PLEASE ANSWER MY 2 QUESTIONS IN SCIENCE THANKS
3.when a negatively charged object moves in the opposite direction of an electric force field,the potential energy of the object.
A.becomes zero(I PICK THIS)
B.increases
C.decreases
D.stays the same
4.the two south pole ends of two magnets are touching.Which of the following can be concluded?
A.no work was requried by an outside force.
B.the magnets are naturally attracted to each other.(I PICK THIS)
C.work was required by an outside force.
D.the potential energy of the magnets is low.
#2. Don't the two ends repel each other since both are are the same? That means work must be performed in order to push them together.
I don't understand 3.
yo DrBob222, what about #1?
oh, sorry I miss-read.
DOES ANYONE KNOW #3!?!?!
To answer your first question:
3. When a negatively charged object moves in the opposite direction of an electric force field, the potential energy of the object:
To find the correct answer, we need to understand the relationship between the direction of movement and the electric force field. Typically, negatively charged objects move towards regions with a stronger electric force field.
In this case, the object is moving in the opposite direction of the electric force field. Since electric potential energy arises from the interaction between charges and electric fields, when the object moves against the electric force field, it is moving towards a region of lower electric potential energy.
Therefore, the correct answer is:
C. The potential energy of the object decreases.
Now, let's move on to your second question:
4. The two south pole ends of two magnets are touching. Which of the following can be concluded?
Magnets consist of north and south poles, and opposites attract while similar poles repel. So, when two south pole ends are touching, this situation can be concluded as follows:
The correct answer is:
B. The magnets are naturally attracted to each other.
Since the south and south poles repel each other, in order for them to be touching, an outside force must have been required to overcome this repulsion. The fact that they are touching indicates a force pulling them together, hence the conclusion that the magnets are naturally attracted to each other.
I hope this helps clarify the answers to your science questions!
