Answer:
Step-by-step explanation:
Distance has to do with how far an object or a body has travelled. If a hiker starts at point P and walks 2.0 kilometers due east and then 1.4 kilometers due north, the total distance covered by the hiker will be:
Distance = 2.0km + 1.4km
Total distance travelled = 3.4km
The displacement is the distance covered in a specified direction. This is expressed using the Pythagoras theorem as shown:
R² = 2.0²+1.4²
R² = 4+1.96
R² = 5.96
R = √5.96
R = 2.44km
Hence the magnitude of the hiker’s displacement vector R is 2.44km

Answer:
20.7 mL
Step-by-step explanation:
There is 56.6 mL of solution in the bottle. 3.2 mL is used up.
This leaves us with 53.4 mL (56.6 - 3.2). Then, half of this amount is used up.
This leaves us with 26.7 mL (53.4 ÷ 2).
Then, 6 mL of this is poured out. This leaves us with 20.7 mL (26.7 - 6).
