2. The average human body cell is about 5.1 x 10-4 cm in diameter.
The diameter of a plant cell is 8.00x 10 -3 cm. What is the
combined diameter of the body cell and plant cell?
3. Sabrina walked 75 meters to the east. Then she turned 30 degrees to the left and
walked 25 meters. Determine the magnitude of Sabrina's displacement vector. A.
using component method B. using law of Cosine and Law of Sine
