(a)
Interpretation:
Whether a tiny ant can be seen by atomic force microscope but not by optical microscope or not should be determined.
Concept introduction:
Objects are categorized on the basis of size range they fall in. Macroscopic objects are those which lie in the size range that human eye can perceive and microscopic objects are those which need the use of specialized instruments like electron microscope or atomic force microscope.
Human eye can detect approximately up to the size of

- Why should nonscience majors study science?arrow_forwardUsing dimensional analysis show how you arrived at your answer. if the diameter of a sodium atom is 3.14 x 10^-8 cm, how many sodium atoms would fit along a straight line exactly one (1) inch long?arrow_forwardCalculate the edge length in m and the volume in L for a cubical box that will “exactly” contain 4.32x1023 atoms. Assume the diameter of the Argon atom is 3.4 Å (1.000 Å = 1.000x10-10 m). Assume the atoms touch each other so that the closest distance between atomic centers (nuclei) is 3.4 Å and the atoms fill the box with MANY layers of Argon atoms.Note: a cubical box needs only one measurement to be defined because each edge of a cube is exactly the same length, l,so that the volume of the box, V = l3.arrow_forward
- Foundation Of College Chemistry can you please give me the answer step by step How many significant figues should the answer in each of these calculations contain? (e) 119.1-3.44 (f) 94.5/1.2arrow_forwardHow many nL are there in (3.67x10^3) cLarrow_forward3. Chromium forms a body centered cubic crystal. If the length of an edge is 2.884 angstroms, calculate the density (g/cm) and the radius of a chromium atom in angstroms.arrow_forward
- The sodium D lines from a sodium lamp consist primarily of a doublet at 589.5 and 589.0 nm. Suppose we can obtain a grating with 500 lines/cm of any size we choose. How long (in cm) should the grating be required to separate the two sodium lines in the first order? Suppose the full length of the grating is illuminated. Respond with the correct number of significant figures in scientific notation (Use E notation and only 1 digit before decimal e.g. 2.5E5 for 2.5 x 105) Type your numeric answer and submit 2.96E3 Hint R= lambda/Deta lambda=nLM N=1 for the strongest signals X You are incorrectarrow_forwardChoose the selection which most accurately gives both the value of the angle numbered 1 and the value of the angle numbered 2 in the figure above. Choose the best possible (most specific) answer. Other answers will be graded wrong. For example, if an angle is somewhat greater than 109.5 degrees, an answer which says that it is somewhat less than 120 degrees, while somewhat correct, will be graded wrong. a) Angle 1 is very close to 180 degrees and angle 2 is very close to 90 degrees. b) Angle 1 is somewhat less than 109.5 degrees and angle 2 is somewhat less than 109.5 degrees. c) Angle 1 is somewhat less than 109.5 degrees and angle 2 is very close to 90 degrees. d) Angle 1 is somewhat less than 109.5 degrees and angle 2 is somewhat less than 120 degrees. e) Angle 1 is somewhat more than 109.5 degrees and angle 2 is somewhat less than 109.5 degrees.arrow_forwardIn science it is often useful to estimate if a measurement is "in the right ballpark" by comparing it to a value that you already know. Given that the number of stars in the Milky Way is 100–400 billion and it is likely that most of the stars have at least one planet, what is the best estimate of the number of planets in the Milky Way?arrow_forward
