Answer:

Check explanation.

Explanation:

Net force is essentially the sum of the forces enacting upon an object. One example of net force is gravity and normal force. It is commonly accepted that every object has a force acting upon it, even if it is stationary. To give an example, the weight of an object has a force upon the earth but the earth pushes back, essentially meaning that the object will not sink.

Answer:

Magnets can create electricity and electricity can create a magnetic force.

Both electric charges and magnets do not have to touch an object in order to exert a force on it.

Electromagnets use electricity to create a magnetic force.

Answer:

It involves observation

It involves experimentation

It is supported by evidence

Explanation:

Science can be described as a system of knowledge based on the understanding of the natural world. The subject of science requires the scientific method - a chronological series of steps that have to be followed while trying to understand events in the natural world. These steps are:

observation
formulation of hypothesis
testing of the hypothesis by experimentation
conclusion based on available evidence from the experiment

Hence, science involves observation, experimentation, and it is supported by evidence.

sleet_krkn [62]

Answer:

Explanation:

The potential difference between one side of the wire causes the electric field inside the wire (causes the electrons to flow). However, inside the wire, it is still neutral. The electrons are just moving, the wire is not gaining or losing electrons.

If a box is pulled straight across the floor at a constant speed and it is pulled with a horizontal force of 48 N., what is the

Dima020 [189]

If its speed is constant and it's moving in a straight line, THAT's "constant, uniform motion". That can only happen when there's NO net force on the object.

So besides the 48 N forward that the puller is giving it, there must be friction with the floor, or mosquitoes all over it trying to fly backwards, or somebody crouched down behind it pulling it backwards, or some other kinds of things going on, that all add up to 48 N BACKWARDS.

Somehow, the NET force on the box has to be zero, because of the way it's moving.
