What is the average size of a cell?
Figure 1 Biological variations in cell size.
Eukaryotic cells average 10–20 μm in diameter, but the range to which cells grow is diverse.
The cells in this figure are drawn close to scale to emphasize the size variations..
Is your image exactly the same in size as you are?
The image distance always equals the object distance. The size of the image is the same as the object (the mirror does not magnify the image).
How do you tell a person’s height from a photo?
If there is something of a known height in the background or foreground, you can triangulate the height of the person using trigonometry. If you know the scale of the photo ( 1/10 or 1./20 for example) that it is possible to measure height in the photo and multiply b scale factor to get the real height of the person.
What has the highest magnification?
pentaceneThe highest magnification image ever created shows a single molecule of pentacene. Pentacene is a hydrocarbon which consists of five linearly fused benzene rings and has a molar mass of 278 g. mol-1.
How do you calculate the actual size of a specimen?
Calculation of Actual Size: To calculate the actual size of a magnified specimen, the equation is simply rearranged: Actual Size = Image size (with ruler) ÷ Magnification.
How do you calculate actual magnification and drawing size?
a. The drawing is roughly 7 cm long. This equates to 70 mm or 70,000µm.b. The actual size of the organism is about 500 µm.c. Drawing magnification = drawing size / actual size.70,000 µm / 500 µm = 140 X.Drawing Magnification = 140 X.
What is the formula for calculating magnification?
Magnification = scale bar image divided by actual scale bar length (written on the scale bar).
How do you calculate field diameter?
Calculating Field of View For example, if the eyepiece reads 10x/18, and the magnification of your objective lens is 40, multiply 10 and 40 to get 400. Then divide 18 by 400 to get an FOV diameter of 0.045 millimeters.
How big is a jail cell?
In the United States old prison cells are usually about 6 by 8 feet in dimension which is 48 square feet (moreover however American Correctional Association standards call for a minimum of 70 square feet = 6,5 m2), with steel or brick walls and one solid or barred door that locks from the outside.
Why cells are so small?
Cells remain small because all materials that are exchanged between the cell and its environment, like oxygen and glucose, must pass through the cell membrane. If materials cannot be exchanged efficiently, then the cell could die. In this activity, you will explore how surface area and volume limit the size of cells.
How big is the biggest cell?
about 15cm to 18 cm long and wideThe largest cell is an ostrich egg, it is about 15cm to 18 cm long and wide.
How do I find the actual size of an image?
Control+click on an image to see an image’s properties.Click Finder on your Dock.Find the image you want to check.Control+click (ctrl+click) your image. A menu appears.Click Get Info. … Expand the General: section to see your image’s file size.Expand the More Info: section to see your image’s dimensions.
What is the size of 50 KB photo?
Dimensions 200 x 230 pixels (preferred) Size of file should be between 20kb–50 kb. Ensure that the size of the scanned image is not more than 50KB. If the size of the file is more than 50 KB, then adjust the settings of the scanner such as the DPI resolution, no.
