Analyze the graph below. What is the average speed of the bus?

2500 m/min

100 m/min

2000 m/min

500 m/min

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
