1.Earth-sun distance=149,597,890 km(approx)
earth-moon distance= 356400 km to 406700 km(approx)

2.climbers are plants that feed and/or gets support from other plants.

3.center of gravity of the body needs to be shifted while climbing.cuz center of gravity pe gravitational force lagti hai.and jab center of gravity aagay ki taraf barhate hain to asani hoti hai climbing main.

shall i explain these further, or you got it?

1. why lunar eclipse lasts longer than solar?
In lunar eclipse, Earth comes between sun and moon while in Solar Eclipse, moon comes in between Sun and Earth. Ofcourse, since Earth is larger than moon, Lunar eclipse lasts longer than the Solar Eclipse.

3.concept of equilibrium in description of why a person bends while climbing on trees?
Climbing on trees? I believe you have mistaken this for climbing on mountains. While bending, the centre of mass is lowered and thus attaining equilibrium is rather less difficult. (HINT: Imagine balancing a long and a short stick. Which one do you think would be easy?)

ans 1: it is because the size of the size of moon smaller than the sun...
ans2: i am still confused
ans3: (i think the question is for mountain or slope raher than tree) it is because of the balance of body with the gravity..whn there is slope and u stand straight the gravity will pul u back,and if u bend while climbing it would balance with gravity..when u come down on the slope u keep ur body straight and slow it is also because of gravity,if u bend while coming down there are mre chances to fall...

hopefully this ans would help u a lil..
regards...

that's exactly what I've written,climbers are plants that feed and/or climb on other plats because their stems are weak and need support from other trees/plants.
