The second option is correct, because planet A has the shortest orbit and planet C has the longest one.

A,B,C are three planets with the same mass,then it means they have also the same gravity,so what matters here is the distance between the Sun,more exactly,their orbits.
⇒ The shorter the distance from the Sun, the more a planet completes an orbit. ⇒ Correct affirmation : Planet A will take the shortest time to complete an orbit, while planet C will take the longest time.

The first affirmation is false because the planet A is the closest to Sun,so logically,it will complete the orbit faster than the others.

The affirmations 3 and 4 are incorrect because their gravity is equal and because the distance between the planets and the Sun differs from one planet to another.

Which kind of wave would be observed in outer space between planets, where there is very little matter?

Ahat [919]

Electromagntic wave, such as an X-ray.

Explanation:

Electromagnetic wave does not require any medium to travel. These waves propagate outwards from the source.
They can travel even through the vacuum of outer space.
The major source is the sun which emits radiation in the form of the Electromagnetic spectrum.
These waves travel through oscillating electrical and magnetic fields generated by the oscillating charged particles.
These waves oscillate in the perpendicular direction of planes concerning each other and are in form.
Electromagnetic waves travel at speed of light.

Answer:

Explanation: people interact with the environment in a positive way by throwing away their trash, and being respectful to the environment, people impact the environment in a negative way by, leaving their trash to fly away into the ocean or something, and by driving their cars a lot, even people who work in factories they produce pollution too. The environment affects humans in a positive way by being nice and pretty and all the flowers, it make us humans happy, and like oceans and playgrouds they give people exercise by just moving around. The environment affects people in a negative way by natural disasters causing floods and people's houses get ruined or someone getting like poison ivy, that's not good.

Which of the following is considered the most important and yet most threatened ecosystem on the planet? coastal wetlands rainfo

Artyom0805 [142]

The answer is rainforests. The destruction of rainforests can lead to global warming due to the accumulation of carbon dioxide as a greenhouse gas in the atmosphere. This is because rainforests are major carbon sinks because they sequester carbon dioxide from the atmosphere. One of the major rainforests that are facing the threat of human activities is the Amazon and Congo forests.

The answer is south america’s location atop the Nazca and South American plates of the circum-pacific belt. The circum-pacific belt is also known as the ‘ring of fire’ because there is a subduction zone in the region. The Cocos plate is subducting under the Caribbean Plate. This creates friction between the two plates with occasional release of high amounts of energies when a stuck region gets unstuck abruptly. This region accounts for approximately 90% of the world’s earthquakes.
