Answer:
The man's velocity relative to the moving walkway is, v₂₃ = 0.2 m/s
Explanation:
Given data,
The speed of the moving walkway, v₁₂ = 0.9 m/s
The speed of the man walking on a walkway to the stationary observer, v₁₃ = 1.1 m/s
The speed of the man walking on a walkway to the walkway, v₂₃ = ?
The formula for relative velocity is,
<em> v₁₃ = v₁₂ + v₂₃</em>
∴ v₂₃ = v₁₃ - v₁₂
Substituting the values,
v₂₃ = 1.1 - 0.9
= 0.2 m/s
Hence, the man's velocity relative to the moving walkway is, v₂₃ = 0.2 m/s
B. 0.5 km to the North. if its going 2 km/h, just take the time (.25 hours) and divide it by the speed, and you've got distance.

Answer:
120 mL = 120 cm^3
Explanation:
1 mL is <em>equal</em> to exactly 1 cubic centimeter, so 120 mL = 120 cm^3

If you ever come back again, with one that has
an AC source and an L or a C in the circuit, I'll
be looking for more than 5 points for that one. :-)
