Calculate the displacement of a bee that flew out of the beehive due east for 4 km, went around a 0.52 m in diameter poplar tree

, traveled 6 km west, stopped to get a drink at a local watering puddle, and flew 2 km west to the field of flowers.
Please help, thank you!
I'll give you 100 points.

My answer is around 9.21 meters because I drew a diagram and it formed a triangle. I used the pythagorean theorem to find the shortest route and then added the 2 km west to the field of slower.

Which of the following determines the range of spectral lines produced during electron transition?. . A.The total number of ener
KengaRu [80]

Answer: A.The total number of energy levels the electron can jump to.

Explanation:

Spectral lines are bright or dark lines over continuous spectrum which occur due to emission or absorption of energy.

When an electron jumps to or from one energy level to another energy level, spectral lines are produced. The range of spectral lines depends on the number of energy levels available to which the electron can jump. This depends the amount of energy gained/lost by the electron.

Thus, the correct answer is: A.The total number of energy levels the electron can jump to.
