4 newtons, 4 amps, 4 joules, 4 watts, 4 ohms, 4 volts
what does I=
Answers
Answer:
I amperes
Explanation:
Newton is the unit of force. Hence 4 newton is not the current “I”
Joules is the unit of energy and hence it do not signify current I
Watt is the unit of power i.e the rate of transfer of energy.
Ohm is the unit of resistance produces thereby obstructing the flow of current
And Volts is the unit of voltage or potential difference between two ends of an electric circuit. Thus, it is also does not signifies current.
Thus, I amperes

Answer:
Image B represents the force on a positively charged particle caused by an approaching magnet.
Explanation:
The most fundamental law of magnetism is that like shafts repulse each other and dissimilar to posts pull in one another; this can without much of a stretch be seen by endeavoring to put like posts of two magnets together. Further attractive impacts additionally exist. On the off chance that a bar magnet is cut into two pieces, the pieces become singular magnets with inverse shafts. Also, pounding, warming or winding of the magnets can demagnetize them, on the grounds that such dealing with separates the direct game plan of the particles. A last law of magnetism alludes to maintenance; a long bar magnet will hold its magnetism longer than a short bar magnet. The domain theory of magnetism expresses that every single enormous magnet involve littler attractive districts, or domains. The attractive character of domains originates from the nearness of significantly littler units, called dipoles. Iotas are masterminded in such a manner in many materials that the attractive direction of one electron counteracts the direction of another; in any case, ferromagnetic substances, for example, iron are unique. The nuclear cosmetics of these substances is with the end goal that littler gatherings of particles unite as one into zones called domains; in these, all the electrons have the equivalent attractive direction.
Final answer:
A positively charged particle will be deflected by the magnetic force when it approaches a magnet. Look for an image in which the particle's path deviates away from the magnet. Without the images, a specific selection cannot be made.
Explanation:
The question relates to the force exerted by a magnet on a positively charged particle. A magnet has two poles, North and South. A positively charged particle moving towards a magnet will be deflected by the field, with the direction of deflection dependent on the specific pole it is approaching. Without the images being provided, it's hard to give a definite answer. However, you should look for an image where the particle's path deviates away from the magnet, as this represents the magnetic force applied to it.

We already know that from everyday life examples such as simply pushing a car that if 2 people push a car on a flat road it will accelerate faster than if one person was pushing it... Therefore, there is a relationship between the size of the force and the acceleration.
Now onto the third law of motion. First of all, what is the third law of motion? Well, a force is a push or a pull that acts upon an object as a results of its interaction with another object. Forces result from interactions! According to Newtons third law, whenever one object, and another object interact with each other, they exert forces upon each other. "For every action, there is an equal and opposite reaction." The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. So, how is this important to everyday life you may ask?
Well, the action-reaction force pairs are found everywhere in your body.
For example, right now as I am typing, my tendons are exerting forces on bones, and those bones exert reaction forces on the tendons, as muscles contract, pulling my fingers on the keys. I press on those keys, and they press back on my fingers. See? Since im pressing on the keys, the press back on me. Its opposite from eachother, as stated in the quite above. "For every action, there is an equal and opposite reaction."
