It’s c Because is the one the makes the most sense
Bigger change in velocity because the object is lighter than the object with more mass so it would move further (sorry it’s not a great explanation)
The best conclusion that can be drawn is that D) A current does not flow in the wire
The distance between city a and city b is 833.345 miles.
We know that
1°=60'
The distance of city a from the initial ray is calculated as
x_a=3960*tan45.46°=4024.101 miles
The distance of city b from the initial ray is calculated as
x_b=3960*tan 38.86°=3190.75 miles
Now the distance between city a and b is equal to
4024.101-3190.75=833.345 miles
This is the vertical distance between the cities.
