When a comet passes near the sun, it experiences a force that causes it to change direction. what causes this force?

I believe this force is GRAVITY .

Also known as the slingshot effect, the comet experiences a gravitational pull towards the sun, but the comet is too far away for it to go into full effect, so when the comet flies by, instead, all it does is change direction.

Hope this helps!

Gravitational Force

Explanation:

The answer is Gravitational Force produced by these two bodies. We know gravitational force is the weakest force among all the forces present.

So , these force are not significant for large distance but as the comet passes near the sun the force came into consideration and it experience change in direction.

Again note that since, the force is too weak. Therefore, comet do not collide with the sun rather its direction changes to some extend.

Its not gravity because gravity is a special term used if and only if when one of the body among them is Earth.

overcharge is the right answer system

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
