6 a bulb thermometer gives an indoor temperature reading of 21 degrees celsius. a digital thermometer in the same room gives a reading of 20.7 degrees celsius. which devise is more precise? explain.

The answers are below

Explanation:

1.-  Change 9.0 x 10^7 from scientific to standard notation

Just move the decimal point 7 places to the right

                 90000000

2 Change 3.2 x 10^-5 from scientific to standard notation

Just move the decimal point 5 places to the left

              0.000032

3 Which types of measurements are appropriate for scientific notation? *

The speed of light                  is appropriate

The speed of a snail               isn't appropriate

The speed of your car            isn't appropriate

4 Write 0.0000000000372 grams in scientific notation. Then convert to SI base units.

Just move the decimal point 11 places to the right

                       3.72 x 10 ⁻¹¹ grams     =  3.72 x 10 ⁻¹⁴ kg

5 Write 45,000,000,000 kilometers in scientific notation. Then convert your answer to SI base units

Just move the decimal point 10 places to the left

             4.5 x 10 ¹⁰ km = 4.5 x 10¹³ m

6 A bulb thermometer gives an indoor temperature reading of 21 degrees Celsius. A digital thermometer in the same room gives a reading of 20.7 degrees Celsius. Which devise is more precise? Explain.

I think the digital thermometer is more precise because it can measure decimals, then the reading is closer to the right temperature. The other thermometer can't read decimals.

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

thats a little if u want the answer just look it up on google thats what i do haha : )
