Numbers are expressed in standard form called scientific notation, which employs powers of:
Correct answer: C. 10
- A. 2
- B. 8
- C. 10
- D. 16
Explanation
A number is expressed in scientific notation when it is written as the product of a factor and a power of 10. Examples: Scientific Notation of 2,700,000,000 is 2.7 × 10⁹.

About Vectors and Equilibrium
Vectors have magnitude and direction, unlike scalars, and are combined by head-to-tail or parallelogram methods. Work covers rectangular components, equilibrium when the resultant force is zero, the scalar product for work and projections, and the vector product for torque and cross-product direction using the right-hand rule.
