Figure 1: An image — an array or a matrix of pixels arranged in columns and rows.
In a (8-bit) greyscale image each picture element has an assigned intensity that
ranges from 0 to 255. A grey scale image is what people normally call a black and
white image, but the name emphasizes that such an image will also include many
shades of grey.
Figure 2: Each pixel has a value from 0 (black) to 255 (white). The possible range of the pixel
values depend on the colour depth of the image, here 8 bit = 256 tones or greyscales.
A normal greyscale image has 8 bit colour depth = 256 greyscales. A “true colour”
image has 24 bit colour depth = 8 x 8 x 8 bits = 256 x 256 x 256 colours = ~16
million colours.
<em><u>Answer</u></em>
5 hours
<em><u>Explanation</u></em>
The two working together can finish a job in
Also, working alone, one machine would take one hour longer than the other to complete the same job.
Let the slower machine working alone take x hours. Then the faster machine takes x-1 hours to complete the same task working alone.
Their combined rate in terms of x is
This should be equal to 20/9 hours.
Multiply through by;
Factor to get:
It is not feasible for the slower machine to complete the work alone in 4/9 hours if the two will finish in 20/9 hours.
Therefore the slower finish in 5 hours.
Answer:
The answer is "Right".
Explanation:
In computer science, editing is the primary activity, which is used by the users to handles graphics, tables, and other things. It can be divided into two types first is internal(default) and the second is manual.
- In the manual editing, to edit the column of the table we just right click on the column.
- It enables you to edit option, in which we edit column according to our desire.
To start combining, select the Merge Mode option on the Comparison tab. Next, click the button next to the line you wish to merge in order to replace content from the right pane with content from the left pane.
<h3>How is boundary layer thickness calculated?</h3>
- Where x is a position parallel to the wall, y is a coordinate normal to the wall, v is a (small) viscosity, u = (u, v) is the velocity, is the vorticity, and so on. The boundary conditions are as follows: u(x,y = +,t) = U, and u(x,y = 0,t) = 0.
- To gauge the overall pressure, a vertically sliding Pitot tube is employed. So that the growth of the boundary layer in the flow direction can be seen, the total pressures can be recorded at various distances from the plate surface. Static pressure is gauged at a different measurement location.
- To start combining, select the Merge Mode option on the Comparison tab. Next, click the button next to the line you wish to merge in order to replace content from the right pane with content from the left pane. Alternatively, you can pick a discrepancy and choose Replace Content from the Comparison tab.
