A new physics unit of distance is created and called the Zarkov. A student informs you 1 Zarkov (1 Za) is exactly equivalent to 8 inches. Convert 4.44 × 10% min² to h. If hard Zaš to read: asking you to convert minutes squared over Zarkov's cubed to hrs squared over meters cubed. Answer in E notation without units in the box. I am assuming your output units are m3 Note: for some numbers the computer will convert your E notion to another notation without the E.that will not cost you points. To be clear regarding E notation, I will provide an example of what l'm talking about: 1.23 x 104 = 1.23e4
What can you say about the accuracy of your measurements? What can you say about the precision of your measurements? (Measure the longest dimension of the room twice, using two different techniques. Do the measurement in feet and inches. Then convert to meters.) Below is what I got. Tape Measure - 146 inches > 3.7084 meters / 12 feet and 2 inches = 12.1667 feet > 3.70840 meters Ruler - 144.5 inches (144 + 1/2) = 3.6703 meters / 12.0416 feet = 3.67027 meters

When you perform the following operations, how many significant figures should your answer have? Assume these are measured quantities.(4.0005 x 105) + (8.000 x 102) =Hint: exponents in scientific notation must match. For example, as a tutorial, (1.11 x 10-3) + (2.000 x 10-2) must be changed to (0.111 x 10-2) + (2.000 x 10-2) to make exponents match.1.11 x 10 -3 = 0.111 x 10 -2The numbers in this tutorial are not the same numbers as in your problem.When adding and subtracting, there should be no more places past the decimal as in the measured number with the fewest.
Now consider the expression 4.0×10^3 + 4×10^2. Determine the values of a and k when the value of this expression is written in scientific notation.
Convert each measurement to basic SI units without using power-of-ten prefixes or power-of-10 exponents. Show your work beside your answer, or on a separate sheet of paper.
