can the rectangular components of the vector be greater than the vector itself The Correct Answer and Explanation is: Correct Answer:No, the rectangular components of a vector cannot be greater than the vector itself in magnitude. Explanation: In physics and mathematics, a vector is a quantity that has both magnitude (length) and direction. Every vector […]

Explain why a vector cannot have a component greater than its own magnitude. A vector cannot have a component greater than its own magnitude because it violates the principles of vector addition and subtraction. The magnitude of a vector represents its length or size, while the components of a vector represent its direction and magnitude

Answer the following question in scientific notation rounded to 2 decimal places. Do not show your work here. Note: We only accept scientific notation including “E”. Use 1.23E5 to represent 1.23 x 10^5. 1) (5.42E03)(4.35E-01)(6.35E-09) = E-2 2) (7.53E02)(4.92E07)(3.98E-02) = E-3 3) (6.98E-05)(1.56E07)(2.92E08) = E-4 4) (3.39E00)(3.14E01)(3.66E07) = E-5 5) (4.21E-02)(5.48E-08)(3.13E-06) = F-1 6) [(3.98E-01)(7.60E11)]

How do you write 25.4 millimeters in scientific notation The Correct Answer and Explanation is: Correct Answer:25.4 millimeters in scientific notation is 2.54 × 10¹ millimeters. ExplanationScientific notation is a way of expressing very large or very small numbers in a more compact and manageable form. This format is especially useful in science and engineering,

Why rna primer is synthesized in dna replication instead of dna primer The Correct Answer and Explanation is: Correct Answer:RNA primers are synthesized instead of DNA primers during DNA replication because the enzyme that initiates the synthesis of a new strand, primase, can only synthesize RNA primers. DNA polymerases cannot begin synthesis on a bare
