pychu [463]

Answer:

def filter_only_certain_strings(data_list):

   new_list = []

   for data in data_list:

       # fix here. change >= to >  

       # because we want to return strings longer than 5 characters in length.

       if type(data) == str and len(data) > 5:

           new_list.append(data)

   return new_list

How Does A Shoe Box Solar Cooker Work?
Natalija [7]

Answer:

the sun gives off light while at the same time gives off heat. the shoe box cooker takes that heat and light and reflects it around the shoe box. then the heat settles down into whatever is in the shoe box. the heat after being reflected around the shoe box is magnified by the foil wrapped in the box thus allowing the food or drink to be heated. the foil is a conductor of heat because it is metal .

Explanation:

hope this helps!

If you measured a pressure difference of 50 mm of mercury across a pitot tube placed in a wind tunnel with 200 mm diameter, what
mart [117]

Answer:

V=33.66 m/s

Re=448.8\times 10^6

Re>4000, The flow is turbulent flow.

Explanation:

Given that

Pressure difference  = 50 mm of Hg

We know that density of Hg=136000Kg/m^3

ΔP= 13.6 x 1000 x 0.05 Pa

ΔP=680 Pa

Diameter of tunnel = 200 mm

Property of air at 25°C

ρ=1.2Kg/m^3

Dynamic viscosity

\mu =1.8\times 10^{-8}\ Pa.s

Velocity of fluid given as

V=\sqrt{\dfrac{2\Delta P}{\rho_{air}}}

V=\sqrt{\dfrac{2\times 680}{1.2}}

V=33.66 m/s

Reynolds number

Re=\dfrac{\rho _{air}Vd}{\mu }

Re=\dfrac{1.2\times 33.66\times 0.2}{1.8\times 10^{-8}}

Re=448.8\times 10^6

Re>4000,So the flow is turbulent flow.
