1) Can change the velocity the system
2) Can change the acceleration of the system
3) Cannot change the velocity the system,
4) Can change the direction of motion
1.full honluhan it muddenly starts is an example for​

Answer 1

Explanation:

can't change the velocity of the system because this force exert equally in all directions

Answer 2

Answer:

OPTION (3) Cannot change the velocity of the system.

Explanation:

The internal forces acting on an isolated system cannot change the velocity of the system.

• The internal forces are those kinds of forces that are exchanged by the objects in the particular system.
• These forces might end up causing acceleration in different parts of the system but these forces will not cause any sort of acceleration in the center of mass of the whole system.
• For instance, people standing in a moving bus have no effect on the velocity of the bus. Here, the bus is the system while the people standing in it are the objects in that system.

Final Answer:

The internal forces acting on an isolated system cannot change the velocity of the system.
