Answer:
a

b
Explanation:
From the question we are told that
The velocity of the river due east is 
The velocity of the boat due north is 
The width of the river is 
Generally the velocity of the boat relative to the shore

=> 
=> 
Generally direction of the boat relative to the shore is mathematically represented as

=> ![\theta = tan^{-1}[ \frac{v}{v_1}]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20tan%5E%7B-1%7D%5B%20%5Cfrac%7Bv%7D%7Bv_1%7D%5D)
=> ![\theta = tan^{-1}[ \frac{1.5}{10}]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20tan%5E%7B-1%7D%5B%20%5Cfrac%7B1.5%7D%7B10%7D%5D)
=> 
Generally the distance covered by the boat in the direction of flow of the river before reaching the north shore is mathematically represented as

=> 
=>
Answer:
The terrestrial planets are closer to the sun.
Explanation:
A! The bright light will have taller more spread out waves while the dimmer light will have smaller closer together waves. Hope this helps!
