Answer:
the percent increase in the velocity of air is 25.65%
Explanation:
Hello!
The first thing we must consider to solve this problem is the continuity equation that states that the amount of mass flow that enters a system is the same as what should come out.
m1=m2
Now remember that mass flow is given by the product of density, cross-sectional area and velocity
(α1)(V1)(A1)=(α2)(V2)(A2)
where
α=density
V=velocity
A=area
Now we can assume that the input and output areas are equal
(α1)(V1)=(α2)(V2)
Now we can use the equation that defines the percentage of increase, in this case for speed
Now we use the equation obtained in the previous step, and replace values
the percent increase in the velocity of air is 25.65%
hope it help

Answer:
option C is the answer
Explanation:
From the question we are told that the bundle (10,10 ) gives the utility that is = 4
And also for Leonid more is better(i.e more bundle of food and transportation consumed the more his utility ) then we can infer that the utility for the bundle (20,20) would be greater than 4
And looking at the option the only value greater than 4 is 1000 hence option c is the answer
