What will happen to the two objects in the picture as they are slowly moved toward each other?
A.
The objects will be pulled toward each other.
B.
The objects will both be pushed in the same direction.
C.
The objects will push away from each other.
D.
The objects will not affect each other.

Option A. The objects will be pulled toward each other.

Explanation:

If two objects are placed at a certain distance from each other and one object is placed at right side while other is placed at left side. If we want to reduce the distance and close both of them. We have to push them by applying force on each other. By pulling them towards each other will decrease the distance between them and finally they meet with one another.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

e) all of the above

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
