. Calculate the distance between the planes after 6 hours. Give your answer in km, to the nearest km. km
Answer: 2392 kilometers.
Explanation:
To find the distance between the two aircraft after 6 hours, we can use the Pythagorean theorem because they are moving at right angles to each other (one due south and the other due east). Here's how to calculate it:
First, calculate the distance traveled by each aircraft in 6 hours.
1. Aircraft traveling south:
Distance = Velocity × Time
Distance = 85 m/s × (6 hours × 3600 seconds/hour)
Distance = 85 m/s × 21600 s
Distance = 1836000 meters
2. Aircraft traveling east:
Distance = Velocity × Time
Distance = 71 m/s × (6 hours × 3600 seconds/hour)
Distance = 71 m/s × 21600 s
Distance = 1533600 meters
Now, we have the two sides of a right triangle:
- The southbound distance is 1836000 meters.
- The eastbound distance is 1533600 meters.
We can use the Pythagorean theorem to find the hypotenuse (distance between the aircraft):
Distance = √(southbound distance² + eastbound distance²)
Distance = √((1836000 m)² + (1533600 m)²)
Distance ≈ √(3376416000000 m² + 2352089600000 m²)
Distance ≈ √(5728505600000 m²)
Distance ≈ 2391760.78 meters
Now, let's convert the distance to kilometers:
Distance ≈ 2391.76 kilometers
Rounding to the nearest kilometer, the distance between the two aircraft after 6 hours is approximately 2392 kilometers.
Answer:
A simple depolarization can be defined as any change that occurs in a neuron that results to it being more positive than resting potential, but an action potential happens only when the simple depolarization reaches the threshold or optimum level.

A nuclear energy is produced in a thermal power plant. A nuclear energy is produced in a nuclear reactor. In nuclear reactor nuclear fission reactions takes place in which an atoms absorbs energy from radiations and undergo fission and produces energy in the form of high intensity radiations along with heat. Although the fission reactions takes place in a nuclear reactor in a controlled way so that the radiation may not leak out from the reactor. The accidentally leak out radiations or explosion or bursting of the reactor due to uncontrolled thermal energy production can result in air pollution as the leak out air will cause bursting effects which will contaminate the air.
The nuclear waste are radioactive and are non-biodegradable these wastes are disposed off deep in geospheres and in water. They have potential to contaminate both land and water. Radioactive wastes can cause mutations in the genome of the organisms exposed to these wastes which generate deadly diseases and disorders. Therefore, these wastes are hazardous.
Answer: Hazardous wastes and potential reactor accident.
