If thermal energy is added to a liquid, what is the most likely thing that will happen to the substance?
Explanation:
When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation).

Box is kicked (given an initial speed), causing it to slide along a level floor. There is friction acting between the box and floor surfaces. What is true about this motion
Answer:
I would assume that the box slows down due to the frictional force between the floor and the box. In addition, the frictional force points opposite of the boxes motion. As we know, the box was given an initial speed, therefore, having an applied force. Hence, we can conclude that the frictional force opposing the motion of the crate is equal to the applied force but acting in the opposite direction. This frictional force is called static friction. When we increase the applied force (push harder), the frictional force will also increase until it reaches a maximum value.
Hope that helps!

Determine the electric potential energy for the array of three charges in the drawing, relative to its value when the charges are infinitely far away and infinitely far apart.
Although we do not have the diagram needed to answer this question, we can provide general information in that electrical potential energy is calculated based on the charges and the distance between them.
How do we calculate electric potential energy?This energy can be calculated using the value of the charges along with the distance between them with the formula Energy = [tex]k\frac{q1q2}{r}[/tex] in which q represents the charges whilst r represents the distance of separation. As we can see these values are inversely proportional to one another.
Therefore, we can confirm that we can calculate electric potential energy using the charges and the distance between them, which will be inversely proportional to one another.

In a diving team, you are the team leader and you have three orientation in a trip 1-the red sea (low density) , 2-Dead sea (high density), 3-Deep lake (Pure water),which place is the best to dive in with your team.explain your opinion.
Answer:
I choose red sea, because while diving, it will be more easier if the upward force is less(upthrust). since the upthrust increase with increase with density, it will be much difficult to dive in Dead sea than red sea.
1. since red sea has less density, it would have the minimum upthrust, which results in less resistance while diving.
it is also because, the pressure inside the liquid at same depth will be less in red sea, due to its density.

if you are riding on a train that speed past another train moving in a same direction on an adjacent track ti appears that the other train is moving backward why?
Answer:
If you are traveling with a relativity constant velocity, then you will interpret your reference frame as being at rest. Since you are moving faster than the other train, the other train is moving backwards relative to you. Seeing the other train go past your window from front to rear makes it look like the train is going backwards

An object experiences a certain net force that causes a certain acceleration. If the net force on the object is
tripled, what happens to the acceleration of the object?
Answer:
it increases
Explanation:
equal to opposite force so it would return the amount applied on it
If an object experiences a certain net force that causes a certain acceleration. If the net force on the object is tripled , then the acceleration of the object would become tripled as well assuming the mass of the object is constant.
What is Newton's second law ?Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.
As given in the problem if an object experiences a certain net force that causes a certain acceleration. If the net force on the object is
tripled,
If a specific net force acting on an item results in a specific acceleration. Assuming the mass of the item remains constant if the net force acting on it is tripled, the acceleration of the object would also be tripled.
Thus, the acceleration of the object would get tripled.
