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

photocells convert light energy to electricity

measure their densities same density, same sub
