Answer:
The thickness of the layer increases as the flow progresses along the surface and the flow nature changes from laminar to turbulent until finally the fluid separates from the body.
Explanation:
The thickness of the boundary layer depends on it's distance from the leading edge of the body with thickness increasing along the flow. This can be attributed to the viscosity of the fluid that acts as a messenger that propagates the disturbance from the surface until the thickness where the velocity of fluid approaches the flow velocity of free stream.
Also the nature of the flow changes from laminar to turbulent which is attributed to the variation in the leading edge distance.
The answer is C because the word graphic means picture.
Answer:
a) 4.7 kΩ, +/- 5%
b) 2.0 MΩ, +/- 20%
Explanation:
a) If the resistor has the following combination of color bands:
1) Yellow = 1st digit = 4
2) Violet = 2nd digit = 7
3) Red = multiplier = 10e2
4) Gold = tolerance = +/- 5%
this means that the resistor has 4700 Ω (or 4.7 kΩ), with 5% tolerance.
b) Repeating the process for the following combination of color bands:
1) Red = 1st digit = 2
2) Black = 2nd digit = 0
3) Green = multiplier = 10e5
4) Nothing = tolerance = +/- 20%
This combination represents to a resistor of 2*10⁶ Ω (or 2.0 MΩ), with +/- 20% tolerance.
