Hello there.
Which of these statements best describes the role of creativity in science?
It helps scientists create theories which are universal.
"Ocean surface currents are beautifully depicted in the drawing that accompanies this question."
The velocity of the air relative to the runner is 5 m/s.
<h3>What is the relative velocity?</h3>
We must recall that velocity is a vector quantity and the relative velocity must be obtained vectorially. Thus we know that;
Velocity of the runner = 4m/s. due west
Velocity of the wind = 3m/s due south
The relative velocity is;
Vr = √(4)^2 + (3)^2
Vr = 5 m/s

Answer:
1.9
Explanation:
Efficiency=mechanical advantage/velocity ratio×100
95=M.A/2×100
95=50M.A
M.A=95/50=1.9
