I think A is the correct answer because its high is more higher compared to the others, and the mass really does not matter, to know the gravitational potential energy, we need to know how high the object is located because gravity does not show any favor to an object that has more mass or an object that doesnt
I can answer number 2 for you only. I don’t know if it’s correct or not this is what I THINK it is:
2. Burning fossil fuels creates greenhouse gases, which changes the climate.
Ps. Climate is long term weather. Aka weather over a long period of time.
14-6 =8
8/4= 2m/s per second
The troposhere is the lowest layer of the Earth's atmosphere and the thermosphere is the second, above the mesosphere and below the exosphere.
Thermosphere is the largest of all the layers. It is within the thermosphere that ultraradiation causes ionization.
The troposhere is where 99% of the water vapor and aerosols are found. It is denser than the layers above it because of the weight compressing it. The troposphere as well contains approximately 75% of the mass of the atmosphere. Most of the world's weather takes place in the troposhere.
