Whoever answers correctly gets brainliest what is the similarity between object a and object b? [ ] both have the same slope. [ ] both move with variable speed. [ ] both move with constant speed. [ ] both start the journey from the same point.

both move at a constant speed.

Explanation:

As you can tellThey are both straight lights both going t a certain point. They definently dont start the same journey on the same point so cross that one out. They dont move with variable speed so. And they dont have the same slope. If they had the same slope they would have the same direction all together. So they are going at a constant speed together because no matter where their point is, they are going to be going around the same rate.

iron would move it is magnetic there is a mag field around the current in the wire

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
