zhannawk [14.2K]

Answer:

The correct answer to the following question will be "The wavelengths of the electron beams are also much shorter or less than illumination and visible light".

Explanation:

TEM seems to be a methodology of microscopy during which a pulse of electrons is transferred to create the effect through some kind of microscope, could approach biological objects at the sub-nanometer standard, as related to hundreds of nano-meters for either the absolute best microscope with super-resolution.

Also because of the electron beam's distances, they are still much shorter or smaller than daylight and infrared light, meaning that biological objects and artifacts can be resolved.

Research the disadvantages of the computer and explain them.​
lisabon 2012 [21]

Answer:

Too much sitting-affects the back and makes our muscles tight

Carpal tunnel and eye strain-moving your hand from your keyboard to a mouse and typing are all repetitive and can cause injuries

Short attention span and too much multitasking-As you use a computer and the Internet and get immediate answers to your questions and requests, you become accustomed to getting that quick dopamine fix. You can become easily frustrated when something doesn't work or is not answered in a timely matter.

Suppose for the worst case, given input size n: Algorithm 1 performs f(n) = n2 + n/2 steps Algorithm 2 performs f(n) = 12n + 500
melomori [17]

Answer:

29

Explanation:

for n=28:

--------------

Algorithm 1 performs f(n) = n2 + n/2 = 28*28 + 28/2 = 798

Algorithm 2 performs f(n) = 12*28 + 500 = 836

for n=29

--------------

Algorithm 1 performs f(n) = n2 + n/2 = 29*29 + 29/2 = 855.5

Algorithm 2 performs f(n) = 12*29 + 500 = 848

so, for n=29, algorithm 2 will be faster than algorithm 1
