I am told that when determining the number of significant figures, if the decimal place is absent, then you start counting from the first nonzero number on the right side and continue counting to the left until you reach the last digit. However, if the decimal place is present, start counting the first nonzero number from the left and continue counting to the right until the final digit has been reached. For example, the number 50 only has two significant figures, while the number 50.00 has four significant figures. However, how does the number 50 have two significant figures? If I have to start countingfrom the right because of the absence of a decimal place, and I have to begin with the first non zero number, I would have to start from 5 and there is nowhere to count further to the left. How does the number 50 have two significant figures?
1. All answers to be entered via short answer are in the numerical format and presented up to the 3rd decimal place. Add trailing zeros if necessary, to complete your answer. NO NEED TO INCLUDE THE UNIT. For uniformity of answers, please be guided by the following examples: If your answer is 5.627594, enter 5.628 If your answer is 3.129934, enter 3.130 If your answer is 8.38, enter 8.380 If your answer is 1.2, enter 1.200 If your answer is 25, enter 25.000 If your answer is less than the value of 1, always place a zero before the decimal point (example: 0.5, enter 0.500) 2. In cases for answers in the exponential format, please be guided by the following examples and format: Do not convert your answer to decimal format If your answer from the calculator is 1.23454566 x 10E-4, enter 1.235x10^-4 (no spaces in between) If your answer from the calculator is 7.379566 x 10E-5, enter 7.38x10^-5 (no spaces in between) 3. For the atomic weights, it should be rounded to the nearest whole…

1. The inhabitants of a hypothetical exoplanet use a temperature system, called Pobius scale. The following equations relate their Pobius scale to our Fahrenheit scale. P = 2.5 F – 50 P + 50 F = %3D 2.5 Do the following conversions. 30°C = op a. 30°C to the Pobius temperature. Hint: First convert C to F, and then F to P -1050 °P = %3D b. -1050°P to Kelvin temperature. Hint: P to F; then F to C; then C to K
Instructions for this problem say, "Solve each problem and report your answer to correct significant figure and units. Remember that units multiply, divide, add, subtract, and simplify just like variables." (3.1 x 10^4 nm^2)^1/2 How do I solve with a half exponent? Image of my attempt attached.
Section 2-6 Carry out the following multiplications and divisions, expressing your answer in scientific notation to the correct number of significant figures. • NOTE: Enter numbers only; DO NOT SPELL the numbers. • Use a hyphen "-" for a negative sign. • DO NOT use a "+" symbol! . a) (3.200 × 107) × (1.10 × 10−²) × (2.3 × 10−7) b) 6.0x10-5 3.0x10³ X 10^ X 10^
