bubble making is bigger
Explanation:
From the question we are told that
The radius of the first bubble is
The radius of the second bubble is
The surface tension of the soap solution is
Generally according to the Laplace's Law for a spherical membrane the pressure difference is mathematically represented as
Now the pressure difference for the first bubble is mathematically evaluated as
substituting values
Now the pressure difference for the second bubble is mathematically evaluated as
I think the answer is (C.) but im not sure
Answer:
spring constant of the spring will be equal to 317.33 N/m
Explanation:
We have given mass of the child m = 6.80 kg
Spring is stretched by length of 0.210 m . so x = 0.210 m
Acceleration due to gravity
Force on the child will be equal to
This force will be balanced by spring force
And spring force is equal to F = Kx
So kx = mg
k = 317.33 N /m
So spring constant of the spring will be equal to 317.33 N/m
