Walk 42 miles due north, deviate 78 degrees to east, and walk 65miles. what is the displacement? ( magnitude and direction with respect to north). a) show work through calculations for predictions

84.405m,

Explanation:

Given

Person walk 42 miles due to north  so its position vector is

Now he deviates to east and walk 65 miles

so its new position vector

So magnitude of acceleration is

for direction

volts times amps 6 x 0.5 3w

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
