Answer:
2.25×10¯³ mm.
Explanation:
From the question given above, we obtained the following information:
Diameter in micrometer = 2.25 μm
Diameter in millimetre (mm) =?
Next we shall convert 2.25 μm to metre (m). This can be obtained as follow:
1 μm = 1×10¯⁶ m
Therefore,
2.25 μm = 2.25 μm / 1 μm × 1×10¯⁶ m
2.25 μm = 2.25×10¯⁶ m
Finally, we shall convert 2.25×10¯⁶ m to millimetre (mm) as follow:
1 m = 1000 mm
Therefore,
2.25×10¯⁶ m = 2.25×10¯⁶ m /1 m × 1000 mm
2.25×10¯⁶ m = 2.25×10¯³ mm
Therefore, 2.25 μm is equivalent to 2.25×10¯³ mm.

Answer:
273.9 fathom
Explanation:
Fathom (ftm) and rod are the units of length used in the imperial and the U.S. customary systems.
Fathom is an unit used for the measurement of depth of water. It is equal to 1.8288 m.
Rod, also known as perch or pole, is equal to 5.0292 m.
∵ 1 fathom = 0.364 rod
and 1 rod = 2.75 fathom
∴ 99.6 rod = 99.6 × 2.75 fathom = 273.9 fathom
<u>Therefore, maximum depth of Lake Tahoe = 99.6 rod = 273.9 fathom</u>
