N scientific notation. Assignment 1.3 AVERAGE MASS OF HOUSE FLY Adult housefly (Musca domestica) is having a mass of only about 0.000,021,4 kg. Express this number in standard form \/ scientific notation.<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

To express the mass of an adult housefly (0.0000214 kg) in scientific notation, follow these steps:<\/p>\n\n\n\n

1. Identify the Significant Figures<\/strong><\/h3>\n\n\n\n

The number provided is 0.0000214 kg. The significant digits are 214<\/strong>. We ignore the leading zeros because they don’t affect the value of the number.<\/p>\n\n\n\n

2. Move the Decimal Point<\/strong><\/h3>\n\n\n\n

To convert the number into scientific notation, you need to move the decimal point such that there is only one non-zero digit to the left of the decimal point.<\/p>\n\n\n\n

For 0.0000214<\/strong>, move the decimal point 5 places<\/strong> to the right: 0.0000214\u2005\u200a\u27f9\u2005\u200a2.140.0000214 \\implies 2.140.0000214\u27f92.14<\/p>\n\n\n\n

3. Count the Number of Decimal Places Moved<\/strong><\/h3>\n\n\n\n

Since the decimal point was moved 5 places to the right<\/strong>, this corresponds to a negative exponent<\/strong> in scientific notation (because the original number is less than 1).<\/p>\n\n\n\n

4. Write in Scientific Notation<\/strong><\/h3>\n\n\n\n

Now, write the number in the form of: Number\u00d710exponent\\text{Number} \\times 10^{\\text{exponent}}Number\u00d710exponent<\/p>\n\n\n\n

This gives: 2.14\u00d710\u22125 kg2.14 \\times 10^{-5} \\text{ kg}2.14\u00d710\u22125 kg<\/p>\n\n\n\n

Final Answer:<\/h3>\n\n\n\n

The mass of the housefly in scientific notation is 2.14\u00d710\u221252.14 \\times 10^{-5}2.14\u00d710\u22125 kg<\/strong>.<\/p>\n\n\n\n

\n\n\n\n

Explanation of the Process:<\/h3>\n\n\n\n

Scientific notation is used to express very large or very small numbers in a more manageable form. It involves two main parts:<\/p>\n\n\n\n

    \n
  1. A decimal number between 1 and 10.<\/li>\n\n\n\n
  2. A power of 10 that indicates how many places the decimal point was moved.<\/li>\n<\/ol>\n\n\n\n

    For example, moving the decimal point to the right for small numbers results in a negative exponent. In this case, moving 5 places gives a power of 10\u2212510^{-5}10\u22125, which reflects the smallness of the value.<\/p>\n\n\n\n
