What is the maximum magnification of a SEM?
A scanning electron microscope has a very large depth of field which makes the images produced appear three dimensional. Magnifications from 25X to 250,000X (250 times the magnification limit of a light microscope) are possible. Although my Science Text book says it can reach a magnification of 300 000X, but most specimens are easier to view at magnification less than 10 000X.
3.2 percent of 68 000?
68 000x 0,032 = 2176
To view a specimen 1 000 000x what kind of microscope do you have to use?
Electron Microscope
Is the optical micrscope stronger than electron in any way?
No. An extremely powerful optical microscope can magnify up to 1 000x. While this is a considerable amount, electron microscopes routinely magnify up to 1 000 000x.Electron microscopes are also able to produce 3D images of the specimen, while optical microscopes can only accomplish this task rather poorly at lower magnifications (10x-100x)
What expression is equivalent to x to the negative fourth power?
the answer would be .000X because if the power is negative than the answer will be a decimal.
How many bit strings of length 8 begin with three 0s?

No further requirement is made about the state of the remaining 5 bits; the bit pattern in the byte thus is 000x xxxx (where 'x' can be either '0' or '1'). Five bits of 'x' allow for 25 = 32 combinations.
How do you play D on the ukulele?
One way on the standard G'CEA tuning, the D chord is created by barring the top three strings at the second fret. The tab would look like this: 0000 XXX0 0000 0000 Others find it easier to play by stopping all strings at the second fret (with index finger) then also stopping first string at the fifth fret with little finger. The tab would look like this: 0000 XXX0 (only higher stopping of first string is shown - later) 0000 0000 000X Several advantages to this second way. 1: Some people feel that it is easier. 2: The root note (D) is played twice (1st and 3rd string) and is also LAST note played on downward stroke - and first on upstroke. 3: If D7 is then required - second finger at third fret on first string - replaces little finger at fifth fret, which retains the root note which is still on third string. 4: Fretting all of the stings allows one to control the length of the notes using the 'squeeze' method of damping the strings by pulling the fingers off the fret board. One of the disadvantages of the second method is that it can make it more difficult to transition to some of the other chord fingerings commonly used. This can be mitigated to some extent by learning alternative methods for other chords. You'll find the one that works best for you and the music you are playing!
What is short-hand notation?
(a)1. Let x = the repeating decimal. (a) x = 0.151 515 151 5…2. Multiplyx by the power of 10 thatcontains the same number of zeros asthere are digits in the repeating pattern.The pattern contains 2 digits somultiply by 100.100x = 15.151 515 15…3. Subtractx from the new value. 100x - x = 15.151 515 15 - 0.151 515 1599x = 154. Solve the linear equation found, puttingyour answer in simplest (improper ifnecessary) fraction form.x==5.
