IonlyneedpartD.Therestoftheinformationisonlyforreference Expressing numbers using powers of 10 (called scientific notation) has several advantages. First, you can easily tell how big a number is. If a number were written as 3180000031800000, you would have to count the digits to know its magnitude. However, 3.18×1073.18×107 is immediately seen to be somewhere in the neighborhood of 10 million (107107). In addition, the number of significant figures is just the number of digits in the factor preceding the exponent of 10. Since the number 3.18 has three significant figures, so does the entire number 3.18×1073.18×107. If you knew this number to five significant figures, then you would write 3.1800×1073.1800×107. Multiplying numbers in scientific notation When you multiply two numbers in scientific notation, you can multiply the two numbers preceding the powers of 10 and then add the exponents of the two powers of 10. For instance,…

The radioactive element carbon 14 has a 1/2 life of 5750 years a scientist determined that the bones from a mascot on had last year to 2.8% of their cardboard 14 how old were the booms at the time they were discovered wrong to the nearest integer as needed

An FM radio station broadcasts news at 98.0 MHz. What is the frequency of this FM radio wave in hertz?   What is the wavelength of this FM radio wave in meters? Round to the nearest tenth.   Given that λ = c/ν; the speed of light, c = 3 × 10^8 m/s Answers with scientific notation should be written in the format of a coefficient number with "e" and the power e.g., 3.8x104 should be written as 3.8e4

What is the wavelength, in nanometers, of light with an energy content of 2.89 x 102 kJ mol-1? Hint: The unit mol1 should be interpreted as "per mole of photons". Enter your answer with three significant figures. Enter scientific notation as 1.23E4. Énter only numbers in your answer. (Do dot include units.) Number nm Ouestic

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 incorrect

Please answer question 3

X-rays have a wavelength small enough to image individual atoms, but are challenging to detect because of their typical frequency. Suppose an X-ray camera uses X-rays with a wavelength of 5.67 nm . Calculate the frequency of the X-rays. Round your answer to 3  significant digits.
