Question

ученикам 7 класса (!) вопрос 2121На какого из альпинистов будет действовать большая сила тяжести:1)на того, кто начинает восхождение2)на того, кто уже достиг вершиныответ:+1 подробно:+2 с картинкой:+3 видеоролик:+4 чудесный:+5

Answer 1

ммм, на того кто только что начал восхождение. т.к.  он находится у самого осонования горы, и ближе всего к земле, тоесть  g=G*(mз+m альпиниста) \ R

у того алпиниста, который на определенной высоте уровнение будет выглядить так   g=G*(m3+mфльпиниста)\ R + h(высота на которую он взобрался)  

таким образом, действующая сила тяжести на первого альпиниста будет больше, чем та, которая действует на второго. 

Answer 2

The Effect of Gravity on Mountaineers

The force of gravity affects all objects on Earth, including mountaineers. In this case, we are considering the effect of gravity on two different mountaineers: one who is beginning their ascent and one who has already reached the summit.

1) The mountaineer who is beginning their ascent: When a mountaineer starts climbing a mountain, they are still close to the surface of the Earth. At this point, the force of gravity is acting on them with its full strength. Gravity pulls the mountaineer downward, making it harder for them to climb upward. The mountaineer must exert more effort to overcome the force of gravity and ascend the mountain.

2) The mountaineer who has reached the summit: Once a mountaineer reaches the summit of a mountain, they are at the highest point of their ascent. At this point, the force of gravity is still acting on them, but its effect is slightly reduced compared to when they were at the base of the mountain. This is because the mountaineer is now farther away from the center of the Earth, where the force of gravity is strongest. However, it is important to note that the difference in gravity's effect between the base and the summit of a mountain is relatively small and may not be noticeable to the mountaineer.

In summary, both mountaineers are subject to the force of gravity throughout their climb. However, the mountaineer who is beginning their ascent will experience a greater force of gravity compared to the one who has already reached the summit.

I hope this explanation helps! Let me know if you have any further questions.
