Draw an x y axis
3 miles west is 3 miles to the left, -3
4 miles south is 4 miles down, -4
connect the the point to the origin, that side is what you are looking for
that side is also hypotenus
using Pythagorean theorem
sqrt(-4^2 + 3^2)
sqrt(25)
5
your displacement is 5
True, charge can not be created or destroyed, only transferred
Answer:
The height of the airplane is 3312.4 meters.
Explanation:
Given that,
Speed of the airplane, v = 1100 km/h = 300 m/s
It takes 26 s for the engine to hit the ground. We need to find the height of the airplane. Using second equation of motion to find it as :

Here, u = 0 and a = g

The height of the airplane is 3312.4 meters.
It is real, however it gets inverted in the retina and flips back in the cornea
<u>Answer:</u>
1) Distance traveled by bird = 403 meter
2)Average speed = 1.66 km /hour
3) Zcceleration = 2 
<u>Explanation:</u>
1) Distance traveled = Speed * Time taken = 31 * 13 = 403 meter.
2) Average speed = Total distance covered / Time taken for that distance to cover.
Total distance covered = 2+0.5+2.5 = 5 km
Time taken = 3 hours
Average speed = 5/3 = 1.66 km /hour
3) Acceleration is defined as the rate of change of velocity, so acceleration a = change in velocity/time.
Change in velocity = 14 - 6 = 8 m/s
Time = 4 seconds
So acceleration = 8 / 4 = 2
