Klio2033 [76]

In the Earth’s Northern Hemisphere, summer is about 94 days long, spring is about 92 days long, fall is about 90 days long and w
aleksandr82 [10.1K]

Answer:

T = 94 days which is summer season

Explanation:

As we know by Kepler's law of motion that Earth moves faster as it comes closer to the sun and it moves slower as it moves away from the sun

So here the longest season must be the slowest speed of the Earth about the sun

And similarly the shortest season is the fastest speed of earth with respect to the position of sun

Also we know that earth moves fastest when it is closest to the sun and when earth is farthest from the sun then earth moves slowest speed

So here we need to find the season when earth is farthest position from sun so it should be slowest speed and hence longest time period

so correct answer would be

T = 94 days which is summer season
