Answer:
27.35m
Explanation:
For the calculation of the Support Force we rely on the formula for obtaining the force in a cylinder of a certain length l,
Here each term is,
= Lift force
= density of air
= vortex strength
For this last equation, its mathematical representation is given by,
Here each term is,
a= 1m, radios of cylinder
, the velocity of cylinder surface.
In order to find the density of the area at 2000m we will refer to the table of Standard Atmosphere of the United States, that is 
Replacing the values,
Clearing l and solving for it we have,
<em>In this way we can conclude that the length of the cylinder must be 27.35m</em>
Answer:
A kilowatt (kW) is a unit of power.
Explanation:
The power of an object is given by :
Here,
E is the energy required
t is time
The SI unit of power is Watts and the SI unit of energy is Joule. the commercial unit of energy is kilowatt per hour.
Option (1) : A kilojoule (kJ) is a unit of power is incorrect.
Option (2) : A gigawatt (GW) is a unit of energy is incorrect.
Option (3) : A watt (W) is a unit of energy is incorrect.
Option (4) : A kilowatt x hour per year (kWh/yr) is a unit of energy is incorrect.
Option (4) : A kilowatt (kW) is a unit of power is correct.
Hence, the correct option is (d).
The appropriate answer is c. silty clay loam. This is the most likely soil that was present in the garden before sand was added to balance it. This type of soil contains an even mix of silt and clay. This type of soil does not drain well and tends to hold water. This would not be suitable for most garden variety plants. Adding sand to the soil ensures better drainage and removes moisture that would rot roots or create conditions for fungi to develop.
