Answer:
The diameter of the hose is 0.326 mm.
Explanation:
Given that,
Speed of car = 28 miles/galllon
We need to calculate the radius
The rate of flow of fluid is from the equation of continuity

Where, A = area of cross sectional

We know that,
The velocity is the ratio of displacement of gas per unit time.


Put the value into the formula



We need to calculate the diameter of the hose

Put the value of r


Hence, The diameter of the hose is 0.326 mm.

Answer:
The length of the string is 0.051 meters
Explanation:
It is given that,
Tension in the string, T = 240 N
Mass of the string, m = 0.086 kg
Speed of the wave, v = 12 m/s
The speed of the wave on the string is given by :

M is the mass per unit length of the string i.e. M = m/l.......(1)
So, 

M = 1.67 kg/m
The length of the string can be calculated using equation (1) :


l = 0.051 m
So, the length of the string is 0.051 meters. Hence, this is the required solution.
