Answer:
7.06454224 Newtons
Explanation:
C = Drag coefficient = 0.8
ρ = Density of air = 1.204 kg/m³
A = Surface area = 1 m²
v = Velocity of wind = 7 min/mi = 3.83 m/s
The Drag force is given by
The drag force exerted on the runner is 7.06454224 Newtons
Hey - for this problem you will find out your new velocity (similar to speed)
You take your Initial Velocity and add to it all the gained velocity you get during this process (which is the Acceleration multiplied by the amount of Time you are accelerating for)
So we get (Final Velocity) = (Initial Velocity) + (Time)(Acceleration)
In your equations, thats (Final Velocity) = (10 meters/second) + (5 seconds)(2.1 meters/second/second)
Which is 10 + 10.2 = 20.2 meters/second
Answer:
Crest is the highest point that a wave reaches and… Trough the lowest point that a wave reaches............Transverse waves are waves whose particles vibrate at right angles to the direction of wave travel e.g water wave. .....,.......longitudinal I think it's not "longitudin" are waves whose particles vibrate in a direction parallel to the direction of wave travel e.g sound wave
