Answer:
False. The net force is Zero
Explanation:
To answer this question we propose the solution of the problem.
We have a toy where balls come in and out after crashes between them, this toy forms our system, so all the balls are parts of the system, when the balls collide with each other according to Newton's third law force and action and reaction, so it has the same magnitude, but opposite direction, this is each is applied to some of the objects.
In conclusion of the previous one for the system the net force is Zero, all are internal. Therefore, the only thing that happens is a redistribution of speeds according to the conservation of the moment.
Let's review the answer.
False. The net force is Zero
The correct answer would be to express large and small numbers.
The second one is the answer
Answer:
<em>The magnetic field's direction is towards the north</em>
<em></em>
Explanation:
The force on a positive charge in a uniform magnetic field is represented by the right hand rule. To determine the direction of the force, place your right hand with your palm up, and your thumb at 90° to the other fingers. If the fingers represent the magnetic field, and the thumb the direction of the positive charge, then the palm will push up in the direction of the force. But a negative charge like an electron pushes in exactly the opposite direction. So if you follow this rule, you will find that the magnetic field points towards the north.
