Question

You are viewing the nowcast and predicted Gulf Stream surface ocean currents for the coming week. The map displays arrows that indicate the direction of flow with their lengths proportional to their speed. The color coding depicts water speed in m/s (meters per second). Comparison shows that the ________ arrows representing lowest current speeds are in regions of purplish-red fuchsia color.

Answer 1

To find the velocity of the Gulf Stream, convert the given velocities to their northward and westward components using trigonometry. Subtract the northward component of the ship's velocity from the total velocity to find the velocity of the Gulf Stream. Finally, calculate the magnitude and direction of the Gulf Stream's velocity using vector addition.

Step-by-step explanation:

The velocity of the Gulf Stream can be calculated using vector addition. We can break down the velocity of the ship into its northward and westward components using trigonometry. The northward component can then be subtracted from the total velocity to obtain the velocity of the Gulf Stream.

Step 1: Convert the given velocities to their northward and westward components using trigonometry.

Step 2: Subtract the northward component of the ship's velocity from the total ship's velocity to find the velocity of the Gulf Stream.

Step 3: Calculate the magnitude and direction of the Gulf Stream's velocity using vector addition.

Answer 2

.....short and low speed arrows representing lowest current speeds are in regions of purplish-red fuchsia color. E.g. a hurricane eye is typical low velocity winds, so surface waves would be the same.
