Answer:
The difference between the length of the sides of the fish tank is guy Harvey's restaurant and a fish tank in gift shop is 2 feet.
Explanation:
The cube shaped fish tank in guy Harvey's restaurant has volume 64 cubic feet.
Volume of the cubic tank is given by,
V = 
64 = 
l = ![\sqrt[3]{64}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D)
l = 4 feet
The cube shaped fish tank in the gift shop is 8 cubic feet
Volume of the cubic tank is given by,
v = 
8 = 
8 = ![\sqrt[3]{8}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D)
a = 2 feet
The difference between the length of the sides is given by,
d = l - a
d = 4 - 2
d = 2 feet
The difference between the length of the sides of the fish tank is guy Harvey's restaurant and a fish tank in gift shop is 2 feet.
Answer:
R_2 = 7.647 m
Explanation:
HI!
Let us consider that the aballon is filled with a gas that follows the ideal gas equation. Since the amount (number of moles) of the gas is constant we should have:

Therefore, we can have the following relationship between two differnet states given their Volume, Pressure and Tempreature:

Since the volume of a sphere is

The relathionship will be:

Solving for R_2:
![R_2 = R_1 \sqrt[3]{\frac{P_1 T_2}{P_2 T_1}}](https://tex.z-dn.net/?f=R_2%20%3D%20R_1%20%5Csqrt%5B3%5D%7B%5Cfrac%7BP_1%20T_2%7D%7BP_2%20T_1%7D%7D)
Where the index 2 is the state at the lift-off and the index 1 denotes the state at its maximum radius. Replacing all the values given we find that:
R_2 = 7.647 m
